聚氨酯复合隔振垫在设备中的设计及应用

Design and applications of polyurethane composite isolator in power equipment

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。

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.
