陆用地震勘探系统中橡胶履带装置的研究

摘要

The big drag force of the rubber track traveling mechanism exists in the large scale towed seismic exploration system.According to the terramechanics of track vehicle,this paper presents a new type of rubber track with lateral flow limiting blocks and grousers with inclined plane and groove and establishes its finite element simulation model.Through the finite element simulation analysis,it is verified that the new rubber track with limited lateral-flow of soil can be used to improve the shear strength of soil and effectively reduce subsidence of the track and its drag force.%陆用大型拖曳式地震勘探系统中存在履带行走机构拖曳阻力大、拖曳时履带不转动的问题,研究利用地面力学的原理,提出了一种具有侧向限流块和带凹槽倾斜面履刺的新型履带,并建立了该新型履带与地面相互作用的有限元仿真模型,通过有限元仿真分析,验证了该新型履带具有侧向限流和提高土体抗剪强度的作用,可以有效地减少履带的下陷,从而降低拖曳阻力并解决橡胶履带不转动的问题.
