Research on Impact Characteristics of Needle Impact Simulation Device

为研究击针撞击模拟装置撞击过程中检测单元冲击振动特性,采用多刚体仿真软件对装置进行了刚柔耦合仿真分析,通过将模拟装置安装基座柔性化处理进行仿真,提取了模拟装置工作全过程检测装置的振动特性曲线,得出了适合检测装置检测的时间区间,为工程实践提供了理论依据。

In order to study the impact vibration characteristics of the detection unit during the impact process of the needle impact simulation device,this paper uses multi rigid body simulation software to conduct a rigid flexible coupling simulation analysis of the device.By simulating the flexible installation base of the simulation device,the vibration characteristic curve of the detection device throughout the entire working process of the simulation device was extracted,and the suitable time interval for the detection device was obtained,providing a theoretical basis for engineering practice.
