摘要
本文通过有限元方法计算空气弹簧在不同温度条件下的静刚度,对比各参数变化对空气弹簧静刚度的影响,概括总结了静刚度随温度改变的变化规律。随着温度下降,空气弹簧垂向及横向静刚度均会增加。对于不同参数:只有帘线材料参数改变时,垂向静刚度和横向静刚度随温度降低而增加;只有橡胶材料参数改变时,垂向静刚度先降低后增加,横向静刚度随温度降低而增加;附加空气室容积增大会降低垂向静刚度对温度变化的敏感度;帘线角度为16°时横向静刚度最大,在64°时最小,这种趋势不受温度影响。
In this paper, the static stiffness of air spring under different temperature conditions is calculated by finite element method. Comparing the influence of various parameters on the static stiffness of air spring, the changing rule of static stiffness with temperature is summarized. With the decrease of temperature, the vertical and lateral static stiffness of air spring will increase. For different parameters : Only when the cord material parameterschange, the vertical static stiffness and the lateral static stiffness increase with the decrease of temperature;onlywhen the rubber material parameters change , the vertical static stiffness first decreases and then increases , while the lateral static stiffness increases with the decrease of temperature;the increase of the additional air chamber volume will reduce the sensitivity of the vertical static stiffness to the change of temperature;When the cord angle is 16°, the lateral static stiffness is the largest and the minimum is 64°, and this trend is not affected by temperature.
