摘　　要：在汽车中 ,常常采用特制直流继电器控制小功率直流电动机正、反转。本文研究继电器在该种使用类型下的电寿命试验条件。即小功率直流电动机为负载时 ,继电器闭合与分断时电压与电流的条件。为了实现该条件 ,设计了试验主回路。通过MATLAB仿真和实际应用 ,验证该试验回路与实际情况基本符合。We often use special DC relay to control low powered DC motor in cars.This paper researches electric life testing condition of relay used by vehicles.In other words,the condition of voltage and loop current of relay operating and closing when load is low powered DC motor.In order to realize the condition,we design the main circuit to simulate starting and stopping of motor.Through emulating by MATLAB and application,the testing circuit matches with the real condition.
