摘　　要：架桥汽艇顶推力自适应性研究是基于舟桥装备对汽艇顶推力大小能根据水流速度大小的变化而进行自动控制的研究。阐述了基于舟桥装备的浮桥系统的力学体系，根据原型装备和相似性理论研制了架桥汽艇顶推力自适应性试验模型，设计了汽艇顶推力自适应性的自动控制系统，并对处于试验环境下的模型进行受力分析，计算了50kg集中荷载和20kg均布荷载无偏距作用下的水阻力和轴间约束力，为汽艇顶推力自适应性试验提供了科学合理的水阻力、水流速间的函数关系式。The self-applicability research on the jacking force on the bridging boat （the force of bridging equipment to bridging boat）, is to study the jacking force auto-adjustability by the change of current speed. The mechanics system of floating bridge based on the pontoon bridge equipment is discussed. According to the prototype and the similarity theory, the self-applicability trial model of jacking force on the bridging boat is established, the auto-control system of the self-applicability of jacking force is designed. The forces on the model under experimental conditions are analyzed. The water resistance and sanction among the axles under 50kg centralized-load and 20kg equal-load are calculated. The scientific and reasonable function expressions for water resistance and water velocity are provided for the trial model of autoboat.
