Impact Performance Analysis and Optimization of X-Sandwich Panels

Abstract:

In this paper, ANSYS/LS-DYNA which is a non-linear dynamic finite element software is applied to simulate the processes of two kinds of X-sandwich plate hit by a rigid sphere. Ultimate-ly the sandwich plate can be used to replace some components of the traditional steel protective dev-ices aimed at improving the overall crashworthiness performance of protective devices. This paper analyzes the influence of two plates on crashworthiness. And based on the comparison between the sandwich plates and the equivalent flat plate, the results from numerical simulation show that the X-sandwich panel can provide an excellent crashworthiness.Tight type of X-sandwich board is perfor-ms better than the discrete and ordinary steel plates, which can be applied to bridge protection device.
