COLLAPSABLE STEERING ABSTRACT: The steering wheel is the important cause of fatal injury for drivers in frontal collision. When frontal collision occurs, due to the kinetic energy of driver or occupant body, it moves forward against steering wheel and wind shield. Actually in a frontal collision forces will be first transmitted through driver’s feet which act as fulcrum so the body will rotate about it. For the taller driver steering works as fulcrum. Driver head & chest hit the steering or windshield which may cause severe injury or death. Considering the injury potential of steering wheel we are presenting a new idea Collapsible Steering Column (Mesh). What is the collapsible steering column? The collapsible steering column is a mechanism …show more content…

The steering column is the shaft directly under the steering wheel in which the ignition and automatic shift levers are often located. When the steering column was first invented, it consisted of a single, long, steel rod connecting the steering wheel to the steering gear box. While this single-piece construction was efficient, and effective in controlling the vehicle, it soon became apparent that its design was unsafe in frontal collisions. Under the single-piece system, when such an impact occurred, the steering column would often impale the driver as it was rammed toward the rear of the vehicle. The unsafe attributes of single-piece steering columns called for the invention of a safer steering column design, which is why BelaBarenyi designed the collapsible steering column to replace it. The safely enhanced construction of the collapsible steering column, no matter which design is used, absorbs, rather than transfers, frontal impact energy by collapsing or breaking upon impact. In this way, drivers involved in frontal impact collisions are able to avoid the dangers of non-collapsible steering parts. Though the designs for steering columns have varied since their inception, a typical collapsible steering column looks like two interlocking shafts that attach directly to the steering wheel and the

    I never knew the answer to this question, until I discovered that human cadavers are used for impact studies. In chapter four Roach visits Wayne State University to watch a crash stimulation. During the stimulation they wanted to see how much impact a human shoulder could withstand before serious injury. I never knew that cadavers played a role with car safety. I don’t agree that safer windshields and steering wheels is the result. I do believe it helps and benefits you, but I don’t think that it is the only result. ()

  • Exploring the Four-Wheel Steering System

    1515 Words  | 4 Pages

    The four wheel steering system is a relatively new technique to control the vehicle. In this system we can control the four wheels of the vehicle to make tighter turns and cornering in the space available in the industries. It makes the controlling of the vehicle easy and less time consuming. We can compare it with the AGVs used in industries to transport the goods and material to the workplace. The system is different from the AGV in terms of steering control and path decision. The steering control of the AGV is either front wheels or rear wheels. AGV works on the decided path and sometimes it takes time to move to the specific location. With the help of four wheel steering

  • The Strengths and Weaknesses Within My Medicine Wheel

    2025 Words  | 5 Pages

    In Aboriginal teachings, the medicine wheel is sacred because it represents the various components of a healthy, well-rounded individual. Like wellness, the medicine wheel represents an “active state of health in which an individual progresses toward a higher level of functioning, thus achieving an optimum balance” (as cited in Fain & Lewis, 2002, p. 7). The medicine wheel is divided into four major sections, each representing a major part of a person (physical, emotional, mental, and spiritual). In order to achieve balance in one’s life, one must analyze each of these components, and work to improve communications within one’s self. Intrapersonal communication is vital to the development of self-concept and self-esteem, which in turn, contribute to better communication and interpersonal relationships (Beebe, Beebe, Redmond, & Geerinck, 2008). Therefore, it is crucial that a person has a “genuine sense of worth [in themselves],” before they look to develop an understanding of another person’s life (social decentering) (Beebe et al., 2008, p.47). This paper will serve as a means to assess my own intrapersonal communication in each of these four categories, using the medicine wheel described in Mussell (2005). In doing so, I hope to gain insight of how to improve my intrapersonal communication in each aspect of my life, which will, in theory, contribute to an increased ability to communicate with others (interpersonal communication).

    During side impact crashes, cars can potentially flip. Side impact crashes are said to be the most dangerous type of car crash. The rear facing seat is the best option during this type of crash. If the car flips the sides of the seats are better equipped to harness the child in the seat. The seat is able to make pivoting motions because of the attachments to keep the child in a straight line. Keeping them in a straight line reduces the risk of injuries especially in the spinal cord.By having their back straight it won't bend or come close to snapping. A rear facing car seat protects the child by using a 5- point safety harness which is a system of hooks even used for race car drivers, and flight pilots.This allows the child to stay In the seat without them fal...

    First of all, before I go into the presentation. I would like to ask you all that, have you ever experience in the car crash situation? We all know that when the car crash, the airbag will come out to protect the driver and the passenger on the front seat. However, imagine that what will happen if the airbag didn’t come out? The driver and the front seat passenger can be hurt or even dead if the car crash intensely. So, it is very important to check if the airbag of your car work properly or not and if not, that will be a big problem.

  • Structural Crashworthiness Theory

    1828 Words  | 4 Pages

    Crashworthiness of a material is expressed in terms of its specific energy absorption, Es=F/D, where F is the mean crush stress and D is the density of the composite material. In order to protect passengers during an impact, a structure based on strength and stiffness is far for being optimal. Rather, the structure should collapse in a well defined deformation zone and keep the forces well below dangerous accelerations. However, since the amount of absorbed energy equals the area under the load deflection curve, the two above mentioned criteria are somewhat contradictory, thus showing that, it is not only important to know how much energy is absorbed but also how it is absorbed, i.e., how inertial loads are transferred from impact point to panel supports. Therefore, in addition to designing structures able to withstand static and fatigue loads, structures have to be designed to allow maximum energy absorption during impact.

    Crashworthiness is the term used to measure a vehicle’s performance under impact conditions. A good design will be neither too strong (in which case the occupant would undergo very high acceleration) nor too weak (in which case the vehicle would absorb too little energy and not protect the occupant compartment from deformation). On the other hand, in term of mass, low mass is desirable for performance (acceleration and handling), fuel economy, and material

  • Crumple Zone: The Force And Impact Of Collisions

    302 Words  | 1 Pages

    The force and impact of collisions have truly been based off the material that cars have been built with. In the past, cars were built with heavy parts and steel as it was believed to be a safe way to protect occupants in the car as the structure would be more solid. Although, this is not the case since with a heavier and stronger body, the time of the collision would be very minimal which would overall increase the force of the impact based on the car’s specific velocity and mass. On the other hand, modern cars utilise a specific feature called a Crumple Zone. The Crumple Zone is implemented in cars through the way they have been shaped with the metal. The metal in the outside of cars have been heated, cooled, and molded in a way to be able

    Suspension system is used to absorb shocks and jerks from road or rough terrain. Suspension allows wheel to move independently to the body. Suspension components, wheel rims and brake components are known as un-sprung masses, which is important for better ride quality as well as it is meant to reduce the total vehicle weight. Comfort can be achieved by isolating the riders from road disturbances like bumps or potholes and Control is achieved by keeping car body from rolling and pitching, and maintaining good contact between road to tyre.

  • Physics Of Collisions Essay

    When it comes to cars, there are plenty of safety features incorporated by manufactures to ensure a smooth and safe ride. Some of these features seat belts, airbags, and antilock brakes. Nowadays, there have been great improvements to technology within cars to aid in the avoidance of collisions altogether. Examples of these technologies include blind spot detection, backup cameras, 360-degree cameras, and autonomous driving. Many of these newer safety features are there to avoid collisions. However, whenever a collision does occur, there is not much there to protect passengers in the rear of the car. Looking into this, there is evidence that shows that rear passengers do obtain injuries in collisions and pose the threat of contributing to others injuries. So, why are rear passenger airbags not standard in your vehicle?
