The modal analisis of a two-link mechanical system of a robot manipulator

Abstract

The method of calculation of natural frequencies and forms of oscillations of a two-link mechanical system of a robot manipulator is proposed. Links of the system are considered as straight rods with a step change of cross-sectional parameters. The equations of motion of a mechanical system are based on the technical bending theory. The analysis of oscillation processes is carried out using the matrix method of initial parameters.

“…When transferring torque from the gearbox (gear box) to the gearboxes of the driving wheels, it is necessary to ensure the mutual movement of the nodes, taking into account the fluctuations of the power unit and the movement of the gearboxes, when the car is moving. For this purpose, crosspieces [1,2,3,4,5] are used, which provide the transmission of torque when the shaft elements are deflected by 15 degrees. The crosspiece connects two forks pivotally; at the same time, the spikes of the crosspiece enter the holes of the forks.…”
