摘　　要：为满足检修要求,设计了一种可以在梁下旋转90°进而顺利通过桥墩和桥塔的轨行式桥检车,并运用多体动力学仿真软件ADAMS建立了整车虚拟样机模型,对其进行运动学分析,并完成了运动路径规划;然后,以3号变幅油缸最大受力最小化为目标,对油缸铰点参数化处理并进行敏感度分析,通过优化油缸铰点位置优化油缸受力。研究结果表明:优化后的铰点位置改善了变幅油缸的受力状况,油缸最大受力减小4.17%。该方法可为类似机构的优化设计提供参考。In order to meet the maintenance requirements,a rail-mounted bridge inspection vehicle that can rotate 90°under the beam to smoothly pass through the piers and pylons is designed,and a virtual prototype model of the vehicle is established by using the multibody dynamics simulation software ADAMS,kinematics analysis is carried out,and the movement path planning is completed;then,with the goal of minimizing the maximum force of the No.3 luffing cylinder,the cylinder hinge points are parameterized and the sensitivity analysis is performed,and the cylinder force is optimized by optimizing the cylinder hinge point position.The research results show that the optimized hinge position improves the force status of the luffing cylinder,the maximum force of the cylinder is reduced by 4.17%.This method can provide a reference for the optimization design of similar mechanisms.
