摘　　要：为了研究高弹联轴器在压裂车作业过程中对车台上柴油发动机型号是否匹配、以避免两者发生共振,本文在指定柴油发动机的情况下对高弹联轴器的选型及匹配进行研究分析。首先对高弹联轴器进行理论选型计算,然后对选出来的高弹联轴器建立三维模型,并导入ANSYS中对其进行静力学分析模态分析,得到其前10阶固有频率与主振型。然后在模态分析基础上,再对其进行谐响应分析,得到其加速度、位移变形及应力响应曲线,根据其谐响应曲线结果分析可知,该高弹联轴器对应的危险激振频率段为0~110 Hz、危险频率点为21 Hz和39 Hz。通过对高弹联轴器的静态及动态分析,使得所选择的高弹联轴器变得更加可靠和安全,也为今后对用于压裂车的高弹联轴器提供了结构设计思路和优化理论依据。In order to study whether the high-elastic coupling matches the diesel engine model on the platform during the fracturing vehicle operation and to avoid resonance between the two,this article selects and matches the high-elastic coupling under the condition of specified diesel engine.First,the theoretical selection calculation of the high-elastic coupling is carried out,and then a three-dimensional model is established on the selected high-elastic coupling.ANSYS is applied for static analysis and modal analysis,and the first 10 natural frequencies and the main frequency modes are obtained.Based on the modal analysis,the harmonic response analysis is carried out to obtain the acceleration,displacement,deformation and stress response curves.The results show that the dangerous excitation frequency corresponding to the high elastic coupling is 0~110 Hz and dangerous frequency points are 21 Hz and 39 Hz.Through the static and dynamic analysis,more reliable and safe high-elastic coupling is selected.This study provides structural design ideas and optimization theory basis for the high-elastic coupling used in fracturing vehicles in the future.
