WORKING AREA CALCULATING METHOD FOR EXCAVATOR

摘要

PURPOSE: An excavator work area calculation method is provided to calculate an optimal horizontal excavation distance and vertical excavation depth, thereby excavating a large amount of soil without the ground collapsing. CONSTITUTION: An excavator specification and the amount of soil are inputted, and an initial value of vertical excavation depth is set(S11). A virtual plane breaking surface and soil wedge weight are calculated in the vertical excavation depth, and the initial value of excavator weight located in a soil wedge area is set(S14). When the virtual plane breaking surface is broken by partial excavator weight, a bucket area sectional section is calculated and stored by using horizontal and vertical excavation depths before the virtual plane breaking surface is broken.
