摘要: 抗凹性是评价汽车板使用性能的一项重要指标.建立了汽车板抗凹性评价体系,并从试验原理 、试件制备以及评估参数等方面作了系统的描述.在此基础上,开发了基于微机控制的专用 抗凹性试验机系统,详细介绍了试验机构成、测控系统以及加载系统.应用表明试验结果 稳定可靠.

Abstract: The sinking-resistance is one of the important performance properties of automo bile panel. The evaluation methods of sinking-resistance for auto-body sheet w ere proposed and some key factors were introduced, which include test principle, shapes/status of specimens as well as evaluating parameters of test r esults.The special test machine for evaluating sinking-resistanc e was developed, which is controlled by micro-computer. Its struc ture, measurement and control system as well as loading system were described. The application in the factory indicates that the test results are stable and relia ble.
