浅析尺寸工程在汽车产品开发中的应用

Analysis of Application of Dimension Engineering in Automotive Development

为提高整车缝隙的外观感知质量,阐述了汽车在产品开发全生命周期的尺寸工程工作内容及应用,进而引入用户视角,构建兼顾客观数值和主观用户感知的整车静态外观尺寸技术规范(DTS)设定思路;应用虚拟评审技术,保证DTS设定的合理性;建立精致工程及看穿性评价标准,实现兼顾造型意图和工艺能力的实车效果,旨在平衡成本和质量,从而实现质量目标。

To address the issue of perceived quality in the appearance of vehicle gaps,this article mainly described the content and application of dimensional engineering in the entire product development life cycle of automobiles.The user’s perspective was introduced and a Dimensional Technical Specifications(DTS)setting approach balancing objective numerical values and subjective user perception was constructed.Virtual evaluation technology was applied to ensure the rationality of DTS settings.A refined engineering and visual evaluation standards was established to achieve a practical vehicle effect that balanced design intent and craftsmanship,aiming to find a suitable balance between cost and quality,and thus achieving quality objectives.
