高速列车头型的意象仿生设计

Image bionic design of high speed train head modeling

为提升我国高速列车的品牌形象,增强其文化适应性和地域感召力,提出了高速列车意象仿生设计方法。利用思维流程分析法细化了设计步骤,讨论了意象确定过程中本身意象和对象意象两者的匹配,并确定了方案设计过程中意象表现和技术约束间的取舍,指出列车意象仿生有隐喻产品性能、契合用户身份、提升品牌形象3个目的。设计了大白鲨意象的列车造型,并对方案的气动性能进行验证。实例表明:意象仿生时,本身意象和对象意象的匹配可由设计目的确定,但意象和技术间的取舍需要根据具体情况确定。该方法有助于设计人员更精准地把握意象—仿生设计的过程,促进轨道车辆造型设计发展。

In order to improve the brand image of CRH（China Railway High-speed） and enhance the cultural adaptability and regional charisma, an image bionic design method of CRH train was presented. The design procedure was refined using thinking process analysis method. The matching between own image and object image during the image determination process were discussed. The choice of acceptance and rejection of image expression and technology constraint was determined. There were 3 purposes in train image bionic, which were metahporing product performance, fitting users ID and promoting the brand image. A train modeling case with shark image was designed, and the aerodynamic performance in the scheme was verified. The instance revealed that the matching between own image and object image could be determined by design objective. However,the choice of acceptance and rejection between image and technology need to be determined according to the particular case.This method help the designers seize the design process of image bionic more accurately, which could promote the development of rail vehicle modeling design.
