应用整体传递矩阵法对某型发动机转子—支承—机匣—安装节系统进行了整机临界转速及应变能分布的计算与分析,并与整机振动的测试结果进行了对比分析,其计算结果与测试结果基本一致。
The whole transfer matrix method is used to calculate and analyze the critical speed and strain energy distribution of a certain type of engine rotor-bearing-casing-mounting joint system. The results are compared with the test results of the whole machine vibration. The calculation results And the test results are basically the same.
