升降辊床连杆摇臂结构拓扑优化设计
|
摘要
升降辊床作为一种新型输送设备,具有高速、稳定、易于维护等优点,在各汽车焊装车间得到了广泛应用。文章对辊床连杆摇臂结构进行动力学分析,在此基础上针对摇臂结构进行结构拓扑优化,改善机构应力应变并提升疲劳寿命。
As a new type of conveying equipment, lifting roller bed has the advantages of high speed, stability, easy maintenance and so on. It has been widely used in various automobile welding workshops. Based on the dynamic analysis of the rocker arm structure of the roller bed connecting rod, the topology optimization of the rocker arm structure is carried out to improve the stress and strain of the mechanism and to enhance the fatigue life of the rocker arm.
