摘要
随着顾客对NVH要求的提高,整车上各个模块已将NVH的参照指标作为一个关键性指标进行设计,而刚度的分析是进行产品设计过程中的一个重要参考点。文章论述了刚度指标中的动、静刚度的相关性,并以公司自产的载货汽车的变速箱吊挂的开发过程为例,示范了刚度指标在设计开发过程中运用,以实车的验收结果证明了这一设计方向的可行性。
With the increase of the customers requirement to NVH, each module on the vehicle has the harshness NVH reference index as a key index to carry on the design. Stiffness analysis is an important reference point in the process of product design. This paper discusses the stiffness index of the correlation of Dynamic Stiff and Static Stiff. An example is a projectof the production of truck transmission hanging development process. It demonstrates the rigidity indicators used in design and development process. The vehicle experiment results prove the feasibility of the design direction.
