摘要:
采用新型智能材料进行结构振动主动控制是目前抗震领域的前沿方向,其中,新型抗震装置的开发,主动控制动力学模型的建立以及合理、高效的分析方法是保证主动控制技术应用到工程实际中的关键.本文根据压电堆频响范围宽、响应速度快的特点,结合机械设计二次开发,设计了压电主动杆件,阐述了主动杆件双向受力的工作原理;运用Hamilton原理,推导了压电主动杆件的有限元方程,根据主动杆件在实际应用中的装配方式,对主动杆件的自由度进行了缩减,并建立了加入主动杆件的整体结构动力学方程;基于随机振动理论,推导了结构振动主动控制方程的虚拟激励求解方法;最后对一主动控制结构模型进行了随机振动分析,高效的得到了主动控制方程随机振动解.为压电主动杆件在结构抗震中的应用提供了依据
Abstract:
Using intelligent material for structure vibration active control is the frontier in the anti-seismic field, where developing the new type seismic device, building the active control dynamics model, then through reasonable and efficient method for analysis is the key which ensures the active control technology applied in the engineering. Based on piezoelectric pile’s wide range frequency response and response speed, and through the process of mechanical design, piezoelectric driving lever is designed to, expound the working principle of two-way force driving lever. Hamilton principle is applied to, deduce the finite element equation of the driving lever. According to the driving lever assembly form, freedom degrees of the finite element model, and the active control system dynamics equation is established. Based on the pseudo-excitation method, the random vibration solution is given. Finally, through simulation of a active control model, the active control equation random vibration solution efficiency is obtained. The paper provides a basis for piezoelectric driving lever in structural seismic application
