减少振动高速凸轮廓线修正的简易方法

A Simple procedure for Modifying High-Speed Cam profiles for Vibration Reduction

凸轮从动件的多余振动将造成系统的力、噪音、磨损和工作成本增加,本文采用凸轮轮廓输入成形来减少振动,输入成形是一种实际的时间控制算法,它是为计算机控制器开发的,为了应用凸轮设计概念,必须建立某些修正算法。采用可变的工作速度和从动件动力学建造一试验装置来检验高速输入外形凸轮轮廓的效能。试验结果表明本文推荐的解决方法是有用的。

Unwanted vibration in cam-follower systems causes increased forces, noise, wear, and operating costs. This paper investigates the use of input shaping on cam profiles to reduce vibration. Input shaping is a real-time command modification algorithm developed for computer-controlled machines. In order to apply the concept to cam design, some modifications to the algorithm must be made. To test the validity of highspeed input-shaped cam profiles, an experimental apparatus was constructed with variable operating speeds and follower dynamics. The experimental results demonstrate the effectiveness of the proposed solution.
