为了提高超高分子量聚乙烯（UHMWPE）中空制件的机械性能和耐磨性能，采用自主研制的中空制件成型模具，在模压成型过程中引入脉冲振动，使物料在脉冲压力下实现成型，研究脉冲振动对制件微观结构及宏观性能的影响。通过拉伸测试、砂浆磨耗测试、DSC测试、密度测试和2D-WAXD测试，结果表明：施加脉冲振动可提高样品的致密化程度、取向度和结晶度，其拉伸性能和耐磨性能均优于静态条件下成型的制件。

In order to improve the mechanical properties and wear resistance of ultra-high molecular weight polyethylene (UHMWPE) hollow parts, a self-developed hollow part forming mold was used, and pulse vibration was introduced during the compression molding process, so that the material can be formed under pulse pressure. The effect of impulsive vibration on the microstructure and macroscopic properties of the part was studied. Through tensile test, mortar abrasion test, DSC test, density test and 2D-WAXD test, the results show that the application of pulse vibration can increase the density, orientation and crystallinity of the sample, and its tensile properties and wear resistance are better than those molded under static conditions.
