摘要
针对结构振动理论课程内容的复杂性、抽象性和枯燥性等特点,利用机械设计、振动力学及计算机等技术开发了一种用于模拟结构振动的电动伺服教学实验平台,平台主要由振动平台机架、伺服控制单元、动作执行单元、振动平台、激振系统、高清图像快速采集系统、数据采集处理及模态分析系统组成。可对不同类型结构的振型进行教学演示,测试结构的动力特性、地震波响应及进行模态分析。平台可直观捕捉到结构振动的全过程,有助于学生加强对振动形态的感官认识,加深对结构振动理论知识的理解。
In view of the complexity, abstractness and dullness of the structure vibration theory course, an electric servo teaching experiment platform for simulating structural vibration is developed by using technologies such as the mechanical design, vibration mechanics, computer, etc. The platform is mainly composed of the vibration platform frame, servo control unit, action execution unit, vibration platform, excitation system, high-definition image rapid acquisition system, data acquisition and processing and modal analysis system. It can demonstrate the vibration modes of different types of structures and test the dynamic characteristics, seismic response and modal analysis of structures. The platform can directly capture the whole process of structural vibration, which is helpful to enhance students’ sensory understanding of vibration morphology and deepen their understanding of structural vibration theory.
