Influence of critical turning speed of pure electric mining dump truck on rollover and sideslip

Because vehicles often violate the speed limit on curved roads, rollover and sideslip accidents occur on curved roads frequently. Designing the speed limit value of the curve road is an important measure to improve the driving safety of vehicles on curved roads. Considering how sharply the mine road turns, the safe driving speed of vehicles on curved roads is proposed in this paper based on the critical state of vehicle rollover and sideslip. Through the dynamic analysis of the vehicle curve driving, the relationship between the maximum speed limit of the curve and the parameters such as the lateral slope, the lateral force coefficient, and the turning radius under different curve radii is discussed to avoid lateral sideslip when the vehicle is driving on the curve. The curve road's speed limitation under each parameter's influence is obtained by changing the relevant parameters.
