| 摘要:采用PRO/E及 ANSYS Workbench软件对大流量高压供油泵多支撑轴系凸轮轴开展有限元分析。静力学分析和模态分析的结果表明:该凸轮轴的强度能够满足实际工况要求；凸轮1和凸轮2连接处变形极大，是易断裂点，在对凸轮轴进行优化设计时应重点考虑该连接处；轴颈振动对凸轮轴工作性能影响显著，应对轴颈采取减振措施。 |

| Abstract:PRO/E and ANSYS Workbench were employed to carry out finite element analysis on the multi-support camshaft system of large flow high-pressure fuel pumps. The static analysis and modal analysis show that the strength of this camshaft can meet with the working requirements, there was large deformation at the joint of camshaft 1 and camshaft 2, and it was an easy-crack point. So in the optimization design of the camshaft, the joint should be paid more attention to. As the vibration of journal has big influence on the performance of camshaft, so anti-vibration measures should be taken. |
