Abstract

This paper concerns about subsystem synthesis method of multi-body tracked vehicle systems which consist of several subsystems. A complex multi-body tracked vehicle system can be divided into several subsystems using subsystem synthesis method. A subsystem can be independently analyzed with a virtual massless reference body. Virtual massless reference body has information of position, velocity and acceleration for base body. But virtual reference body has not mass and force. In subsystem synthesis method, position, velocity and acceleration analyses of the subsystems are carried out in the forward recursive fashion. For overall multi-body tracked vehicle system analysis, subsystems can be synthesized to the base body with effective matrix and vector from the virtual massless reference body of each subsystem. Using these effective matrix and vector of subsystems, equations of motion with base body can be solved independently. After then equations of motion of each subsystem can be solved using results of base body. Advantages of proposed method are investigated with regard to computational efficiency and solution accuracy. In order to show the effectiveness of this method, a multi-body tracked vehicle of seafloor massive sulfide has been analyzed. method.
