Working Condition Analysis and Performance Calculation of Tracked Unmanned Aerial Vehicles Based on MBD

针对履带式无人疏浚机械在典型工况下的疏浚承载特点,采用“基于模型的产品定义”和本体理论,通过有限元静力分析确定整车载荷及边界条件,进行了4种典型工况的仿真计算,分析了水下无人疏浚机械在4种典型工况下各零部件变形和应力分布情况。结果表明,几何信息、材料信息、工艺信息关联映射下的水下无人疏浚机械整体性能满足目标工况设定需求。

Mechanical force characteristics of tracked unmanned aerial vehicles under typical dredging conditions is focused.Adopting model-based product definition and ontology theory.Determine the vehicle load and boundary conditions.Four typical operating conditions were simulated and calculated.Analyzed the deformation and stress distribution of each component of underwater unmanned dredging machinery under four typical working conditions.The results indicate that the overall performance of underwater unmanned dredging machinery under the correlation mapping of geometric information,material information,and process information meets the requirements of target operating conditions.
