Analysis and optimization for driving stability of large tonnage articulated dump truck in coal mine
WANG Qing-xiang
Abstract:The driving stability of coal mine large-tonnage articulated-frame dump truck is reduced by heavy load,large shape,higher gravity center.In view of the above problem,the evaluation index of “stable angle” is put forward to evaluate and optimize the stability.And stability criteria are developed according to the operating conditions in the underground tunnel of the vehicle.The analytical formula of stable angle is derived by establishing the geometric modal of vehicle horizontal and second-level instability,the stability angle was calculated by MATLAB software,the parameters of the wheelbase,wheelbase,rolling radius and gravity center position are optimized because of the horizontal one stable angle does not satisfy the criterion.By the calculation,The lateral horizontal one stable angle of the optimized design meets the requirement of stability criterion,the rest of stable angle indicators also increased by about 10%.
