摘要考虑行星滚柱丝杠副传动间隙、啮合面接触变形、丝杠扭转与拉压变形、加工误差、载荷分布、摩擦力及惯量等因素，运用键合图理论建立行星滚柱丝杠副动态特性分析模型，推导其状态方程。引入功率结型结构描述传动间隙引起的螺纹啮合面间接触力、阻尼力非线性分段特性，用LuGre模型反映啮合面摩擦力对行星滚柱丝杠副动态特性影响。以一组行星滚柱丝杠副参数为例，将其阶跃速度响应结果与Adams仿真结果进行对比，验证模型正确性。分别研究丝杠转速、滑滚比对摩擦力响应特性影响及传动间隙、加工误差对刚度特性影响。分析结果有助于提高行星滚柱丝杠副动态精度及工作稳定性。

Abstract：Based on bond graph theory, a dynamic analysis model of planetary roller screw mechanism is presented, in which transmission clearances, contact deformations of threads, torsion and compression deformation of screw, machining errors, load distribution of threads, friction and inertias are taken into consideration. Meanwhile, state equations of the model are given. In this model, to introduce the nonlinear and section properties of contact force and damping force caused by transmission clearances between threads surfaces, the concept of switched power junctions using clearance as the signal is employed, and the influence of friction on dynamic characteristics of planetary roller screw mechanism is considered based on the LuGre model. Taking a planetary roller screw mechanism as the example, the step response of velocity is compared with the result from Adams simulation, which verifies the effectiveness of the model. Then, The influence of rotation speeds of screw and slide roll ratios on friction response characteristics, and the influence of transmission clearances and machining errors on stiffness characteristics are investigated. The results can help to improve the dynamic accuracy and stability of planetary roller screw mechanisms.
