Design and applications of polyurethane composite isolator in power equipment
A composite isolator was proposed for the used in power equipment and then formed through over-injection molding using polyurethane and thermoplastic polyurethane elastomers as raw materials.Taking the isolation of a com-pressor as an example,the composite isolator was designed,and the dynamic stress analysis of the designed composite isolator was simulated by using the simulation software of the company to provide a guide for the design.Finally,the re-sults from the durability-comparative experiment of the composite isolator and rubber isolator preliminarily indicated that the composite isolator exhibited better durable performance and lighter weight than the rubber isolator.
