摘　　要：为了探究橡胶弹簧的结构参数、材料参数和预压量等因素对扭转刚度灵敏性影响,笔者提出一种橡胶弹簧扭转刚度灵敏性研究方法。笔者基于橡胶超弹性及黏弹性理论,构建了橡胶弹簧超弹性-黏弹性本构模型,并在ABAQUS中建立了橡胶弹簧动态分析有限元模型,通过橡胶弹簧动态扭转试验验证了其有限元模型的正确性;基于橡胶弹簧动态分析有限元模型,讨论了橡胶的高度、直径、预压量、硬度、激励频率和扭转角度对橡胶弹簧扭转刚度的灵敏性,获得了各因素对扭转刚度的影响规律;基于灵敏性分析结果,建立了振动输送机能耗优化数学模型,应用遗传算法对振动输送机能耗进行优化。结果显示优化之后振动输送机能耗降低了10.25%。橡胶弹簧扭转刚度灵敏性分析方法对振动输送机橡胶弹簧的开发设计提供了一种设计周期短、计算效率高的方法。In order to explore the effects of structural parameters, material parameters, preload and other factors of rubber spring on the sensitivity of torsional stiffness, a method for studying the sensitivity of torsional stiffness of rubber spring was proposed.The superelastic-viscoelastic constitutive model of rubber spring was constructed based on the theory of superelasticity and viscoelasticity of rubber, and the finite element model of dynamic analysis of rubber spring was established in ABAQUS. The correctness of the finite element model was verified by the dynamic torsion test of rubber spring. The sensitivity of rubber height, diameter, preloading, hardness, exciting frequency and rotation angle to the torsional stiffness of rubber spring were discussed based on the finite element model of dynamic analysis of rubber spring, and the influence rules of various factors on the torsional stiffness were obtained. Based on the results of sensitivity analysis, the mathematical model of energy consumption optimization of vibration conveyor was established, and the genetic algorithm was used to optimize the energy consumption of vibration conveyor. The results show that the energy consumption of vibration conveyor is reduced by 10.25% after optimization. The sensitivity analysis method of torsional stiffness of rubber spring provides a shorter design period and higher calculation efficiency for the development and design of rubber spring of vibration conveyor.
