摘要
用有限元法模拟实验过程,改变叉口或万向节的结构尺寸,计算出应力结果,然后根据多组结构尺寸的有限元应力计算结果,采用最小二乘法回归出了一套工程上实用的强度验算公式,并用电测实验证明了公式的正确性。
With the aid of finite element simluating test, the stressesof the universal joint with varied design dimensions are cal-culated. Then, based on the calcualted results of a number ofdimension groups and by using the least square method, a setof engineering-oriented formulae for strength checking aredeveloped. Results obtained by strain-gauging have proved theaccuracy of these formulae.
