Abstract:
A special three-dimensional FMD (Force Measurement Device) is developed based on the study of the vertical force-limited control and the general three-dimensional FMDs. It is analyzed by the FEM and the vibration tests. Using the new three-dimensional FMD, a horizontal force-limited test is carried out for a certain satellite’s bearing cylinder. Test results show that the stiffness, strength, measuring range and accuracy of the new FMD can meet the requirement of vibration tests of the satellite of similar structures.
