Research on Stability of Starting and Braking of Construction Machinery with Large Inertia Load
In order to solve the problem of starting and braking of construction machinery under high inertia loads,corresponding improvement methods are proposed.In response to the problems of impact,vibration,and stall that occur during starting and braking under high inertia loads,a combination of high-performance throttle valves and relief valves is used for system optimization.By precisely controlling the flow through a throttle valve,the actuator can achieve smooth acceleration and deceleration.The results show that the optimized hy-draulic system exhibits excellent starting and braking stability under high inertia loads.During the braking process of the excavator,there is no obvious impact,vibration,or stall phenomenon,and the system tempera-ture and pressure remain stable,which can solve the problem of smooth starting and braking of construction ma-chinery under large inertia loads.
