【Abstract】 Different from the traditional analysis of moving mass-structrue interation, the vi-brational coupled differential equation of flexible beams combined with a high speed moving masson it is presented, in which the rigid movement of moving mass is not prescribed beforehand, namely, Timoshenko Paradox is taken into consideration. The numerical integration formulation is formed to determine the dynamic response of the system according to the characteristics of the vibrational equations. Illustrative example verifies the validity of the present method.更多还原
