摘要
研究了电梯行业的安全标准和电梯制动器型式试验细则,总结出了电梯制动器的试验工况,并建立了试验工况下制动器的动力学模型。针对在电梯整机上进行电梯制动器的型式试验存在的缺陷,基于对试验工况下制动器动力学模型的分析,提出了实施电梯制动器性能检测的新方法,并设计了性能检测试验样机。建立了试验样机中电机转矩加载的数学模型,基于能量补偿的方法建立了电机的加载算法,从而保证了电梯制动器在试验样机上和在电梯整机系统上的制动规律相一致。
By studying the elevator industry safety standards and rules for type test of lift,the authors acquired elevator brake test conditions and established a dynamics model of the brake. A new method to implement the elevator brake performance testing was put forward. A performance testing prototype was designed based on the new method. A mathematical model and algorithm of load torque were established, which ensures that the elevator braking law in the testing machine and lift is consistent.
