| 摘 要： | 以满足后下部防护装置的法规要求为目标,对设计出的一种曲柄滑块式CST货车后下部防护装置的吸能螺纹进行了优化设计。首先通过VPG进行了有限元模型的建立,并结合正交优化方法对吸能螺纹的参数进行了优化设计,最后在LS-DYNA中以高于法规要求碰撞速度的50 km/h对装置进行了碰撞过程的数值仿真计算,最后得到了一组优化后的吸能螺纹参数,算例表明,装置的各项指标都满足法规要求,达到了优化目的。

| Abstract: | In order to make the crank slider protective devices to meet the requirements of regulation,optimization is 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,the parameters of the absorbing thread are obtained. The crash speed in these simulations is 50km /h,which is higher than the regulatory speed. The simulation shows that all indexes could meet the regulation very well,and the effectiveness of the device is demonstrated. |
