摘要
内曲线柱塞马达中柱塞受力导致滚柱与柱塞接触面之间发生硬性接触,造成摩擦磨损,降低了马达工作性能与使用寿命。为减小内曲线柱塞马达柱塞的磨损,在柱塞上开应力变形孔释放应力能量,达到减小变形的目的。利用ANSYS-Workbench进行仿真,得到柱塞滚柱面的变形分布,并分析了应力变形孔的宽度和位置对变形的影响。结果表明:应力变形孔可以改变柱塞应力分布,从而减小滚柱面关键部位的变形,并且随着应力变形孔宽度和位置的变化,滚柱面上不同位置的变形变化规律也有差异,因此存在着相对最优的宽度与位置。
The hydraulic pressure on the plunger of inner curve hydraulic motor leads to the hard contact between the contact surfaces, the cause of friction and wear, so the performance and service life of motor can also be reduced. In order to reduce the deformation of inner curve hydraulic motor plunger, the stress deformation hole on the Plunger is established, Using ANSYS as the simulation software to get the deformation distribution of roller surface, we analyze the influence of the width and location of the hole on the deformation of roller surface. The results show that, the stress deformation hole can be able to change the stress distribution of the plunger and reduce the deformation of the key position of roller surface; different width and location parameters of the hole can cause the variation of the deformation, and the variation of different positions on roller surface is not the same, there is a relatively optimal width and location of the hole.
