Abstract
With the use of hammering excitation method, the modal test of a diesel engine's body was made using LMS Test.Lab modal test and analysis system. The pole and the residue of each mode were calculated using least square complex exponential(LSCE) method. Then the stabilization diagram was built and the modal parameters of some low orders of the engine's body were provided.关键词
