摘    要
航空航天运动机构的高指向精度和长寿命由良好的润滑方式决定。MoS₂自身特殊的六方层状晶体结构表现出优异的自润滑性能，广泛应用于空间光电跟瞄转台和太阳能电池驱动装置等空间精密运动机构。然而，目前针对固体润滑膜MoS₂摩擦磨损特性的理论模型、数值仿真以及实验验证尚未完全得到系统性研究。因此，为了揭示固体润滑膜MoS₂摩擦磨损特性与工况参数之间的内在规律，基于真空环境下的销盘式摩擦磨损实验，建立了与温度、转速和载荷多变量相关的高精度摩擦系数模型，与实测结果拟合效果较好，最大相对误差仅为3.47%。将其代入至ABAQUS二次开发的Umeshmotion子程序，结合Archard理论数值计算和预测磨损深度，通过白光干涉仪测试磨损情况和失效模式，对比验证结果显示：有限元计算与实测磨损深度之间的相对误差为5.26%，说明本工作针对多工况下固体润滑膜MoS₂摩擦磨损特性研究方法的有效性和可靠性，其可为空间精密运动机构的寿命和精度预测提供重要参考和理论指导。

Abstract
The high pointing accuracy and long service life of aerospace motion mechanisms are determined by a good lubrication method. The special hexagonal layered crystal structure of MoS₂ exhibits excellent self-lubricating properties and is widely used in space precision motion mechanisms such as space photoelectric tracking platforms and solar cell drive devices. However, at present, systematic research on the theoretical models, numerical simulations, and experimental validations regarding the friction and wear characteristics of the solid lubricant film MoS₂ has not yet been fully conducted. Therefore, in order to reveal the intrinsic relationship between the friction and wear characteristics of the solid lubricant film MoS₂ and the operating parameters, based on the pin-disc friction and wear experiments under a vacuum environment, a high-precision friction coefficient model related to multiple variables such as temperature, rotational speed and load was established. The maximum relative error of the fitting effect with the measured results was only 3.47%. By substituting it into the Umeshmotion subroutine of the ABAQUS secondary development, combining the Archard theory for numerical calculation and prediction of wear depth, testing the wear condition and failure mode through white light interferometer, it was compared and verified that the relative error between the finite element calculation and the measured wear depth was 5.26%, indicating that the research method for the friction and wear characteristics of solid lubricant film MoS₂ under multiple working conditions proposed in this paper was effective and reliable. It could provide important reference and theoretical guidance for the life and accuracy of spatial precision motion mechanisms.
