| Abstract: | To Pro/E as a platform,equations based on the establishment of precision gear pump gear shaft model,and to vibration and me-chanical finite element theory,the establishment of the gear shaft finite element model, use of Pro/E integrated environmental Pro/MECHAN-ICA its medal analysis. The former 4 ranks of natural frequencies and model shapes were caculated, so it provided a theoretic basis for the de-sign of gear shaft and the foundation for calculation of dynamic response;in order to improve the dynamic characteristics of gear pump and a-void resonance,it provide a method for improving the reliability of its wrok to design. |
