Crashworthiness Analysis of a Thin-Walled Structure in the Frontal Part of Automotive Chassis
Main Article Content
Abstract
With increasing road accidents, researchers found a need to reduce the impact which gets transferred to the driver and passengers during a collision. Chassis is the main rigid component which transmits the impact or jerk to the entire vehicle. So, the changes can be done in the frontal head tube shape in order to achieve maximum energy absorption. The objective of this article is to produce a thin-walled impact absorption structure. The unique strength absorption, the maximum crushing force, all through the frontal impact are the primary dimensional parameters of the performance. Explicit dynamics feature of Ansys can be used and the results of Peak Force (PF) and Specific Energy Absorption (SEA) can be acquired virtually. Based on the results, the shape with the highest amount of SEA can be concluded as the best shape so that it can be used to absorb the maximum energy while collision of the vehicle takes place. The results show an increment of 30% in SEA.
