针对传统无杆牵引车夹持机构对飞机前起落架的自由度限制过多的问题,提出一种新型夹持机构模型,设计了虚拟样机,并采用Pro/E建模和ADAMSIN仿真的方法进行了三维建模、实体装配、干涉检查、仿真验证。结果表明该设计是合理可行的,为实体制作提供了重要依据。 Aiming at the problem that the conventional rodless tractor clamping mechanism has too much restriction on the degree of freedom of the nose landing gear, a new type of clamping mechanism model is proposed. The virtual prototype is designed and simulated by Pro / E and ADAMSIN Three-dimensional modeling, physical assembly, interference checking, simulation verification. The results show that the design is reasonable and feasible, which provides an important basis for the production of the entity.
