- Passenger vehicle bumper assembly plays very important role in case of an accident. Automotive industry is a very huge ground and research is still evolving. From this safety of passenger has to be focused on safety and comfortably. In this paper, the most important parameters of an automotive front bumper beam such as material, shape and impact condition are to be studied to improve the stiffness and strength. The strength of the bumper is investigated with energy absorption and impact force in maximum deflection situation. Similar bumper beams made of different materials are simulated to determine the deflection, impact force, stress distribution and energy-absorption behavior; these characteristics are compared with each other to find best choice of material. These designs had been studied by impact modeling using Finite Element Analysis software, LS DYNA to determine the energy absorption by analyzing the kinetic energy, displacement and impact force.

Approximately 2.5 million traumatic eye injuries occur each year in the United States. Eye injuries can be caused by blunt, penetrating and blast trauma to the eyeball, orbit or through the face. Eye trauma in sports is most frequently resulted from ball sport and contact sport. In car crashes, there were increased incident of eye injuries sustained by occupant due to an airbag deployment. The most ocular injuries sustained by causalities in the recent combat were related to explosive blast [1,2]. None of the published models incorporate eye within the orbit of an anatomically accurate head mode

Passenger vehicle occupants involved in side impact crashes historically tend to fatal damages compared to the frontal or rear impact crashes due to the very limited survival space. Doors are the prominent part of the vehicle in protecting the passengers in side impact crashes. There are side beams inserted into the door which can absorb energy and reduce the intrusion of the impacting object. The strength, location and appropriate design of these beams are very important to save passenger’s life in case of pole impact. Superior beam design can eliminate the dependency on other expensive passive safety equipment’s like seat belts and side airbags. In past 15 years a lot of research work has been done to reduce the crash related injuries. The side door beams support the door structure in such a way that door cannot collapse easily. It absorbs most of the impact energies coming from the other vehicle or due to pole intrusion.

- The chassis frame is a main structural component to which all the other parts are attached. The chassis frame acts as the skeleton of the automobile so it should be able to withstand against various load condition but at the same time, it should be light weighted to reduce the inertia effect. One of the major challenges in the automobile industry is related to regular maintenance of the vehicle which operates in villages that have uneven surfaces (bumps) which ultimately result in an extravagant asset for those customers. Now a day the focus of the manufacturing industries is to increase payload capacity on possible less weight of chassis . The main focus of the RND teams on the durability of the truck so in this Research, we also work on truck durability analysis. This paper presents the study of the solution which is already generated in the industries related to the design and analysis of a ladder chassis frame of heavy-duty vehicles. Stresses under static loading condition are the design factor considered in this paper
