摘要

在概念设计阶段,简化框架被广泛应用于白车身结构,以快速计算其性能。然而,为了计算车身结构的弯曲刚度、扭转刚度和频率,很难获得精确的简化框架。因此,本文提出了一种采用复杂截面薄壁梁、半刚性单元和横梁结构的简化建模方法。与传统的建模方法相比,twb包含了更多的复杂截面类型,采用半刚性单元描述各种变形,采用横梁结构代替板结构,提高了简化框架的精度。工程实例表明,简化后的框架可以加快白车身结构的概念设计。

Refined modelling of thin-walled beam, plate and joint for automobile frame
At the conceptual design stage, the simplified frame is extensively applied in the body-in-white (BIW) structure to rapidly calculate its performances. However, it is difficult to acquire an accurate simplified frame of the BIW structure for the calculation of the bending stiffness, torsional stiffness and frequencies. Therefore, this paper proposes a simplified modeling method by using the thin-walled beams (TWBs) with complex sections, semi-rigid elements and cross beam structures. Compared with the traditional modelling method, the TWBs contain more types of the complex sections, the semi-rigid elements are used to describe various deformations, and the plate structure is replaced by using the cross beam structure to improve the accuracy of the simplified frame. An engineering example demonstrates that the simplified frame can accelerate the conceptual design of the BIW structure.
