摘　　要：分析克令吊车异响产生原因,寻找减小和消除异响的办法,利用不同的有限元建模方法进行研究,结果显示净力矩和预紧力对接触面张开距离的非线性影响最大,认为在克令吊车设计中留出足够的设计裕度以避开额定工作环境的临界值尤为重要。In order to look for the method of reducing and eliminating the crane＇s abnormal sound, different factors which may affect the craneg abnormal sound were considered. Different FEA models were used, the resu],t showed that the net torque and pre-fastening force affect the splaying distance of contact most in a non-linear way. Consequently, it is important to give e- nough surplus for design in order to avoiding the critical condition of rated working environment.
