Calculation and Research of Structural Behaviors on Existing Continuous Steel Truss Bridge under Heavy Trailer Load(TL) 既有连续钢桁梁桥当重车过桥时结构性能的计算研究
First, road roughness is simulated in the time domain, and then the 3-axle vehicle and the 4-axle trailer models are established for the study of vehicle dynamic load. 首先,对路面不平度进行时域模拟,进而建立三轴和四轴拖挂车车辆动力学模型,并以此作为车辆动载荷分析的基础。
The important problems demanding prompt solution in manufacturing trailer mounted pumping units on a large scale include working out relevant standards as soon as possible, selecting proper trailer chassis, decreasing the deadweight of the mast and improving its load capacity. 尽快制定相关标准,筛选适合工艺要求的汽车底盘,降低井架自重并提高其承载能力等,是规模生产捞油车亟待解决的主要问题。
The overall structure of the program with the novel model, and the application of semi-trailer with the past and all wheel steering trailer can lift 100 tons compared to more flexible use of a wide range of host large tonnage, load distribution more reasonable. 该车型整体结构方案构思新颖,与国内过去应用的半挂车和全轮转向可升降式百吨全挂车相比,更加灵活、使用范围广、承载吨位大、载荷分布更为合理。
