摘　　要：为满足多场景下微振动测试及实验教学需求,设计了基于NI-cDAQ和LabVIEW的多场景微振动实验平台,并将其应用于教学实践中。该实验平台精确度高、开放性强,可用于测量表面波速、桩基施工、高铁轨道、地铁车站、桥梁结构等多种复杂场景下的微振动,能有效测得x/y/z三向振动加速度时程、频谱等参数,为研究交通引起的微振动提供可靠数据。该平台的使用,显著提高了学生对微振动诱发、传播和控制等原理以及测量方法的理解程度,夯实了基础理论知识,锻炼了创新思维。In order to meet the requirements of multi-scene micro-vibration testing and experimental teaching, a multi-scene traffic micro-vibration experimental platform based on NI-c DAQ and LabVIEW was designed and applied in teaching practice. The experimental platform has high accuracy and strong openness, which can be used to measure micro-vibration of surface wave velocity, pile foundation construction, high-speed railway track,subway station, bridge structure and other complex scenes. It can effectively measure the acceleration time history and spectrum of x/y/z three-way vibrations, providing reliable data for the study of micro-vibration caused by traffic. The use of this platform significantly improves students’ understanding of micro-vibration induction,propagation and control principles and measurement methods, strengthens students’ basic theoretical knowledge and exercises their innovative thinking ability.
