基于ADAMS的超长超宽梁架桥机行走系统仿真

随着公路桥梁施工需求的不断提升，超长超宽梁公路架桥机越来越多地应用在高速公路桥梁的架设施工过程中。针对一种宽度达10.9 m的超长超宽梁公路架桥机进行行走系统刚柔耦合仿真研究。通过对超长超宽梁公路架桥机的过跨过程进行步骤划分，并运用SolidWorks、ANSYS和ADAMS软件联合建立超长超宽梁公路架桥机行走系统的刚柔耦合虚拟样机模型并对其过跨过程进行仿真分析，得到架桥机行走系统主梁在过跨过程中的最大应力。通过分析主梁的应力情况得到主梁应力最大点发生在1号后支腿第二次前移过程中，应力最大值为162.4 MPa。该超长超宽梁公路架桥机行走系统刚柔耦合仿真可为后续改善施工规程、确定施工监测点、降低施工安全风险提供依据。

ADAMS-based Simulation on Traveling System of the Bridge Erector for Extra-long and Extra-wide Girder

With the increasing demand for highway bridge construction, the bridge erectors for extra-long and extra-wide girder highway bridge has been increasingly used in the process of highway bridge erection and construction. A rigid-flexible coupling simulation study of the travel system is conducted for a bridge erector for extra-long and extra-wide girder bridge with a width of 10.9 meters. By dividing the spanning process of the bridge erector for extra-long and extra-wide girder bridge into steps, and SolidWorks, ANSYS, and ADAMS software are used to jointly establish a virtual prototype model of the travel system of the bridge erector for extra-long and extra-wide girder bridge and simulate the spanning process, the maximum stress of the main beam of the bridge erector travel system in the spanning process is obtained. The maximum stress point of the main girder is 162.4 MPa during the second forward movement of the rear leg No.1 , which provides a basis for improving the construction procedures, determining the construction monitoring points, and reducing the construction safety risks.
