摘要
Abstract
Based on the analysis and research of the cracking phenomenon of servo-valve's spring tube in the random vibration process of a certain type of servo mechanism,it is determined that the spring tube cracking is caused by the coupling between the natural frequency of shaking table and fixture and the nature frequency of the first order of the servo valve armature component,which causes the servo-valve's spring tube resonance and causes the amplification of vibration magnitude.In order to analyze the influence of different shaking tables,different vibration fixtures and different installation channels under the same machine on the servo-valve's spring tube under random vibration,three comparative tests were carried out respectively.Through the comparative analysis of the test,it is found that different conditions have an impact on the vibration magnitude of the servo-valve's spring tube.When the 16-ton vibration test bench,random vibration fixture and the machine A channel vibrate in the Y direction of a servo mechanism,the vibration magnitude has a amplification effect,which is easy to cause the resonance of the spring tube and cause fatigue cracking.关键词
