Description
Summary:The paper provides a procedure for experimental determination of loading to which elements of kinematic pairs (Joints) of the kinematic chain and drive mechanisms in an excavating manipulator of hydraulic excavators with continuous tracks are subjected. A mathematical model is defined to enable the determination of force and moment vectors of joints loading, on the basis of the measured quantities of the excavator state during the operation in exploitation conditions. The measured quantities of the excavator state relate to the position of the kinematic chain and the pressures of the hydraulic system in the ducts of the excavator drive mechanisms actuators. As an example, the paper provides research results obtained during experimental determination of loading of kinematic pairs (Joints) in a hydraulic excavator of 17,000 kg in mass.
