摘要/Abstract

摘要： 针对一种新型汽车电泳涂装输送机构，提出一种表征并/混联式输送机构输入输出端之间的运动/力传递效率的分析评价方法。首先采用旋量形式导出输送机构的运动学和动力学，再根据旋量的Klein型即李代数e(3)的双线性形式，建立了以输送机构末端执行器的瞬时运动功率与输入端瞬时运动功率的比值作为表征机构输入输出的运动/力瞬时传递效率的瞬态分析评价指标。基于所提出的分析评价方法，得出机构在三种典型期望运动轨迹下从输入端到输出端的运动/力瞬时传递效率随时间变化的曲线，并求得其运动/力平均传递效率。最后利用MATLAB软件对机构进行实例仿真，仿真结果表明了评价指标的合理性和有效性。

Abstract: For motion/force transmission efficiency from the inputs to the outputs of a novel mechanism for automobile electro-coating conveying, an analysis and evaluation method was proposed. Firstly, the kinematics and dynamics of conveying mechanism were derived by screw form. According to the Klein form of the screw, namely a bilinear symmetric form of the Lie algebra e(3), the transient analysis and evaluation index of the input/output motion / force instantaneous transfer efficiency was presented ,which was based on the ratio of the instantaneous powers of the end effector of the conveying mechanism and the instantaneous input powers of the input terminal. Furthermore, on the basis of the proposed evaluation method, the time varying curve of the instantaneous transfer efficiency of mechanism motion / force were obtained, and the average transfer efficiency of the motion / force was obtained. Finally, the simulations of the mechanism were carried out by using MATLAB software. The simulation results show that the evaluation index is reasonable and effective.

Key words: performance index, screw theory, conveying mechanism, motion/force transmission efficiency
