对强迫振荡进行分析，预测根据谐波规律变化的外部动作下结构的行为。这些动作包括力和/或运动激发。此外，还可考虑系统阻尼的影响。 强制振荡分析的目的是获得系统响应对强制行动频率的依赖性。通过计算，我们可以在预设的引人注目的频率下获得位移、振动加速度和振动过载的振幅。根据这些结果，对于频率范围，可以获得振幅和振动加速度对引人注目的动作频率的依赖性，这对于评估系统在此预设频率范围内的振动稳定性非常重要。 轴或主轴在弹性支架上的不平衡状态的旋转可能起到谐波力的一个例子。当不为人所知的强制力值时，则应用运动激发，这与已知某些结构元素的振荡振幅相反。 在考虑强制振荡时，重要的是要考虑到阻尼力的影响。机械振荡的能量耗散过程，导致系统产生的一次总付振荡的一步一次衰减，即阻尼。阻尼力可能有不同的来源，即：干滑表面之间的摩擦、润滑表面之间的摩擦、内部摩擦、空气或液体阻力等。通常假定阻尼力与速度成正比（粘性阻尼）。根据自愿法变化的阻力被替换为等效阻尼力，从在一个循环中，它们消散的能量与实际力相同的情况开始。
