The authors proposed a component mod synthesis method (CMS in brief) and a multiple component mode synthesis method (MCMS in brief) in the former papers on their study for analyzing the vibration of complex mechanical structures. In the present report, CPU time and accuracy of calculation by CMS and MCMS are compared with those with MSC-NASTRAN concerning the natural frequencies and the dynamic responses of two model structures. It has been made clear that the vibration of these structures can be analyzed by both CMS and MCMS with much less CPU time than by MSC-NASTRAN and with the same accuracy.
