Verification of static strain and deformation of industrial robot actuator in ANSYS environment

The article describes the process of experimental analyses in verifying the static strain and deformation of industrial robot actuator. The experiments were carried out in ANSYS analytical system environment. The actuator body behaviour has been verified with respect to its required high accuracy when subjected to radial, axial and torque loads. Due to load, high pressures and consequent partial or total deformation of body, which may result in a deviation in hundreds of millimetres. In case of unsatisfactory results, it is necessary to modify body actuator from structural point of view, either by adding a layer of material to weakened surfaces or by changing the holes layout and functional holes of the actuator. The results were compared with prescribed values of slope of selected material. In first phase of the experiment, forces were applied individually to the body, next one being experimented with their concurrent action.
