Computational and experimental assessment of the executive system dynamic properties in a space-based robotic complex

The paper presents results of vibration testing of the drive system target universal joint under the harmonic and random excitations. The finite element model was applied to obtain the torque computed assessment. At this torque, the executive system universal joint was breaking free during the vibration testing. The executive system finite element model was constructed and computed under the base harmonic excitation and damping level determined experimentally during vibration testing of the universal joint. Computational assessments of the universal joint torque of the head module under the executive system harmonic excitation were obtained.
