摘要：'The ride dynamic characteristics of a typical medium weight, high speed military-tracked vehicle for negotiating rough cross-counlry terrain have been studied. The vehicle is modelled using finite element simulation method with beam and shell elements. An eigenvalue analysis has been done to estimate natural modes ofNibration of the vehicle. The dynamic response of certain salient locations is obtained by carrying out a transient dynamic analysis using implicit Newmark beta method. A constant forwar vehicle speed and non-deformable sinusoidal terrain profile are assumed.
