The power loss characteristics of slipper pair in an axial piston pump considering the thermoelastohydrodynamic deformation are investigated based on a transient power loss model. The simulation results indicate that the leakage power loss of the slipper pair increases with increasing the thermoelastohydrodynamic deformation. The viscous friction power loss decreases with an increase in the thermoelastohydrodynamic pressure. The viscous friction becomes sufficiently large under the influence of slipper surface roughness that it leads to an increase in viscous friction power loss. The pump displacement decreases with increasing the leakage rate and results in higher leakage power loss and higher friction power loss. To achieve minimum power loss in the slipper, an objective optimization study using Newton's method is applied to calculate structural parameters such as slipper inner diameter, slipper outer diameter, and orifice diameter. The proposed structural parameter optimization can be used as theoretical evidence for slipper pair design.

考虑热弹性流体动力变形的轴向柱塞泵滑靴副功率损失特性分析

基于瞬态功率损失模型，研究了考虑热弹流体动力变形的轴向柱塞泵中的滑块对的功率损失特性。仿真结果表明，拖鞋的泄漏功率损失随着热弹流体力学变形的增加而增加。粘摩擦功率损耗随热弹流体动压的增加而减小。粘滞摩擦在拖鞋表面粗糙度的影响下变得足够大，从而导致粘滞摩擦力损​​失的增加。泵排量随着泄漏率的增加而减小，并导致更高的泄漏功率损耗和更高的摩擦功率损耗。为了使拖鞋的功率损耗最小，使​​用牛顿 s方法用于计算结构参数，例如拖鞋内径，拖鞋外径和孔口直径。所提出的结构参数优化可作为拖鞋对设计的理论依据。
