Position and static force analysis of a backhoe excavating equipment

Mitrev R.

Nr 8

81-92

In the present study are suggested and developed new computer oriented algorithms for position and static force analysis of a backhoe excavating equipment. The position analysis is based on matrix description of the position of the bodies, which forms the open kinematic chain. The fol-lowing-up static force analysis is used for determination of the static reactions in the joints. It is performed by composition of static equilibrium conditions for each body and solution of the received system of linear algebraic equations. The developed approach is realized and automated in interactive MathcadŽ program PSAB 1.0 (Position and Static force Analysis of a Backhoe excavating equipment).

This article presents a theoretical method of calculation of the pressure distribution in pumps with canned rotor and thrust resulting from hydraulic forces (of the pump) and from the static forces (of the motor). The calculations were validated by the experiments undertaken in industrial conditions.
