平滑运动 meaning in English

smooth motion

Since frictional vibration damages a mechanical system ’ s performances when the system works at a low velocity , efficient antifriction techniques are the key tasks that have been seeking after all along
一个机械系统低速运行时,影响性能的一个重要问题就是摩擦振动的存在。学者们在不断的探寻高效的润滑技术来减小摩擦,实现机械系统的低速平滑运动。
In order to realize smooth movement of mechanical system at a low velocity , the following work investigates new types of linear ultrasonic motors and antifriction technique by superposing the motor ’ s elliptical vibrating motion at the friction interface to change frictional characteristics , produce ultrasonic lubricant effect and realize active control of friction force
本文研究新型超声波马达,利用其产生于摩擦界面的椭圆轨迹超声振动引起的润滑效应和摩擦接触行为的改变来减小摩擦力的大小,完成对摩擦力的主动控制,实现机械系统的低速平滑运动。
