  • Test method, test rigs and control system
    Patent number: 9354149
    Abstract: A method for load relieving a test object, wherein a load is applied by a multiplicity of hydraulic devices positioned side by side each introducing a partial load into the test object such that the test object has a minimum deflection in an area close to its fixation and a maximum deflection in an area far away from the fixation, wherein the load is reduced sequentially from the maximum deflection to the minimum deflection. A test rig is provided that enables an autonomous and non-synchronical load relief of a test object based on pressure difference. A test rig is provided that enables an autonomous and non-synchronical load relief of a test object based on a delay time and a control system for such test rigs.
