隔振隔振vibrationisolation采用适当的弹性兼阻尼装置以隔离机械振动的措施。根据激振源的不同，隔振可分为两类：①对于本身是振源的结构物，为减少其振动对周围人和物的影响，用隔振器材（如天然或人造橡胶制品、软木、毛毡制品、泡沫塑料、金属弹簧制品、不锈钢丝网制品、各种高分子化合物的粘弹性材料制品等）把振源与支承隔离开，以减小传给支承的不平衡惯性力，称为积极隔振，又称主动隔振。水泵、发动机、锻锤机械等的隔振就属此类。积极隔振系数ηz表示积极隔振效果，它等于隔振后传到支承上的力与未隔振时传到支承上的力之比。②对于振源来自支承的情况，为减少支承传给结构物的振动，把结构物安装在一个隔振台上，使它与支承隔离，这种措施称为消极隔振，又称被动隔振。精密仪器、车厢和舰艇上导弹发射架的隔振等均属此类。消极隔振系数ηb表示消极隔振效果，它等于隔振后结构物的振幅与支承运动的振幅之比。隔振系数小表示隔振效果好。两类隔振系数的计算公式相同。对于单自由度隔振系统，
