Finite Element Simulation and Experimental Research on Curing Process of Laminated Rubber Isolation Bearings

通过橡胶硫化热传导方程和硫化动力学模型建立叠层橡胶隔震支座硫化工艺有限元仿真模型。通过支座硫化热电偶测温试验,验证了所建有限元模型的正确性。该有限元模型可用于橡胶支座硫化工艺的制定和优化。通过有限元模型对支座是否采用预热处理及是否采用辅助加热等4种硫化方案进行数值模拟,发现对支座进行预热处理比辅助加热更能有效地提高硫化效率。

Based on the equation of heat conduction and curing kinetics model,the finite element simulation model on the curing process of laminated rubber isolation bearings was established. The results of thermocouple temperature test verified the validity of the established finite element model,so the model could be used in the design and optimization of the curing process. Four curing schemes in which the variables were whether the bearings were preheated and whether auxiliary heating was used were simulated by using the finite element model. It was found that the preheating of bearings could improve the curing efficiency more effectively compared with the use of auxiliary heating.
