| 摘要: |
| 以行星滚柱丝杠为研究对象,针对伺服控制所关注的传动间隙和机构刚度2个非线性因素,建立了基于行星滚柱丝杠的摆动摇臂式弹载伺服系统传动机构非线性数学模型。重点建立了该传动机构的传动间隙模型、间隙动态计算模型及变刚度模型,结合行星滚柱丝杠运动学模型和摆动摇臂式传动机构传动模型,最终得到行星滚柱丝杠传动机构非线性数学模型。据此进行了带载条件下的伺服机构性能仿真,分析了间隙与刚度对伺服机构性能的影响,并使用性能向量法对不同传动间隙和组件刚度的影响进行了评价总结。 |

| Abstract: |
| In this paper, the planetary roller screw (PRS) is studied through focusing on the nonlinear factors of clearance and stiffness to constitute a nonlinear model of a PRS based transmission. By combining the focally constructed models of clearances, dynamic calculation of clearance and variable stiffness with those of PRS mechanism and transmission, the proposed nonlinear model is established. After simulating the effects of overall clearance and compliance, performance vector is applied to collating effects of various clearances and compliances across the mechanism for further analysis. |
