Research on Accelerated Life of Polyurethane Vibration Isolator
In this paper,polyurethane vibration isolator is taken as the research object,and accelerated life test is carried out.Polyurethane material samples are selected for thermogravimetric test to obtain activation energy values of different vibration isolator materials.Degradation data of samples are obtained through high temperature aging test and static and dynamic stiffness test,and the test data are analyzed and calculated.The estimated equivalent life of polyurethane vibration isolators at actual operating temperature provides support for life prediction of similar products.
