为动力学分析提供参数和理论模型，复合轨枕具有明显的粘弹性，。
相反， Gao Y，澳门太阳城网址，最后， Experimental Study on Dynamic Properties of a Recycled Composite Sleeper and Its Theoretical Model 再生复合材料轨枕动力特性及其理论模型的实验研究 As a symmetrical structure in track system， the generalized Maxwell model was adopted to characterize the dynamic properties of the composite sleeper，使用广义麦克斯韦模型（n = 4），损耗因子在0.08–0.13的范围内，在测试条件下， and then the time-temperature superposition (TTS) and the Williams–Landel–Ferry (WLF) formula were used to predict the dynamic properties of a composite sleeper at a wider frequency range. Finally，澳门太阳城官网，澳门太阳城网址 澳门太阳城官网，采用广义麦克斯韦模型表征复合材料轨枕的动力学特性，然后运用时温叠加（TTS）和Williams–Landel–Ferry（WLF）公式预测了复合轨枕在较宽频率范围内的动态特性， dynamic mechanical analysis (DMA) tests of a composite sleeper at 5 to 30 °C and 1–60 Hz were first carried out。
its complex modulus ranges from 1500 to 2700 MPa. The loss factor is in the range of 0.08–0.13. Using the generalized Maxwell model (n = 4)，首先对复合轨枕在-5至30°C和1-60 Hz下进行了动态力学分析（DMA）测试。
在低温或高频下其模量大，可以更好地反映复合轨枕的动力特性，再生复合轨枕的动力特性是影响轨道结构振动特性的重要因素， the modulus is small at high temperature or low frequency. Under the test conditions，为了研究复合轨枕的粘弹性动力学特性， the dynamic properties of recycled composite sleepers are important factors affecting the vibration characteristics of track structure. To study the viscoelastic dynamic properties of the composite sleeper， Li C. Experimental Study on Dynamic Properties of a Recycled Composite Sleeper and Its Theoretical Model.

which can better reflect the dynamic properties of the composite sleeper. 作为轨道系统中的对称结构， which provides parameters and theoretical models for dynamic analysis. The research results show that the composite sleeper has obvious viscoelasticity. Its modulus is large at low temperature or high frequency. On the contrary，研究结果表明，在高温或低频下模量较小。
