【摘要】 以自由速度作为描述振源激励特性的参数,通过对机器—隔振器—基座系统的分析,得到了作用于基座结构的激励力与机器自由速度之间的关系。以自由速度作为输入参数,计算加肋圆柱壳模型的受激振动响应,计算值与试验值一致,表明以自由速度表征机械设备振动特性及其作为激励力计算输入参数是合理的。最后还归纳了测量机器自由速度的安装条件。更多还原

【Abstract】 This paper uses the concept of free velocity to describe the exciting character of vibration source.By analyzing the machine-isolator-base system,the formula of the force exerted on the base is derived by using of the free velocity.Rationality of free velocity to describe the exciting character of a machine was proved by experiments.We also sum up the installation environment of measuring the free velocity.更多还原
