空気圧シリンダのメータアウト速度制御時のスティックスリップ現象

第2報スティックスリップ発生条件

抄録

Pneumatic cylinders may not achieve steady motion when driven at low speed because of the stick-slip effect. However, an effective means to assess the possibility of stick-slip occurrence in pneumatic cylinders has not been presented. Therefore, it is still unknown under what conditions stick-slip occurs. In the first report, it is shown that stick-slip can be described with good accuracy by simulation. However, there are many parameters in the simulation of stick-slip, that it is not easy to clarify the occurrence conditions of stick-slip and the influence of each of the parameters.
Therefore, in this report, the occurrence conditions of stick-slip are studied analytically using dimensionless parameters. It is found that the occurrence conditions of stick-slip in pneumatic cylinders can be expressed in function of two dimensionless parameters. The analysis is validated through experiments shown in the first report. The influence of each parameter on the occurrence of stick-slip is clarified.
