YL25型轮胎压路机悬挂系统设计+CAD图纸
本文YL25型轮胎压路机悬挂系统设计，依据徐工集团生产的YL25型轮胎压路机相关应用数据，在对整体悬挂系统分析过程中，蓄能器的初始体积、初始压力以及悬挂缸的活塞杆直径等因素对悬挂系统的影响较大，在通过AMESim对油气悬挂进行建模，以及建立悬挂的数学模型后，可对悬挂的各个影响因素进行仿真分析，不断改变各个参数的值，会得到不同的参数变化函数曲线，通过分析曲线的变化规律得出相应的结果。34820
通过仿真分析，优化了原有尺寸的部分数据，对压路机的性能有了很大的改进，延长了压路机的使用寿命。

Design of suspension system in tire roller of YL25
[Abstract]Hanging directly affects the performance of the whole machine stability and comfort, the traditional fixed suspension stiffness, and in the actual road conditions, the laser shock signal road has been changed, so the traditional hanging unable to meet the whole of the suspension stiffness can change, automatically adjust the height requirements, and roller suspension a significant impact on the situation of pavement compaction, if the traditional suspension will result in uneven pavement compaction, etc., so this scheme uses a pneumatic suspension.
This article YL25 Tire roller suspension system design, based on the production of YL25 XCMG tires roller related applications data, the overall suspension system analysis, the initial volume of the accumulator, the initial pressure and suspension cylinder rod diameter and other factors on larger impact suspension, after oil and gas suspension by AMESim modeling and mathematical model suspension can be suspended on various factors simulation analysis, changing the value of each parameter will be a function of different parameters change curve analysis by variation curve corresponding results obtained.
Simulation analysis and optimization of the part of the data of the original size of the roller's performance has been greatly improved, extending the life of the roller.
