A Review on modern vehicle Virtual Crash Test to Understand the Effect of Impact on Passengers

Abstract

Modern vehicles are much safer, lighter, faster and drive convenient as far as older vehicles are concerned. They are more stable and having better safety features. Now a days everyone is giving more importance to the passenger safety. In order to avoid the passenger threats during vehicle crash, we need to understand the collusion effects on vehicle body and passenger cabin. It can be studied well with the help of crash test where vehicle is allowed to hit an obstacle with a particular speed and due to hitting vehicle damage and effect of collusion on the cabin is observed. But physical crash test is much costlier and consumes money, effort, material and much more things. To avoid this virtual crash test is preferred in industry. It is a simple computerised crash test simulating process in which virtual model of vehicle is allowed to hit a virtual obstacle with a known speed virtually on computer. The effects will be generated by finite element analysis module in the form of deformation and stresses on virtual parts. It also shows the bending and cracks on parts. Hence this virtual crash test is Having 95 % accurate results. It also avoids physical damage on vehicle, saves efforts and money. In this paper we have studied the various literatures available based on this crash test. Authors opinions are understood and based on their opinions a standard conclusion is drawn. This study will help to conduct virtual crash test with the help of FEA package and CAD Tool.
