| 摘 要： | 简要论述了双协调动态子结构法的动力学原理,并以Q485柴油机的曲轴飞轮系统为研究对象计算了系统扭转振动的模态参数。对BCDSP双协调动态子结构计算程序进行了重要修改,使其能有效地适用于小型计算机或微机。为了比较,对整体结构还用有限元法和试验模态分析识别模态参数,与本法所得结果相吻合。

| Abstract: | Dynamics of bi-consistent dynamic substructure procedure (BCDSP) is briefly dealt with and modal parameters in torsional vibration of crankshaft-flywheel system calculated with special reference to Diesel Q485. BCDSP is modified to be effectively operated on minicomputer or microcomputer. For comparison, modal parameters are also identified with finite element method and test modal analysis respectively and results thus obtained are in good agreement. |
