Virtual Crash Test Analysis of Modern Car through ANSYS Software

Abstract

Today's world is more curious about the automobile safety performance. Everyone, who wishes to purchase their own vehicle, is concentrating on the safety features of the vehicle so that his journey must be safe. Most of the automobile companies in India now a day are focusing on the strength improvement of vehicle. In order to achieve the maximum safety the vehicle must undergoes the different types of test, which is to be performed during the design and development phase. Individual companies follow their own testing methods, but out of them some tests are common and must be taken before launching the vehicle in the market. Crash Test is the one of the important test which is to be conducted during the development of car. It is the method of hitting the car on an obstacle with a particular speed in order to observe and record the damage on vehicle, passenger and percentage of failure of component. This test is to be carried out with strong observations and standard speed. There are two methods of conducting crash test. One is physical crash test and other is virtual crash test. Physical crash test is time consuming, having wastage of money, material and efforts. But the plus point is it has accurate results. While virtual crash test eliminates all the above lacunas of physical crash test but the results are approximate. In this paper the modern vehicle like car crash test is to perform by using Virtual CAD Model and CAE tool like ANSYS 2020 R1 workbench. The vehicle is to be allowed to hit an obstacle with a particular speed and percentage of damage along with maximum deformation and stress concentrations is to be studied well. Three different materials are to be tested in order to achieve the better results. Based on obtained results, results are drawn.
