【Abstract】 The steady state response is one of the important contents in dynamics of linear controlled multibody system. The transfer matrix method for linear controlled multibody system is established, to compute its steady state response’ and two simple linear controlled multibody systems are taken as examples.The extended transfer matrices and extended transfer equations of lumped masses and spring-damping hinges on which the control forces act are formed. The computing results got by Newton method and transfer matrix method for linear controlled multibody system, are compared. The examples show that the method can be used to analyze the dynamics of linear controlled multibody system, and entirely keep all advantages of the traditional transfer matrix method.更多还原
