| Abstract: | Taking the crankshaft of a low speed diesel as the object,based on the traditional dynamics calculation,the finite elements model of the crankshaft was established by UG and Ansys to calculate the fatigue of the crankshaft by the total life method.The safety factor and the total life of the crankshaft were obtained,so as to propose the structural and procedure measures to increase the strength in the dangerous areas. |
