研究了用外加电压法对三氧化二铝／黄铜摩擦副的低速滑动摩擦行为进行主动控制的技术．结果表明：通过合理选择控制算法中的步长参数，能使摩擦系数的波动幅度得到有效控制；摩擦系数预定目标值与实测值之间的误差可控制在 ３％ 之内，即摩擦系统能够达到较高的控制精度．由初始值到达目标值所需过渡过程的长短与控制算法中的步长参数有关，试验中稳定系统的过渡过程约为 １０～３０ ｍ ｉｎ．上述结果显示，用外加电场的方法来主动控制摩擦是可行的
The technology of active control of the low speed sliding friction behavior of aluminum oxide / brass friction pairs by applying voltage method was studied. The results show that the fluctuation range of friction coefficient can be effectively controlled by selecting the step parameters in the control algorithm reasonably. The error between the predicted target value and the measured value of the friction coefficient can be controlled within 3%, that is, the friction system can reach Higher control accuracy. The length of the transition required to reach the target value from the initial value is related to the step parameter in the control algorithm. The transition of the stable system in the experiment is about 10 ~ 30 mins. The above results show that it is feasible to control the friction by using the electric field method
