[Abstract]:Combined with the structural design of hydraulic pipe grab machine, based on virtual prototyping technology, using 3D design software Solidworks and virtual prototype simulation software ADAMS as the platform, the virtual prototype simulation model is studied and established, and the kinematics trajectory analysis of hydraulic pipe grab machine is carried out. The mathematical structure model of pipe grab machine is established by D-H method, and the theoretical value of several important locus position of pipe grab machine is calculated and compared with the simulation value. The rigid-flexible coupling model analysis method of virtual prototype is studied, and the rigid-flexible coupling model of hydraulic pipe grab machine is established. In order to explore the key technology of virtual prototyping used in the design process of the product, this paper mainly studies the following aspects. First, combined with the structure design of the hydraulic pipe grab machine, The principle and motion characteristics of hydraulic tubing mechanism are briefly analyzed, and the 3D model of hydraulic pipe grab machine is established by using 3D solid design software Solidworks. The 3D solid model is introduced into the simulation analysis software ADAMS to analyze the kinematics of the hydraulic pipe grab machine. The plane motion track of the hydraulic pipe grab machine is obtained, and the working range of the pipe grab machine is grasped. In order to verify the accuracy of the simulation analysis, the mathematical model of the pipe grab machine is analyzed by D-H method. The movement position of the grab hand of the hydraulic pipe grab machine is obtained by matrix transformation, and the trajectory position of the pipe grab machine under several special working conditions is calculated. And compared with the simulation results. Finally, combined with the simulation software in kinematics and dynamics analysis of the theoretical basis, The dynamic analysis of the virtual prototype model of hydraulic pipe grab machine under the condition of rigid and flexible coupling is carried out. The simulation and analysis of hydraulic pipe grab machine are further discussed in the field of engineering by computer simulation. The rigid-flexible coupling analysis based on ADAMS is the first attempt of hydraulic pipe grab machine in domestic literature. The research results can provide a reference for the dynamic design of this kind of machinery.
