Abstract: Dent resistance is an important parameter, which has influence on the using of body panel.

摘要：抗凹性是衡量车身外覆盖件使用性能的重要指标之一。

Experiments of dent resistance show that the dent resistance of isotropic steel is poorer than BH steel.

抗凹陷性测试结果表明，各向同性钢的抗凹陷性低于烘烤硬化钢。

In the end - some tests about dent resistance rigidity and depth of dent resistance have been carried out for typical steel sheet and exposed parts.

并对薄钢板和典型表面件的抗凹刚度和抗凹深度进行了检测。

The effects of baking temperature, baking time and prestrain on the bake hardenability and dent resistance of isotropic sheet steel and BH sheet steel produced by batch annealing were studied.

研究了烘烤温度、烘烤时间和预拉伸应变量对罩式炉退火工艺生产的各向同性钢的烘烤硬化性的影响，并与力学性能相当的冷轧烘烤硬化钢进行了对比。

In this paper, mechanical property, forming ability, baked-hardening and dent resistance properties of high strength steel B180H1 are studied by experiments, and compared with those of steel DC04.

本文通过试验对汽车用高强度钢板B180H1的力学性能、成形性能、烘烤硬化性能和抗凹陷性能进行了全面的研究，并与DC04钢板的各项性能进行了比较。
