The Use of Imposed Displacements to Determine Impact Forces in a Multiple Blade Shed IncidentASME Journal of Engineering for Gas Turbines and Power
AbstractExperimental data from a multiple blade shed incident are used to determine the forces exerted by the blades on a containment ring. A transient, dynamic, finite element procedure is used to model the ring during the blade shed. This work focuses on the selection of the proper numerical parameters that lead to a stable and accurate numerical solution while maintaining physical reality. Examination of the degree of implicitness and various measures of damping, as well as incorporation of large displacement algorithms, has lead to a simulation that successfully determines the forces on the ring. Accurate determination of these forces is necessary for optimal design of containment systems.
