车顶内支撑成形及回弹的模拟研究

The Numerical Simulation Study about Forming and Spring-back of the Roof Bow

介绍了数值模拟技术的应用范围及其理论基础,重点对车顶内部支撑的成形过程和回弹进行了数值模拟,并进行了验证。

This article firstly introduced numerical simulation technology and the application,and then related theoretical bedrocks on numerical simulation.After this,the article made use of DYNAFORM software to simulate the roof bow,and in the actual production carried on a verification to the spring-back of the roof bow.
