注塑新产品开发中的设计验证

为减少新产品开发中的设计错误，针对技术不确定性假设，综合运用样品技术、实践经验、试验方法、CAD技术、CAE技术，提出了6种设计验证方法.这些方法包括：基于粗略/精确样品的设计验证、基于经验的设计验证、基于实验的设计验证、基于CAD的设计验证、基于加工仿真的设计验证以及基于集成仿真的设计验证.通过注塑制品开发实例，表明这些设计验证方法可应用于新产品开发的概念提出、设计工程、原型测试及试生产阶段.

Design validation during new injection-molded product development

The technical design assumptions during new product development were discussed in order to reduce design errors. Combined with prototype technology， experiences， experiments， CAD and CAE technologies， six design validation methods were put forward. They are prototype validation， experience validation， experiment validation， CAD validation， processing simulation validation and integrated simulation validation. These methods were applied in the new product developments of injection molded parts. It shows that these six design validation methods can be applied in concepts， design， prototype testing and the trial production stages of new product development．
