摘要:
针对北京市轨道交通新机场线对车辆技术参数的较高要求，对传统横向止挡结构刚度性能及抗疲劳性能进行分析，并提出了将外围金属与橡胶硫化粘结为一体的横向止挡优化方案。建立横向止挡的有限元分析模型计算其刚度，采用疲劳曲线，根据多应力和应变条件下的疲劳累积法则对优化后的横向止挡橡胶弹性体疲劳强度进行分析。仿真结果表明，优化后的横向止挡完全满足使用要求；试验结果表明，优化后的横向止挡刚度性能和抗疲劳性均满足使用要求。
Abstracts:
In view of the high requirements of Beijing rail transit new airport line on vehicle technical parameters, the performance of stiffness and fatigue resistance of conventional lateral buffer structure is analyzed, and an optimization scheme of lateral buffer is proposed, which integrates the peripheral metal and rubber by vulcanization and bonding. A finite element analysis model of lateral buffer is established to calculate its stiffness，then using fatigue curve and according to the fatigue cumulation rule under multistress and strain conditions, the fatigue strength of the optimized lateral buffer rubber elastomer is analyzed. The simulation results show that the optimized lateral buffer fully meets the operation requirements, and the test results show that the stiffness performance and fatigue resistance of the optimized lateral buffer meet the operation requirements as well.
