摘　　要：以目前国外盾构普遍采用的三排滚柱式大轴承作为研究对象,结合盾构大轴承受力特点和大轴承设计方法建立参数化优化模型。以成都地铁所用的盾构为例,在满足设计要求的额定静载荷条件下,建立优化模型并利用Matlab优化工具箱求解。结果表明通过该方法能够有效确立大轴承的滚柱数量和尺寸,研究对大轴承的国产化有一定的积极作用。Taking the three rows,cylindrical roller type,big bearing widely used on shields abroad as research objective,a parametric optimization model is set up in association with loading characteristics of big shield bearing and its design method.Taking the shield in Chengdu subway construction as an example,optimal model is established under the condition of rated static load satisfied and Matlab optimal tool is applied to solve the model.The results show that the roller number and dimensions can be determined effectively with the method and the research features a positive role in the localization of big bearings.
