摘　　要：文章介绍了一种新型落球模拟冲击试验机的主要特性,该机是专门为研究结构样品的动态力学性能而设计的,这种类型的设备已被用于在中高速加载速率下产生简单且可测量的断裂过程。该机器由两个主要部分组成,即机械结构和数据采集系统,前者只是一个落球,由两个坚固的柱子引导,可以用于高能量撞击样本。后者由压电力传感器、加速度计和光纤光电传感器以及示波器和信号调节器组成。This paper introduces the main characteristics of a new type of falling ball simulation impact testing machine,which is specifically designed to study the dynamic mechanical performance of structural samples.This type of equipment has been used to generate simple and measurable fracture process at medium to high loading rates.The machine consists of two main components,namely a mechanical structure and a data acquisition system.The former is just a falling ball,guided by two sturdy pillars,and can be used for high-energy impact samples.The latter consists of piezoelectric sensors,accelerometers,fiber optic optoelectronic sensors,as well as oscilloscopes and signal conditioners.
