| 摘要：我国压路机，整体技术水平与国外相比仍有差距，主要表现在：产品型号不全、重型和超重型压路机生产数量和品种仍然较少、专用压实设备缺乏、综合技术经济指标和自动控制方面仍低于国外先进水平。本文意在研究压路机后车架的相关参数和结构设计，以及前后车架铰接并对压路机整体的稳定性进行分析，使其能够达到所需的工作状态，通过研究缩短与国外的差距。 通过理论分析计算和实物参考，本文完成了YZ18振动压路机的后车架设计以及整体稳定性的分析，确定其基本参数，前后车架的铰接以及后车架的造型设计是设计的主要部分。铰接通过转向阻力矩以及行驶阻力矩计算，并通过计算中间轴承的剪切力和弯矩，最终计算得出铰接销的尺寸，并对轴承等进行校核。而整体稳定性分析也通过坡道和行驶的稳定性分析，最终得出结论。19962 关键词：振动压路机；后车架；驾驶室；机罩；铰接 Design of vibratory roller rear frame and machine analysis Abstract : Our roller , the overall technological level is still a gap compared with foreign countries , mainly in : Model insufficiency, heavy and super heavy-duty roller production quantity and variety is still small, the lack of special compaction equipment , comprehensive technical and economic indicators and automatic control remains lower than the international advanced level . This paper is intended to frame the relevant parameters and structural design , as well as the overall stability of the front and rear hinged frame and roller compactor after study analyzed so that it can achieve the desired working condition through research shorten the gap with foreign countries. Computing and in-kind reference , this paper analyzes completed after YZ18 vibratory roller frame design and overall stability , determine the basic parameters before and after the frame is hinged frame design is a major part of the design of the theoretical analysis . Articulated steering resistance moment by moment , and the running resistance calculated by calculating an intermediate bearing shear forces and bending moments , the final calculated size of the hinge pin , and be checked bearings. The overall stability of the slope stability analysis and also traveling through the analysis of the final conclusion .
