Abstract
Virtual triaxial shaker testing is helpful to optimize the test plan and avoid over-testing issues.The transfer function matrix of the test specimen mounted on a triaxial shaker is one of the required system dynamic characteristics for conducting a triaxial virtual shaker test.In view of the above problem,this paper studied the construction method for the transfer function matrix of the specimen on the triaxial vibration system,and proposed a computation method of the transfer function of the specimen.The finite element(FE)model of the specimen was established and corrected.The transmission characteristic of the triaxial vibration system was measured.The transfer function of the test specimen was calculated by us-ing FE model and measured data.The result can be used to conduct virtual triaxial shaker testing.关键词
