某型雷达传动系统异响机理分析

Research on Abnormal Sound of a Radar Drive System

传动系统是雷达的关键系统,传动系统的异常及发生故障的前兆往往表现为出现异常响声。文中对某型雷达传动系统的异响进行了机理分析。通过对传动部件的排查、伺服控制参数的调整以及对整个系统的听觉、视觉和触觉感受,并结合相关振动理论,利用能量累积和释放的原理解释了异常响声现象,并得到相关验证。研究成果和分析方法对解决其他类似传动系统的异响问题具有参考价值。

Drive system is a key system of radar. Abnormal sound is usually the forewarning of fault or abnormity of drive system. This paper carries out mechanical analysis for the abnormal sound of a radar drive system.Through checking the drive parts,adjusting the servo system parameters and feeling the whole system by ears,eyes and fingers,the reason of abnormal sound is given according to related vibration theory and the principle of energy accumulation and release. Verification is also carried out. The result and method of this paper can provide reference for solving the abnormal sound problem of similar drive system.
