形状记忆合金控制的圆筒式磁流变液无级传动
Cylindrical Magnetorheological Fluid Stepless Transmission Controlled by Shape Memory Alloy
摘要
Abstract
Based on the shape memory effect of shape memory alloy under thermal effect and the rheological behavior of magnetorheological fluid,the relationships of the shape memory alloy temperature detect switch's output displacement with the temperature,the geometric parameters,the material parameters and the operating load was established. The shape memory alloy temperature detect switch was used to control the current that induced magnetic field. The Herschel-Bulkley model was used to describe the constitutive characteristics of magnetorheological fluid subjected to an applied magnetic field to derive the relationships of the magnetorheological fluid transmission torque with the magnetic field parameters, the magnetorheological fluid material parameters, the size parameters and the motion parameters. The results indicate that the output displacement of the shape memory alloy temperature detect switch can change rapidly with the temperature. The torque transmitted by magnetorheological fluid goes up rapidly with the increase of the applied magnetic field strength and the output angular velocity can be adjusted continuously by the air temperature from radiator.关键词
