挖掘机性能分布的分形模型研究

Study on the Fractal Modes of the Excavator property Distri bution

应用分形理论研究了挖掘机性能分布的分形特征，测定出了挖掘机挖掘力、挖掘能力、整机重量、主电机功率等性能分布的分形维数，并推导出了相应的分形模型。实际应用的电算结果表明挖掘机性能分布具有较强的分形特征，其分形模型不仅能指导挖掘机的设计还能指导用户选型。

Based on the fractal theory. the fractal characteristic of the excavator property distribution is studied.and the fractal dimensions of excavating force. excavating capability.weight and power rating distributions of excavators are measured,then their fractal models are clerived. The result of computer computation of the actual application shows that the excavator property distribution has a stronger fractal characteristic, and the fractal models not only conduct the excavator design but also conduct the consumer to select the excavator type.
