基于细观离散元法的履带车辆转向阻力研究

Research on Steering Resistance of Tracked Vehicle Based on Meso Discrete Element Method

采用细观离散元法,通过土壤参数试验、履带板土槽试验及EDEM和RecurDyn协同仿真,对履带车辆与地面相互作用关系进行了分析,得到了履带车辆转向阻力(包括剪切阻力、摩擦阻力、刮土阻力)随转向半径和速度的变化规律.

Based on the meso discrete element method,the interaction between tracked vehicle and ground is analyzed through soil parameter test,track shoe soil bin test and EDEM and RecurDyn collaborative simulation.The variation rules of steering resistance(including shear resistance,friction resistance and scraping resistance)of tracked vehicle with steering radius and speed are obtained.
