Abstract

The integrated transmission system of military armored vehicle is a kind of complex transmission system, which includes power transfer, power shifting, steering and manipulation. The transmission system is the key component for realizing the overall system functions of military armored vehicle. The rationality of structure design and feasibility of assembly are the precondition for implementation of function of transmission system, which are inseparable with the step of assembly design. In order to provide a prediction for the two designs in design stage of integrated transmission system, a pragmatic system to support virtual assembly for military armored vehicle integrated transmission system is established in this paper. In the virtual assembly system, the reconstruction method of assembly features of transmission system is investigated to implement the models transform from CAD system to virtual assembly. The planning method of virtual assembly sequence is proposed, which is based on the combination of cut set method of graph theory with interactive planning in virtual environment. The sequence planning method applied the pre-identified strategy for the subassembly to improve combination explosion problem of cut set method and reduce the blindness and uncertainty caused by the direct using of interactive planning. The mixed collision checking method based on the geometrical features is presented, which can meet the real-time performance and accuracy of virtual assembly. The parts accurate positioning method based on the reconstruction of assembly features elements is proposed, which can be used for the accurate positioning in virtual environment. With these technologies and methods, the system has been successfully applied to the virtual assembly for a certain type of integrated transmission system of military armored vehicle.
