挤压-剪切复合模式下磁流变液传动装置传动性能研究
Research on Transmission Performance of Magnetorheological Fluid Transmission Device Under Squeeze-shear Compound Mode
摘要
Abstract
The magnetorheological(MR)fluid transmission device offers advantages such as high controllability,rapid response,and low power consumption.By incorporating the squeeze-strengthening effect,the power of the transmission device can be significantly enhanced.Through analyzing the magnetic energy of the MR fluid under squeeze-shear compound mode,the expression for the torque transmission of MR fluid under compound mode is derived.It is found that reduction in particle distance induced by squeeze leads to an increase in yield stress.A novel compound mode transmission method based on hydraulic squeezing is proposed,and a disc-type transmission device with axial pressure regulation capability is designed,of which the transmission performance is tested.The results show that under an excitation current of 2 A and a squeeze stress of 306 kPa,the output torque of the device reaches 174 N·m,representing an 85%improvement compared to the shear mode,with a transmission efficiency of 87%and a dynamic response time of 372 ms.The squeeze effect enhances the transmission torque of the MR fluid device without affecting the zero-field torque,static characteristics,or dynamic response time.This study provides theoretical and technical solutions for the design of high-power-density MR transmission devices.关键词
