摘  要:
通过Pro/E软件建立弧形深松铲切削土壤的三维模型,在ANSYS Workbench中对模型进行有限元前处理,并生成K文件,在LS—PrePost软件中对K文件进行修改,生成仿真所需SPH粒子模型,选择MAT 147号材料模型作为土壤,运用SPH/FEM耦合方法进行土壤深松进行动态仿真,仿真结果达到试验预期,为土壤深松数字化设计提供新的方法。

摘  要:
A three-dimensional model of subsoiler was constructed through Pro /E software,the finite element pre-processing was conducted on the model in ANSYS Workbench,K file was obtained and was modified in the LS-PrePost software,generating the required SPH particle simulation model. Choosing MAT No. 147 material model as soil,dynamic simulation was conducted on soil deep loosening by using SPH /FEM coupling method. The simulation results achieved the experimental expectation,which will provide a new method for soil deep loosening digital design.
