| 摘 要： | 针对弹子加压装置,采用ANSYS软件对弹子与弹子槽的接触状态进行了有限元仿真分析.有限元仿真计算结果与试验结果均表明:当载荷达到40 kN时,最大接触变形可达40μm,弹子盘的最大接触应力为1.4GPa,弹子的最大接触应力为1.32 GPa,均在弹性范围内.对于弹子与弹子盘的接触,采用经典的赫兹接触模型的计算结果与有限元仿真计算结果和实测结果存在较大的偏差,说明经典赫兹接触模型并不适用于弹子和弹子槽的接触分析,应对其进行修正.

| Abstract: | In this paper, the contact state of marble and marbles disk slot in marble-marbles disk pressure mechanism with the finite element analysis ANSYS software is analyzed. The results of finite element analysis and experimental show that, when the load reaches 40 kN, the maximum contact deformation is 40 μm, the maximum contact stress in marble disk slot is 1.4 GPa, the maximum contact stress in marbles is 1.32 GPa, and there are no plastic deformation. The experiment results of the classic Hertz model for the contact of marble and marbles disk reveals a large deviation in contrast to the results of finite element analysis, indicating that classical Hertz contact model cannot fit to the contact analysis of marble and marbles disk slot, and need to be revised. |
