制动器

Based on dynamic test data, using curve fitting and optimum method, three dynamic empirical model are developed according to the principle of minimizing errors, they are trilinear hysteresis model, variable linear hysteresis model and variable nonlinear hysteresis model.

对系统辩识模型作出了改进，把准静态特性的幂函数乘积模型与辩识模型相结合，形成了制动器的理论分析模型。

The object of this paper is the ZPT-650B disc brake of China Coal Research Institute Shanghai Branch, a three-dimensional transient thermal and stress coupled FEM model is established which confirms to the trim size of the disk as well as regard the coupled problem.

本文以煤炭科学研究总院上海分院的ZPT-650B防爆型盘式制动器为对象，按照制动盘的实际尺寸，充分考虑了制动盘的温度场和应力场耦合问题，建立了三维循环对称有限元模型。

Currently most domestic break-test-plateform adopt the liquid-pressure-servo technique, which possesses the advantages of higher frequency-response and higher controlling exactness, but in the same time , the disadvantages of higher cost, variation of function with the change of oil viscousness produced by the fluctuation of temperature.

目前，国内的制动器试验台大多采用的是液压伺服控制，这种控制具有响应频率高、控制精度高等优点，主要缺点是系统成本高、油液粘度随温度变化引起工作性能的变化、且液压系统对油液的污染比较敏感，必须要有良好的保护和过滤措施。
