Title Transfer Matrix Method of Multibody System and Its Applications to Vehicle Dynamics
Abstract
Numerous complex mechanical systems have appeared in the field ,such as,machinery ,
aeronautics,robot .Therefore, Multibody system dynamics which mainly study the
complex mechanical systems is an important branch in the field of the modern
mechanics now.Classical transfer matrix method can’t provide a simple and
effective method to solve a complex multibody system.Because the order of the
system matrix involved is rather high for complex system ,which results in huge
computational time.The new method for multibody system dynamics has the advantages
as follows:without the global dynamics equations of system ,high programming ,low
order of system matrix and high computational efficiency ,etc. In this paper,
simplifing and modeling the vehicle system,using the transfer matrix method of
multibody system analysis the vehicle system and figure out the computation for
state vector ,nature frequencies and normal mode .
Keywords matrix method of multibody system and its applications computation for
state vector nature frequencies normal mode
