摘　　要：拱顶储罐内壁板防腐自动化施工装备是一种新型设备,其多节桁架结构长细比较大,柔性增加,其稳定性成为能否满足安全生产的重要指标。针对多种工况,利用ANSYS软件建立该装备整机结构的有限元模型并进行运动仿真分析,其应力和形变均在安全范围内,整机结构满足强度和刚度要求。通过力学计算进行整机结构抗倾覆稳定性分析,校核结果表明,该装备具有很强的抗倾覆能力,能够满足现场施工对稳定性和安全性的要求。The automatic anticorrosion construction equipment for the inner wall plate of the vault storage tank is a new type of equipment.Due to the large slenderness ratio of its multi-section truss structure and the consequent increased flexibility,its stability is an important indicator of whether it can meet the requirements of safe production.With consideration of various working conditions,a finite-element whole machine structure model of the equipment was built with the ANSYS software,and motion simulation analysis was carried out.The results showed that the whole machine structure met the strength and rigidity requirements,with its stress and deformation both within the safe range.The anti-overturning stability of the whole machine structure was analyzed by mechanical calculation.The stability check results indicate that the proposed equipment has a strong anti-overturning ability and can meet the requirements of the construction site for stability and safety.
