为解决曲柄滑块机构的间隙问题,提高曲柄滑块机构的位置精度。从曲柄滑块机构的简单机理出发建立其简化模型,再利用传感器去测量曲柄滑块机构各构件的运动物理量;然后,利用参数辨识法对曲柄滑块机构的系统参数进行辨识;最后,建立含间隙的曲柄滑块机构模型并进行仿真分析。对比结果表明,利用参数辨识法建立的模型具有较高的准确性且建模过程简单,为复杂非线性机电系统的建模提供了新的思路。

In order to solve the problem of the clearance on the slider-crank mechanism and improve the position precision of the slider-crank mechanism. Starting from the simple mechanism of slider-crank mechanism, the simplified model is established. By using the sensor to measure the movement parameters of artifacts of the slider-crank mechanism, then system parameters of the slider-crank mechanism are identified by using the method of parameter identification. Finally, the model of the slider-crank mechanism with clearance is established and the simulation analysis is carried out. The comparison resu...
