基于数值模拟技术的产品概念设计方法
|
摘要
为解决传统工业设计流程中,设计方案缺乏相应工程技术的校验,导致设计返工率高及开发效率低下的问题,借助于数值模拟技术可实现产品性能预评估的优势,提出一种基于数值测试技术为驱动的产品概念设计方法。首先对产品的工作机理进行数值分析,明确合理的设计方向,并以此为基础指导产品造型设计,然后再次运用数值测试分析手段对设计方案的可行性进行验证,最后对通过验证的方案进行细节完善并输出最终设计概念。数值模拟技术与产品概念设计过程相融合,驱动设计过程的逐步完善,可实现提升设计效率与质量的目的,通过电热毛巾架的设计实例验证了方法的有效性。
In order to solve the lack of engineering verification in the traditional industrial design process, which leads to the problems of high design rework rate and low development efficiency, this paper proposes a product conceptual design method based on numerical simulation technology which has the advantage of pre-assessment of product performance. Firstly, numerical investigation of the working mechanism of the product is carried out for defining the rational design direction to guide the product appearance design. Then the feasibility of the design solution is verified by using the numerical test analysis method again. Finally, the details of the verified design solution are refined so that the final design concept is output. The combination of numerical simulation technology and product concept design process can drive the gradual improvement of the design process, which can be used to improve design efficiency and design quality. The proposed method is verified by an industrial design of towel warmer.
