摘要
本文针对中小型计算机内存少的特点,采用有限元分析中的新方法——子结构法,将摇臂壳体分为两块进行耦合分析。该法经电测实验证明是合理的。使得用中小型计算机计算较复杂构件成为可能。
Because there is not enough capacity of memory in microcomputer, a new method of the finite element analysis the sut-structure method is applied to divide it into two when ranging arm is calculated, and it is reasonable that above
method have been proved by means of testing. It not only supplies a new way
for the finite element calculation of complex structure, but makes it possibile to calculate complex structure by means of microcomputer.
