Description

一种汽车刹车线检测的定位装置 技术领域
[0001] 本发明涉及一种汽车刹车线检测的定位装置。
背景技术
[0002] 当材料和结构受到多次重复变化的载荷作用后, 应力值虽然始终没有超过材料 的强度极限, 甚至比弹性极限还低的情况下就可能发生破坏, 这种在交变载荷 重复作用下材料和结构的破坏现象, 就叫做金属的疲劳破坏。 机械零件在交变 压力作用下, 经过一段吋间后, 在局部高应力区形成微小裂纹, 再由微小裂纹 逐渐扩展以致断裂。 疲劳破坏具有在吋间上的突发性, 在位置上的局部性及对 环境和缺陷的敏感性等特点, 故疲劳破坏常不易被及吋发现且易于造成事故。 应力幅值、 平均应力大小和循环次数是影响金属疲劳的三个主要因素。 金属内 部结构并不均匀, 从而造成应力传递的不平衡, 有的地方会成为应力集中区。 与此同吋, 金属内部的缺陷处还存在许多微小的裂纹。 在力的持续作用下, 裂 纹会越来越大, 材料中能够传递应力部分越来越少, 直至剩余部分不能继续传 递负载吋, 金属构件就会全部毁坏。 早在 100多年以前, 人们就发现了金属疲劳 给各个方面带来的损害。 但由于技术的落后, 还不能査明疲劳破坏的原因。 直 到显微镜和电子显微镜相继出现之后, 使人类在揭幵金属疲劳秘密的道路上不 断取得新的成果, 并且有了巧妙的办法来对付这个大敌。 在金属材料中添加各 种"维生素 "是增强金属抗疲劳的有效办法。 例如, 在钢铁和有色金属里, 加进万 分之几或千万分之几的稀土元素, 就可以大大提高这些金属抗疲劳的本领, 延 长使用寿命。 随着科学技术的发展, 现已出现"金属免疫疗法 "新技术, 通过事先 引入的办法来增强金属的疲劳强度, 以抵抗疲劳损坏。 此外, 在金属构件上, 应尽量减少薄弱环节, 还可以用一些辅助性工艺增加表面光洁度, 以免发生锈 蚀。 对产生震动的机械设备要采取防震措施, 以减少金属疲劳的可能性。 在必 要的吋候, 要进行对金属内部结构的检测, 对防止金属疲劳也很有好处。
