Abstract
Abstract This article proposes a rigid body modular modeling method based on bond space theory. Aiming at the rigid components with the same characteristics that are heavily used in artillery weapon systems, the concept of bond space sub-model is proposed, and the rigid body module and constraint module are established and deduced. Considering the differences between ideal constraints and actual constraints such as gaps or heat losses, an elastic constraint bonding space module is proposed to improve the representation of ideal constraints. By combining bond space modules with the same characteristics and solving them, the process of analyzing complex systems will be greatly simplified. In addition, a study case of ammunition box feeding is presented to investigate the computational results of this modeling method; the analysis results show that this modeling method has good computational accuracy on the basis of improved computational efficiency.
