中文摘要:
      目的 研究橡胶辊在交变载荷作用下因滞后作用造成的温升。方法 采用有限元数值计算方法,得到橡胶辊在交变载荷作用下的应力应变历程,并据此编程计算滞后生热率,以此作为材料单元的内热源进行热传导有限元计算,得到其温度场分布。同时研究不同载荷、损耗因子、转速及材料厚度这4种因素对橡胶辊滞后温升的影响。结果 橡胶辊平均滞后温升和最高滞后温升都随载荷、损耗因子、转速的增加而增加,随厚度的增加而减小,其中载荷因素对滞后温升影响最大,最高滞后温升约为2~10 ℃。结论 合理设计及选择橡胶辊材料、尺寸、载荷及转速,可有效避免生热以及因热造成的疲劳损坏,延长橡胶辊的使用寿命。
英文摘要:
      The paper aims to study the temperature rise of the rubber roller under the action of alternating load. The stress and strain course of the rubber roller under the alternating load was numerically simulated with the finite element method. The heat generation rate was calculated by programming under the stress and strain. The temperature field distribution was obtained by to calculate the finite element of heat conduction for internal heat source of material unit. Meanwhile, influences of different load, loss factor, speed and material thickness on temperature rise of rubber roller were researched. Average and maximum hysteresis temperature rise of rubber roller increased with the increase of load, loss factor, speed, and decreased with the increase of thickness, in which the load had the maximum impact on hysteresis temperature rise, which was about 2~10 ℃ to the maximum. Proper design and selection of material, size, load and speed for rubber roller can effectively avoid overheating and heat damage and extend the service life of rubber roller.
