本文应用瞬变振动理论统一地讨论了后座机构的安全与可靠作用条件,提出冲击响应谱规范法(Shock Response Spectrum Spesificationmethod 筒称 SRSS法),给出按要求的安全性及作用可靠性制定安全谱规范与可靠作用谱规范的方法。指出冲击响应谱规范的两个实际用途:一是定义两个谱规范所包的区域为机构可靠区,给出在可靠区上进行机构设计的方法;二是在检验方面给出用等效半正弦加速度脉冲冲击响应谱局部复盖安全谱规范的方法建立新的检验规范。 本文指出华西列夫安全条件式并非总是保守的,对低于临界频率的机构可能存在着风险。
In this paper, the transient vibration theory is used to discuss the safety and reliability of the rear seat mechanism. The Shock Response Spectrum Spearmethod (SRSS) method is proposed. The safety and reliability of the required safety and reliability are also given. Spectral and Reliable Spectral Methods. The two practical applications of the shock response spectrum specification are pointed out: one is to define the area covered by the two spectral specifications as the reliable area, the method to design the mechanism in the reliable area is given; the other is to give the equivalent half Sinusoidal acceleration impulse response spectrum Local coverage safety spectrum specification method to establish a new test specification. This paper points out that the Huaxiluofu safety condition is not always conservative, and there may be risks to the institutions below the critical frequency.
