摘要：

压接作为金属类工件的一种连接方式，其压接质量的好坏会直接影响该类型工件的使用。该文总结现有检测方法的不足，以钢制棒材与铝制套管的被压接工件作为研究对象，分析被压接工件的结构及典型的压接缺陷，提出基于超声波的压接质量检测方法。仿真分析超声波的声场分布，得到适用于压接质量检测的探头频率。搭建压接质量超声检测试验系统，并对试块和被压接工件进行检测。结果表明：超声检测技术能够实现对被压接工件压接质量的检测，径向和轴向检测准确度达0.1 mm，可满足检测要求，验证该文提出方法的可行性和有效性。

Abstract: As a connection way of metal workpiece, the quality of crimping will directly affect the use of this type of workpiece. This paper summarizes the shortcomings of the existing detection methods, and takes the crimped workpiece of steel bar and aluminum sleeve as the research object, analyzes the structure and typical crimping defects of the crimped workpiece, and puts forward the detection method of crimping quality based on ultrasonic. The ultrasonic field distribution is analyzed by simulation, and the probe frequency suitable for crimping quality detection is obtained. Set up ultrasonic testing system of crimping quality, and test the test block and crimped workpiece. The results show that the ultrasonic detection technology can achieve the detection of the crimping quality of the crimped workpiece, the radial and axial detection accuracy is up to 0.1 mm, which can meet the detection requirements, and verify the feasibility and effectiveness of the proposed method.
Keywords: crimped workpiece;crimping quality;ultrasonic testing;simulation analysis
