YZ18振动压路机后车架设计及整机分析+CAD图纸
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

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 .
