Experimental Research on Isolation Vibration Effect of Engine Suspension Based on Power Flow

Abstract

The acceleration and force sensors are taken as the measurement parameter,vibration power flow analysis is conducted to the data collected using MATLAB software,the results show that validity of engine suspension vibration is intuitively judged using the power flow,it is a evaluation index,moreover,it is not only convenient measurement,but also the influence of phase difference between the measured parameters to vibration isolation effect is not needed consider.
