一种新型主动轮触发方法的技术研究

Research on a New Type of Active Wheel Trigger Method

针对履带式车辆主动轮测试工况复杂且测试电路灌封于密闭壳体内,常规的触发方式无法实现有效触发的问题,提出了一种电磁感应的新型触发方法。在测试仪壳体内壁放置薄膜线圈,通过外部电磁铁通断电产生交变磁场,激励壳体内壁薄膜线圈产生脉冲触发信号。利用Ansoft Maxwell软件对交变磁信号在封闭壳体中传递的可行性进行了仿真,并进行了实验验证。仿真及实验结果表明,交变磁信号能够在封闭壳体中传递,实现主动轮内测试电路的触发。

In view of the tracked vehicle driving wheel test under complex conditions,and test circuit encapsulated to a dense shell body,conventional trigger mode can not achieve effectively triggering.A kind of electromagnetic induction of the new triggering method is proposed.A thin film coil tester shell is placed on the inner wall.An alternating magnetic field is generated by an external electromagnet which is powered on or off.A pulse trigger signal is generated by the film coil on inner wall of excitation shell.The feasibility of alternating magnetic signal transmission in the closed shell was simulated by Ansoft Maxwell software,and verified by experiments.The simulation and experimental results show that alternating magnetic signal can be transferred in the closed shell,and can trigger the driving wheel in the test circuit.
