一、问题的由来几种红外导弹涡轮电机的切换电路,经常碰到超差问题,以致于振动试验、温度试验需要反复进行,浪费人力、财力、拖延生产周期。如何加以改进,设计出性能参数合乎要求,而生产调试又比较简单的产品,正是本文所要讨论的中心内容。 First, the origin of the problem Several types of infrared missile turbo-motor switching circuit often encounter ultra-poor problems, so that the vibration test, the temperature test needs to be repeated, a waste of manpower and financial resources, delay the production cycle. How to improve, design performance parameters to meet the requirements, and production and commissioning of relatively simple products, it is the center of this article to be discussed.
