【摘要】：本文研究的是一种磁流变液控差动行星传动装置,该装置可通过控制磁流变液的粘度来控制差动行星传动装置的传动比,从而实现对传动装置输出转速和转矩的无级调节。该装置可以实现软启动、智能调节转速和转矩,并且具有过载保护功能。 论文首先根据磁流变控制装置和差动行星传动装置的特点确定了磁流变液控差动行星传动装置的总体方案。根据总体方案,并在前人设计的基础上,设计了差动行星传动装置的结构和磁流变控制装置的初始结构。在此基础上,通过对磁流变控制装置输出特性的理论分析,建立了反应磁流变控制装置主要参数与输出扭矩关系的数学模型,并运用有限元法对数学模型进行分析求解,得到磁流变液在电场激励下的磁场分布规律和输出扭矩与结构参数之间的关系。论文在运用Ansys软件对磁流变控制装置模型进行初步分析的基础上,运用软件中的零阶算法对磁流变控制装置的结构参数进行了优化设计,优化后的磁流变控制装置不仅能传递较大的载荷,而且具有较小的体积和质量。在分析和结构优化的基础上,设计了磁流变液控行星传动装置的具体结构。论文最后对磁流变液控差动行星传动装置的无级变速控制方式进行了初步探讨和研究。
[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.
