林业机器人车轮与土壤相互作用力学性能仿真

Simulation on Mechanical Performance of Wheel Forest Soil Interaction in Forestry Robot

为了提高林业机器人在林区地面的行走性能,以东北林业大学帽儿山实验林场为试验地,在分析林区土壤力学特性基础上,依据车轮与林区土壤相互作用力的关系,建立了轮胎-林区土壤力学模型;应用力学分析软件,对林业机器人的车轮与林区土壤力学性能进行了仿真研究。结果表明:在现有结构和受力情况下,轮胎不会陷入林区土壤中。

In order to improve the walking performance of robot,taking Maoershan Forestry Experiment Station of Northeast Forestry University as an experimental site,we analyzed the interaction force between wheel and forest soil,and established a soil mechanics model of tire forest zone. A mechanical analysis software was used to simulate the soil mechanical properties of wheel forest in a forest robot. From simulation research,under the existing structure and force condition,the tires will not sink into the forest soil.
