Study on the Dynamic Model of Pole Machine Roll Stability

This paper takes the vertical vehicle as the research object to explore the common problems of engineering vehicles. On the premise of ensuring safety, the optimization model of the slope operation of the lever machine is established. The results show that the combination of counterweight (3t–4t) and force arm range (1.3m–1.7m) is better. In this way, the plane characteristics of each component are extended to the dynamic representation equation of the roll stability center of gravity under the dynamic load; Then the vehicle stability of the key parts of the operation arm and grip, The influence of the articulated steering angle, lateral acceleration and roll angle of the boom and grip is analyzed, At the grip hinge angle of 1°, When the flexion and extension length of the boom is (2 ± 0.3) m, The least impact on the car body; Based on the above work, This paper innovatively combines the characteristics of the engineering vehicle and the causes of roll instability, The influence of the vehicle steering Angle, body steering Angle, vehicle driving speed and the grasping load lifting Angle on the existing indicators is analyzed, And the roll angle stability index suitable for engineering vehicles, In the process of carrying engineering vehicles, The speed requirement is less than 8 m/s; When the turning angle is greater than 45°, The vehicle speed shall be reduced to 4 m/s, And as far as possible, the body and the turning direction of more than 11° to maintain the roll stability of the vehicle. The above research results can provide valuable reference for the subsequent research of the roll stability and the dynamic design of engineering vehicles on the pothole road.
