Abstract: | In order to improve the engineering design ability of crankshaft prototype,the curve of engine active torque cycle is obtained by build a test model of engine crankshaft performance using AMESim software.The periodic active torque is dynamically loaded into each crank pin in the finite element software ADINA,the stress cloud diagram and maximum stress of crankshaft are obtained.The six free modes are calculated,and the lowest natural frequency is beyond the excitation frequency,which meets the design requirements of avoiding resonance.The 1000-hour mixed load test and 300-hour cold and thermal shock test are completed on the engine platform.The results show that the wear amount of each journal is less than 1mm,and there is no obvious deformation or crack,no gluing or plastic deformation on the surface of the journal. |
