摘　　要：采用ANSYS Workbench软件研究摩托车仿生花纹(以驼形花纹为例)沙地轮胎(简称驼形花纹轮胎)硫化温度场,并与普通花纹(长条形花纹和宽段形花纹)沙地轮胎进行对比分析。结果表明:3种花纹轮胎模具温模时间和温模后型腔温度基本相同,驼形花纹轮胎模具型腔温度差最小,温度差减小速度最快,传热最均匀;硫化900 s时,驼形花纹轮胎传热均匀性最好,可以保证一定的硫化均匀性;硫化1200 s时,驼形花纹轮胎各部位温度明显提升,上下胎肩温度差绝对值减小,传热均匀性更好;硫化1500 s时,3种花纹轮胎硫化效果相当,驼形花纹轮胎上下胎肩温度差绝对值进一步减小,传热均匀性进一步提升。The vulcanization temperature field of motorcycle bionic pattern(camel pattern as an example)sand tire(camel pattern tire for short)was analyzed with ANSYS Workbench software,and compared with the ordinary pattern sand tires(long strip pattern and wide section pattern).The results showed that the mold heating time and mold cavity temperatures after heating for all three types of pattern tire were basically the same;however,the temperature difference of the camel pattern tire mold cavity was the smallest,the temperature difference decreased the fastest,and the heat transfer was the most uniform.After being vulcanized for 900 s,the camel pattern tire had the best heat transfer uniformity,which could ensure better vulcanization uniformity.After being vulcanized for 1200 s,the temperatures of various parts of the camel pattern tire increased significantly,the absolute value of the temperature difference between the upper and lower shoulder decreased,and the heat transfer uniformity was better.When the vulcanization time reached 1500 s,the vulcanization effects of the three types of pattern tires were equivalent,but the absolute value of temperature difference between the upper and lower shoulder of the camel pattern tire was further reduced,and the heat transfer uniformity was further improved.
