有轨电车头罩粘接结构的有限元仿真分析
|
摘要
对某型号有轨电车头罩部位的粘接结构进行了有限元仿真分析,按照DIN 6701-3:2015-12《轨道交通车辆及车辆部件的粘接-第3部分:轨道交通车辆粘接接头的设计及验证指导手册》标准的要求,得出了该粘接结构在不同载荷工况下的应力应变情况,并与对应的载荷极限进行比对,从而系统验证了该粘接接头在整个产品寿命周期内的可靠性。基于仿真结果对于应力集中的粘接部位给出了相应的结构优化建议。
The finite element analysis of the bonded structure of the front head of a certain type of tramcar was carried out. According to the standard requirements of DIN6701-3《 Adhesive bonding of vehicles and parts, Part 3.Guideline for construction design and verification of bonds on railway vehicles》,the stresses and strains of the bonded structure under different load conditions were calculated. And compared with the load limit, so the reliability of the bonded joint over the product life cycle was systematically verified. Based on the simulation results, corresponding structural optimization suggestions were given for the bonded structures with consideration of stress concentration phenomenon.
