Analysis of material parameter effects on fluidlastic isolators performance
Control of vibration in helicopters has always been a complex and challenging task.The fluidlastic isolators become more and more widely used because the fluids are non-toxic,non-corrosive,nonflammable,and compatible with most elastomers and adhesives.In the field of the fluidlastic isolators design,the selection of design parameters of fluid and rubber is very important to obtain efficient vibration-suppressed.Aiming at getting the property of fluidlastic isolator to material design parameters,a dynamic equation is set up based on the dynamic theory.And the dynamic analysis is carried out.The influences of design parameters on the property of fluidlastic isolator are calculated.The material parameters examined are the properties of fluid and rubber.Analysis results showed that the design parameters such as density of fluid,viscosity coefficient of fluid,stiffness of rubber(K1)and loss coefficient of rubber have obvious influence on the performance of isolator.Base on the results of the study it is concluded that the efficient vibration-suppressed can be obtained by the selection of design parameters.
