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.
以行星滾柱絲槓為研究對象,針對伺服控製所關註的傳動間隙和機構剛度2箇非線性因素,建立瞭基于行星滾柱絲槓的襬動搖臂式彈載伺服繫統傳動機構非線性數學模型. 重點建立瞭該傳動機構的傳動間隙模型、間隙動態計算模型及變剛度模型,結閤行星滾柱絲槓運動學模型和襬動搖臂式傳動機構傳動模型,最終得到行星滾柱絲槓傳動機構非線性數學模型. 據此進行瞭帶載條件下的伺服機構性能倣真,分析瞭間隙與剛度對伺服機構性能的影響,併使用性能嚮量法對不同傳動間隙和組件剛度的影響進行瞭評價總結.

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 con?structed 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.
