Crustal movement is a key factor affecting water cycle and related land surface processes. In this paper, the principle of a class of crustal movement simulation system (CMSS) is introduced. The CMSS proposed in this study is composed of twelve sets of four-legged parallel manipulator with three degrees of freedom. The structure of the parallel manipulator with actuation redundancy is analyzed. In...
Tip deflection and vibration have a large impact on the manipulator operation safety, and hybrid structure flexible manipulator has a larger workspace and more flexibility. In this paper, a new modeling scheme for a hybrid structure flexible manipulator is proposed. In the proposed scheme, the joint variables of hybrid structure flexible manipulator are divided in rigid joint angle and small joint...
This paper presents an extended kinematics and dynamics of the articulated tracked vehicles (ATV) used in many applications. The velocity of the front and the rear vehicle are firstly analysed and the kinematics of ATV is built, according to which the steer radius and the track velocity can be obtained. Then we analyse the force and moment acting on the ATV running on the firm ground and the soft...
