[Abstract]:In this paper, a magnetorheological fluid controlled differential planetary transmission device is studied. This device can control the transmission ratio of the differential planetary transmission by controlling the viscosity of the magnetorheological fluid, so as to realize the stepless adjustment of the output speed and torque of the transmission device. This device can realize soft start, adjust speed and torque intelligently, and have overload protection function. Firstly, according to the characteristics of the magnetorheological control device and differential planetary transmission, the overall scheme of the magnetorheological fluid controlled differential planetary transmission is determined. According to the overall scheme and on the basis of previous designs, the structure of differential planetary transmission and the initial structure of magnetorheological control device are designed. On this basis, through the theoretical analysis of the output characteristics of the magnetorheological control device, the mathematical model of the relationship between the main parameters and the output torque of the reactive magnetorheological control device is established, and the mathematical model is analyzed and solved by the finite element method. The magnetic field distribution of magnetorheological fluid under electric field excitation and the relationship between output torque and structural parameters are obtained. Based on the preliminary analysis of the magnetorheological control device model by using the Ansys software, the structure parameters of the magnetorheological control device are optimized by using the zero-order algorithm in the software, and the structure parameters of the magnetorheological control device are optimized by the zero-order algorithm. The optimized magnetorheological control device can not only transfer large loads, but also have smaller volume and mass. On the basis of analysis and structure optimization, the structure of magnetorheological liquid-controlled planetary transmission is designed. At last, the variable speed control mode of magnetorheological fluid-controlled differential planetary transmission is discussed and studied.
