摘要
为了加快产品设计进程朝设计目标收敛,提出了产品设计进程反馈模型,包括产品描述语义模型、分析视图语义模型和性能仿真语义模型,并将其融合在设计中.整个反馈模型是基于建立在CAD环境下的数字化样机模型,因此保证了产品设计目标的整体性和设计进程的一致性.以多体系统意义下机车车辆虚拟样机为例,给出了产品描述语义模型、分析视图语义模型和性能仿真语义模型的具体形式,以验证该反馈模型的正确性.
In order to accelerate the convergence of a product design process towards the design object, a feedback model for product design processes was proposed. This model includes a product design model, an analysis model and a simulation model, and they are syncretized in a product design process. The proposed model is based on a digital prototype built in the CAD environment, so it can guarantee the entirety of the design object and the consistency of the design process. By taking the virtual prototyping of a locomotive based on the multi-body system as an example, the concrete forms of the product design model, the analysis model and the simulation model were given to testify the validity of the proposed model.
