%X 采用试验的方法分析了密度、金属丝直径、螺旋卷直径及温度对环形金属橡胶径向刚度的影响，以悬臂曲梁为基本单元，分析了金属橡胶的受力变形情况，结合温度对金属丝弹性模量及接触曲梁的影响，建立了包含主要制备参数及温度影响的金属橡胶径向力学模型。同时，依据试验结果，对力学模型的参数进行拟合求解，确定了模型的具体表达式。通过将模型计算结果与试验结果对比后发现，力学模型有较高的精度，可以比较全面地反映环形金属橡胶的径向刚度特性，为金属橡胶的实际应用提供了理论参考。<br>The effects of the density, diameter of wire, diameter of spiral coil and temperature on the radial stiffness of ring metal rubber are analyzed via experiment. Taking the cantilever beams as the basic unit, the deformation of mental rubbers is analyzed. Combing with the temperature effect on the elastic modulus of wire and contact beams, the radial mechanical model for metal rubbers containing main parameters and temperature is established. Meanwhile, according to the experimental results, the parameters in the mechanical model are fitted and the concrete expression of the model is obtained. Comparing the model results with the experimental, it is found that the accuracy of the mechanical model is high and the model can comprehensively describe the radial stiffness of ring metal rubbers. It provides a theoretical reference for the practical application of metal rubbers
