【摘要】 作为农业机械、建筑机械、工程机械等机械运载底盘,橡胶履带底盘对实现市政基础建设机械化,农田、沙漠、沼泽地等松软地面的作业和运输具有积极意义;极大地扩展了履带式和轮式行走运输机械的应用范围,克服了各种不利地形条件对机械作业的制约。论文在分析国内外橡胶履带底盘发展、橡胶履带结构形式与履带底盘行走机构的基础上,对橡胶履带底盘行走机构建立力学分析模型,应用理论力学、岩土—机器系统动力学,对履带行走机构的行驶阻力、接地比压分布和履带行走机构的附着性能进行理论分析与实验研究。为了深入了解橡胶材料的耐磨特性等,采用8种耐磨橡胶材料和8种不同粗糙度的供试路面。对硬度相同,但原材料不同的橡胶,考虑硬度以外的物性对磨损产生的影响;对原材料相同,但硬度不同的橡胶,考虑硬度对磨损的影响;调查路面粗糙度的影响。本文尝试采用高端软件的研究方法,对橡胶履带结构进行力学分析和强度校核进行仿真设计分析,以确认本文前述理论分析的正确性。并将分析结果与前述几章理论分析结果进行比较。更多还原

【Abstract】 As machine haulage chassis of agricultural machinery, construction machinery and engineering machinery, the rubber-tracked chassis have a positive significance for the mechanization of municipal infrastructure and the surface softening and transport of farmland, desert, swamp and so on. It has greatly expanded applications of tracked and wheeled walking transport machinery and overcome a variety of mechanical operation constraints of adverse terrain conditions.Based on the analysis of the development of rubber-tracked chassis, the structure of rubber track and the running gear of tracked chassis, this paper elaborates theoretical analysis and experimental research on the establishment of mechanical analysis model of running gear of rubber-tracked chassis, applications of theoretical mechanics, ground-machine system dynamics, driving resistance of running gear of tracked chassis, ground pressure distribution and attachment performance of crawler.To better understand the wear-resisting property and other properties of rubber material, eight kinds of wear-resistant rubber material and eight tested roads of different roughness are used. For the rubbers made of different raw material with the same hardness, physical properties other than hardness of impact on the wear and tear are considered, the other way round, the impact of surface roughness on the road is investigated.In this paper, in order to confirm the theoretical analysis mentioned above, a high-end software is used for the simulation, design and analysis of the structure of the rubber-tracked chassis and the checking of intensity, and the results of the analysis is compared with the results of theoretical analysis of previous chapters.更多还原
