Wheel loader Digging process Track planning Saving energy Simulation
为给装载机的铲掘作业寻找一条能耗较小的铲掘轨迹,根据经验及有关文献给出的较理想的直线和曲线两种铲掘作业的轨迹方程,经过对装载机铲掘作业的轨迹规划及运动学建模,实现铲掘轨迹由直角坐标空间向关节空间转换以及由关节空间向驱动空间转换,得到动臂油缸和转斗油缸的驱动方程,并给出铲斗在实现铲掘轨迹的过程中所受的作用力.对在ADAMS环境下ZL40装载机仿真模型进行仿真,结果表明,装载机在同样时间内完成同样的作业量下,直线铲掘轨迹所作的总功小于曲线铲掘轨迹.
為給裝載機的鏟掘作業尋找一條能耗較小的鏟掘軌跡,根據經驗及有關文獻給齣的較理想的直線和麯線兩種鏟掘作業的軌跡方程,經過對裝載機鏟掘作業的軌跡規劃及運動學建模,實現鏟掘軌跡由直角坐標空間嚮關節空間轉換以及由關節空間嚮驅動空間轉換,得到動臂油缸和轉鬥油缸的驅動方程,併給齣鏟鬥在實現鏟掘軌跡的過程中所受的作用力.對在ADAMS環境下ZL40裝載機倣真模型進行倣真,結果錶明,裝載機在同樣時間內完成同樣的作業量下,直線鏟掘軌跡所作的總功小于麯線鏟掘軌跡.

To seek a track which consumes less energy for a wheel loader in a digging process, the track equations of two kinds of ideal tracks, a beeline and a curve, are given according to experience and relevant literature. The tracks are transformed from fight-angle-space coordinate to joint-space coordinate, and from joint-space coordinate to drive space through track planning and kinematics modeling for the type of ZL40 wheel loader in a digging process. The drive equations of the lift cylinder and tilt cylinder are obtained. The force acting on the bucket in a digging process is given. A simulation for the ZL40 wheel loader model is presented in ADAMS software. The simulation result shows that the beeline track consumes less energy than the curve track does while the same load is completed in the same time.
