| It is a valuable research issue to investigate the dynamic characteristics of flexible coupled isolation system from the viewpoint of power. This dissertation is supported by the project of National Natural Science Foundation Of China (NSFC) "Study On Intelligent System of Vibration Control of Complex Large Beam-like Structures In Engineering "(5027 5085) and "Optimum Control of Complicated Mechanical Systems Dynamic of Flexible Foundation "(59575023). In this paper,the power flow transmitting characteristics in inclined isolation system is studied in detail.The main research are as follows:The method of study vibration transmission is summarized, the power flow theory is stated, the general ideas of vibration isolation design are introduced.Aimed at practical isolation designs in engineering, an inclined isolator system with multiple mountings on a flexible foundation is modeled? in which the dynamic interactions between machine and floor, and among different mounting points are taken into account. The expression of power flow transmission is presented and the power flow transmission characteristics is analyzed in this paper. The power flow spectra is given and it's curves are plotted.System simulation is stated and road surface model is established. With the use of the software SIMULINK,2 Degrees of Freedom of suspensions model is given and simulated.From the simulation ,the vehicle body acceleration curve is plotted.At last, the test investigation on the characteristics of power transmission is performed. The results show that the models and theories in this dissertation are available and reliable. And some measures are put forward to improve the precision of the result. |
