【摘要】 本文应用空间杆系有限单元法,编制了程序CDP(Coculation ofDynamic Paraments)系统。对HH1012一类半承载式微型车车架的固有频率和振型进行了计算和实验验证,取得了较好的结果。此外,在计算过程中,由於采用了批处理文件控制各个独立小程序走向,在保证较高的计算精度的同时,可降低对计算机容量的要求。更多还原

【Abstract】 In this paper,the CDP system was programmed and the computer simulationof natural frequencies and vibrational modes of semi-integral truck frames suchat HH1012 model was presented,by the finite element method of space rods sys-tem. It was verified by the model analysis experiment. Bocause batch process filewas used to control the executed sequence of those small independing programs,so that, the required computer memory capacity was reduced, while the desirdeaceuracy was kept.更多还原
