摘　　要：工作臂架及吊篮是伸缩臂式高空作业车工作装置的主要构件,它所受到的荷载十分复杂,对强度要求极高。结合高空作业车的实际工况,提出产品整体性能优化设计方法,基于该方法建立工作臂架第3节臂及吊篮的整体有限元模型,对其最不利工况进行有限元分析,得到应力分布。结合分析结果提出高空作业车第3节臂及吊篮整体性能最优的改进方案。Working arm frame is one of the main working parts of telescopic-arm high-altitude operation-car,which endures complicated loads and demands high strength. A performance-optimization method for integrated structure of product was presented based on the actual working conditions of the telescopic-arm high-altitude operation-car, then a 3D finite element analysis model by taking the third working arm frame and basket as a whole was built to analyze stress distribution in the worst working condition. Finally, the best solution for the whole performance optimization of high-altitude operation-car was found.
