中文摘要:
      利用Abaqus软件对225/40R18轮胎阶梯式直压硫化内模具（简称内模具）的结构强度进行研究。结果表明：内模具在4.6 MPa的硫化压力下，最大应力出现在宽鼓瓦楔块滑块上，远小于滑块材料铍青铜的许用应力；内模具机构的最大变形位移为0.140 7 mm，其变形为弹性变形，对机构运动和轮胎质量不会产生影响；内模具的各零件的结构强度均满足设计要求。该研究可为阶梯式直压硫化内模具的工业化应用提供参考。
英文摘要:
      The structural strength of the stepped direct-pressure vulcanization inner mold（referred to as inner mold） for 225/40R18 tire was studied using Abaqus software.The results showed that under the vulcanization pressure of 4.6 MPa，the maximum stress in the inner mold occured on the wide drum tile wedge block slider，which was much smaller than the allowable stress of the slider material beryllium bronze.The maximum deformation displacement of the inner mold mechanism was 0.140 7 mm，and this deformation was elastic deformation，which would not affect the mechanism movement and the quality of the tire.The structural strength of each component of the inner mold met the design requirements.This study could provide a reference for the industrial application of stepped direct pressure vulcanization inner mold.
