The Stability Analysis Of The Autodumper And Its Cover Open Mechanism Optimization

With a large number of large construction projects have started, transportation has ushered inthe rapid development, the growing demand for the dump truck. Due to the special structure ofdump truck, and the operating environment is more serious, prone to instability and even roll.Therefore, the stability of the dump truck has become the important security issues that need to beresolved. As the people’s awareness of the environmental protection is increasinglyimproved,forcing the cover open mechanism becomes inevitable.Vehicle model on the basis of comprehensive consideration of the impact of the dump truckunloading operations rollover the main factors, first of all, UG three-dimensional modeling software.then, using ADAMS virtual prototyping software in the more objective, can truly reflect the site of aparticular model dump under the premise of the vehicle working conditions of its full load uphill,downhill fully loaded, side slope driving the level of road uninstall, uninstall climbing, maximumclimbing angle uninstall, side slope to uninstall the operating stability of the seven conditions ofsimulation analysis. finally, the cover open mechanism of autodumper uses optimization, so theopen angle will be bigger, and the force of the hydraulic cylinder will be smaller. According tothat,we provide a basis for the choice of the hydraulic cylinder.
