摘要
将两个柔性铰链与两个等截面弹性悬臂梁进行组合,设计出一种新型的摩擦传感器,该传感器消除了传统摩擦传感器组合构件间的反向间隙和摩擦的影响,实现了速度反向区摩擦因数的连续检测。应用结构力学理论推导得出传感器解耦的表达式,进而对传感器的结构进行解耦优化设计,消除了正压力和摩擦力的互干扰,并给出了传感器的设计流程图。设计实例的计算结果表明了所提出设计方法的有效性。
A new type frictional transducer was designed by assembling two flexure hinges and two uniform cantilever beams. The influence of friction and reversal clearance which existed in the parts of traditional sensors were avoided, and the continuous measure of friction factor was realized. The expression of interaction between normal force and friction was deduced on theory of structural mechanics. The structure of transducer was optimized if the part sizes of the sensor were given, and therefore the coupling of normal force and friction was eliminated. The flow chart for design the sensor was presented. The results of simulation prove the availability of the sensor.
