Abstract  In order to reduce the harmful vibration of power equipment and building floor, the passive and active dynamic vibration absorption (DVA) was systematically studied. Particle swarm optimization (PSO) algorithm was introduced to optimize the design of the parameters of passive DVA without damping and with damping in the main system, the weight matrices in linear quadratic regulator (LQR) active control and the parameters of kp, ki, kd in proportion-integral-derivative (PID) active control. In the vibration control of building floor, based on the utilization of passive tuned mass damper (PTMD), an active tuned mass damper (ATMD) was designed for vibration control in ANSYS finite element environment. The results verified the feasibility and effectiveness of the proposed strategy, and provide a basis for the calculation and effect prediction for engineering structure vibration control. The research can further develop the advanced DVA technology for power equipment and building floor.

动力装备和建筑楼盖的动力吸振研究

为减弱动力装备和建筑楼盖的有害振动,对其被动、主动型动力吸振进行系统研究。引入粒子群优化(particle swarm optimization, PSO)算法,对主系统无阻尼和有阻尼被动型动力吸振的参数、采用线性二次型调节器(linear quadratic regulator, LQR)主动控制中的权矩阵、PID(proportional-integral-derivative, 比例-积分-微分)主动控制中的参数kpkikd进行优化设计;在建筑楼盖的振动控制中,基于引入的被动调谐质量阻尼器(passive tuned mass damper,PTMD),在ANSYS有限元环境中,设计了一种采用主动调谐质量阻尼器(active tuned mass damper, ATMD)进行振动控制的方法,结果验证了所提策略的可行性和有效性,为工程结构振动控制的计算和效果预判提供了依据。研究进一步发展了动力装备和建筑楼盖的先进动力吸振技术。
