【摘要】 基于灵敏度分析与结构动力学修改的控制策略,以获得结构受控振型最大阻尼比为目标,给出了变阻尼滑模控制器在结构振动控制中的位置优化算法。算例分析表明,优化后的变阻尼结构的滑移模态控制效果接近主动控制效果,但所需能源显著下降,大大提高了其适用性。更多还原

【Abstract】 Based on the sensitivity analysis and modified controlling strategy of structural dynamics,the paper takes the obtain of the maximal damping ratio of the structural controlled vibration type as the aim,provides the position optimization calculation method of the variable damping sliding mode controller in the structural vibration control,proves that the controlling effect of the optimized variable damping structure is close to the active control effect,but the needed energy declined obviously,so this improves its applicability.更多还原
