摘要
提出了一种可用于设备的聚氨酯复合隔振垫,它由聚氨酯和热塑性聚氨酯弹性体(TPU)材料通过二次注塑而成,然后以压缩机的隔振为例,对隔振系统中的该隔振垫进行设计,并采用公司的仿真软件对其进行动态应力分析来指导设计,最后进行台架耐久对比试验.试验结果初步证明,该材料的隔振垫比橡胶隔振垫具有更好的耐久性能和更轻的质量.
Abstract
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.
