【Abstract】 Take the mechanical error of mechanism into consideration and let the mechanical error to be regarded as a random factor and take the manufacturing cost as the target of optimization design,the optimization design was carried out on errors of structural parameters.The tolerances of designing parameters were optimally distributed,the overall manufacturing cost of mechanism was lowered,and thus the contradiction(bet)ween function of design and economy was nicely settled.更多还原
