Crankshaft strength analysis of shearing machine based on SolidWorks

The crankshaft stress analysis is a key link of the shearing machine design,which determines the performance of shearing machine directly.The traditional crankshaft checking is adopted for experimental method,and the calculation process is complicated.By comparing with the actual working condition,a large number of assumptions is developed with the traditional design,and there exists more errors.The influence factors such as geometry of the crankshaft,the boundary condition,and the loading are extremely complicated.In order to meet the actual condition and the crankshaft checking,the crankshaft under actual condition is modeled in three-dimensional with Solidworks2010 software,the stress of whole crankshaft is calculated by finite element method,and the crankshaft fatigue safety coefficient is checked.It is found that the maximal stress of the crankshaft is not in the middle of the contact between the crankshaft and link,but in the position between gear and crankshaft.
