| 摘 要： | 分析了我国典型的４种轮对导纳特性,结果表明：轮对辐板横向导纳较大,减小高频振动应以减小辐板横向导纳为主。轮对减振可以通过整轮对刚度的分配,充分利用导纳的相位,改变轮轨接触特性等实现。

| Abstract: | The admittance characteristics of four kinds of Chinese wheelsets under high frequency excitation are analyzed. Results show that the highest admittance is in the axial ( i.e. , lateral) direction of wheelset spoke, and the main way to reduce the high frequency vibrations is to reduce the wheelset spoke lateral admittance. Reducing wheel vibrations can be accomplished by adjusting the wheelset stiffness distribution, making full use of the admittance phase, and modifying the wheel rail contact characteristics. |
