摘　　要：根据结构动力学分析的有限元方法，计算出了高压装置一次压缩机管系的固有频率和强迫振动的响应位移值，与实测结果作了比较，模拟出原管系的支承刚度。通过调整支承位置和支承刚度的方法进行管系减振方案设计，经过反复计算和对比分析，得到了原管系减振的最佳改造方案，并对其实施了改造。According to the finite element method of structural dynamics,the free frequency and response displacement of enforced vibration are given for the high pressure inlet compression engine pipe system. The analysis results are compared with measured results,then the support stiffness is determined. By varying the support points and the stiffness of the pipe system, the calculation process is repeated until the best modified version of decrease in vibrations is obtained.Finally,the initial pipe system has been modified.
