应用热弹性力学理论和有限单元法对滑板在服役期间的实际应力情况进行计算 .通过对滑板砖一次成形工艺和二次成形工艺的应力分析比较得出结论 :在外部材料能够满足性能要求的前提下 ,与一次成形工艺比较 ,二次成形工艺更能发挥材料特性 ,提高滑板的抗热震性和耐用性 Based on the theory of thermoelasticity and the finite element method, the actual stress of the skateboard during service is calculated.By comparing the stress analysis of the skateboard brick once forming process and the secondary forming process, the conclusion is drawn that in the premise that the external material can meet the performance requirements , Compared with a forming process, the secondary forming process can better exert the material characteristics and improve the thermal shock resistance and durability of the skateboard
