推土机性能分布的分形模型研究

STUDY ON THE FRACTAL MODEL OF BULLDOZER PERFORMANCE

应用分形几何理论，研究了推土机性能分布的分形特征。根据现有主要推土机性能数据测定出了推土机推土速度、牵引力和重量分布的分形维数，并推导出相应的分形几何模型。电算结果表明，推土机性能分布具有较强的分形特征，而且在实际应用中其分形维数和分形模型是有效的。

The fractal characteristic of the bulldozer performance distribution is studied with the fractal theory.The fractal dimensions of bulldozing velocity,pulling force and weight distribution are measured according to the performance data of main bulldozers,and their fractal models are derived.The result of computation shows that the bulldozer performance distribution has stronger fractal characteristic,and the fractal dimensions and models in actual application are effective and practicable.
