Optimization of the Parameters of a Hydraulic Excavator Swinging Mechanism

The presented paper is focused to the optimization of the parameters of a hydraulic excavator swinging mechanism. A trapezoidal velocity profile is considered for rotation of the excavator platform to the predefined angle. Equations for the torque and power, needed to rotate the platform according to the prescribed trapezoidal trajectory are derived. The maximum values of the driving torque and power are optimized.
