以舰舶柴油机双层隔振装置为对象，研究了隔振装置中的振动功率流，用不同的振动功率流测量方法测量了通过隔振器传到上、下层质量和流入弹性基础中的振动功率流．不同的测量方法得到了类似的测量结果．可以利用隔振器上、下端的加速度互谱密度和隔振器的传递视在质量测量通过每个隔振器传递的振动功率流；也可以通过各接触点的有效导纳和加速度测量通过各接触点传递的振动功率流．
Taking the dual-layer vibration isolation device of a marine diesel engine as an example, the vibration power flow in the vibration isolation device is studied. The vibration transmitted to the upper and lower layers through the vibration isolator and the inflow elastic foundation is measured by different vibration power flow measurement methods Power flow. Different measurements give similar measurements. The vibration power flow passing through each vibration isolator can be measured by using the acceleration cross-spectral density of the upper and lower ends of the isolator and the apparent mass transfer of the isolator. The effective admittance and acceleration of each contact can be measured by Vibration power flow delivered by the contact point.
