摘要
研究了装配形式与动力学约束的关系,提出了一种基于装配模型的虚拟样机建模方法。通过装配形式与动力学约束的一一映射,将各个约束模型搭建成整体虚拟样机模型。分析了基于装配的虚拟样机建模原理,研究了Pro/E中几种装配约束与动力学约束模块的对应关系,以及齿轮传动模型的建模方法。利用Simulink下面向机构分析的Sim Mechanics对一个自建的简单机构进行了概念验证。验证结果表明基于装配模型的虚拟样机建模的方法可行,此方法为研究装配对样机性能的影响奠定了技术基础。
A new method of virtual prototyping modeling was proposed based on assembly model, concerning the relation between assembly forms and dynamic constrains. With the transformation of assembly forms and dynamic constrains, a virtual prototyping model was built by the use of constrain models. Analysis of principle of modeling virtual prototype based on assembly was carried out, and the corresponding relationship between the assembly constraints in Pro/E and constraint block was studied and the method of modeling gear transmission was researched. With the utility of Sim Mechanics, a model library facing mechanism analysis under Simulink, a concept verification of a simple self-built machine was executed. The result shows that the method of virtual prototyping modeling based on assembly model is feasible, and this method provides technological base for researching the prototype performance influenced by assembly.
