When the torsional vibration amplitude and stress exceed the limit, the rubber torsional vibration damper should be designed to reduce the amplitude within the permitted range.
当扭振振幅或扭振应力超过限值时，设计橡胶扭振减振器将振幅衰减到容许范围内，消减曲轴系统的扭转振动。
Similarly, varying load conditions, as the unit load required to respond as quickly as possible, to stress the extent permitted margin shorten response time.
同样，变负荷工况下，为使机组尽快响应负荷需要，要在应力裕度允许的范围内缩短响应时间。
