Abstract :
To make the crank slider protective devices to meet the requirements of regulation, optimization was carried out to the absorbing thread of the crank-slider-CST protective device. Based on the finite element model in VPG and simulation in LS-DYNA, with the orthogonal optimization design, obtained the parameters of the absorbing thread. The crash speed in these simulations is 50km/h, which is higher than the regulatory speed. The simulation showed that all indexes could meet the regulation very well, and the effectiveness of the device was demonstrated.
