车身刚度对汽车操纵稳定性的影响研究

Research of the Influence of Body Stiffness to the Driving Dynamic

引入振动载荷传递路径上系统刚度的概念,梳理了车身刚度的分类和物理意义。明确了整体静刚度及连接点的局部静刚度、动刚度是提升系统刚度的关键。并通过介绍某车型的具体案例,研究了如何通过优化车身刚度,特别是车身局部刚度来提升汽车操纵稳定性。

The definition of system stiffness and the types of body stiffness and their physical meaning are introduced. The contributions to the driving dynamic of the global static stiffness, load path relevant local static and dynamic stiffness are studied in detail by some example.
