摘　　要：研究合成杜仲橡胶(TPI)在汽车扭力梁铰接中的应用。结果表明,在天然橡胶体系中并用少量TPI,可以在保持原胶料物理性能基本不变的情况下,大幅提高伸张疲劳性能、耐屈挠疲劳性能和动态力学性能;将TPI用于汽车扭力梁铰接能够显著改善耐动态疲劳性能。The application of trans-1,4-polyisoprene（TPI） in the hinge of automobile torsion beam was studied. The results showed that with a small amount of TPI in natural rubber（NR） system,the tensile fatigue property,flex fatigue resistance and dynamic mechanical property were highly improved while the other physical properties were basically unchanged. The fatigue performance of the hinge was significantly improved when TPI was applied.
