【摘要】 通过分析机械系统多体动力学解算模型特点,从机械产品的协作开发与仿真角度,研究了基于组件方法建立机械系统虚拟原型,提出利用MVC设计模式构建多体动力学解算仿真模型。这种解算模式,实现了多体动力学解算仿真中,模型与解算逻辑的分离,维护了系统仿真中构件、铰约束、力元等组件的状态一致性。利于在不同的解算逻辑下组件和仿真方案的配置,方便了基于组件的协同开发与仿真。结果表明,基于组件的机械虚拟原型模型与多体动力学MVC仿真模型是可行的。更多还原

【Abstract】 The solving model characteristic of mechanical multibody dynamics is analyzed in the paper,and the building of mechanical virtual prototype based on component is studied,At the same time,the building of solving simulation model of multibody dynamics in MVC design pattern is presented.Separating the solving logic from multibody dynamics model achieves the consistency of status of constraint and force element component in multibody dynamics system simulation.Configurations of component and simulation scheme in varies solving logics are optimized,thus making concurrent development and simulation convenient based on component.The result indicates that building mechanical virtual prototype in MVC simulation model of multibody dynamics based on component is feasible.更多还原
