基于质量反应法的拖拉机质心高度测量方法

根据拖拉机前后轮直径不相等的特点，提出了基于质量反应法的拖拉机质心高度测量方法，建立了拖拉机质心高度计算理论模型。与本文提出的方法相比较，发现两轴道路车辆质心高度测量标准中质心高度计算方法可作为其中的一个特例。以江苏常发集团生产的CF650型拖拉机质心高度测量为例，对该文所提出的测量方法进行了试验验证和误差分析。分析结果显示其最大相对误差为0.34%。结果表明该文提出的方法测量精度能满足工程要求。

Determinationmethod of the height of tractors gravity center based on mass-response

Based on the characteristic that tractor front wheel and rear wheel have generally different diameters, a determination method of the height of tractor mass center on the basis of mass-response method was brought out and the corresponding theoretic calculating model was developed. By comparing with national standard of road vehicles with two axles, it was found that the theoretic calculating model given in the standard was only a special case of the model presented in this paper. This method was used for determining the mass center of the CF650 tractor produced by Jiangsu Changfa Groups and the maximum relative error was 0.34%. The result showed that this method for determining the height of mass center of tractor could satisfy the precision requirement of engineering.
