Assessment of the Stability of Bev Lhd Loader

Abstract The article concerns the computational model for analysing stability of BEV LHD loader. Works were carried out to develop an innovative, light battery-powered loader, which was subject R&D project implemented in cooperation with Bumech S. A. Compared existing solutions loaders similar load capacity, this one is distinguished by use individual electric drive each wheel and a replaceable battery. A physical mathematical developed taking into account specificity In model, masses battery, drives, platform excavated material are taken separately. allows determining loader pressure on floor, depending location its components’ centres gravity, turning angle machine, amount bucket position bucket. input parameters also include longitudinal transverse excavation slope angles. addition, enables inner outer radius To verify theoretical dynamic simulation tests out. results analyses confirmed correctness model. used prepare calculation sheet basis adopted parameters. article, selected conducted have been presented, along proposed ensuring loader’s stability. quick assessment stability, which, due number innovative solutions, differs from designs. structure at design stage numerous modifications, affect distribution gravity components. useful, parameterized tool that assessing values radii machine.
