摘要: 白车身焊点质量检测应用最为广泛的是超声波检测,传统超声波焊点检测效率较低,同时所检焊点选取仅凭路试和经验确定,耗时较长,并且缺乏相应的理论选定方法。针对某一车型,提出选取关键焊点区域的方法,对传统检测方法进行优化,并且阐述了焊点关键区域选取的具体思路。通过CAE工具,对车身性能进行了强度、碰撞性能分析,选取车身高应力和碰撞过程中高吸能区域进行焊点检测,满足了车身关键性能同时减少了待检焊点个数。Abstract: Ultrasonic inspection is widely used in quality detection of solder joint of white body. There is the lowefficiency of traditional ultrasonic inspection for solder joint. The solder joints are selected only according to theroad test and experience, which takes long time and is lack of the theory of selection method. Focusing in car, themethod of selecting key spot area is proposed, meanwhile the traditional detection method is optimized, and theidear for selecting the key areas in solder joint is stated. By using CAE tool, the strength and impacted performancefor the vehicle performance is analyzed, the solder joints located in the areas that with the high stress and highenergy absorption in collision processes are detected, the results show that the method reduces the number of solderjoints to be detected and meets the main performance of body.
