Abstract
Systems and methods are provided for controlling the simulation of a coupled hybrid dynamic system. A physical test rig configured to drive the physical structure component of the system and to generate a test rig response as a result of applying a test rig drive signal. A processor is configured with a virtual model of a complementary system to the physical structure component. The processor receives the test rig response and generates a response of the complementary system based on a received test rig response. The system can be driven with a random input. The processor compares the test rig response with the response of the complementary system, the difference being used to form a system dynamic response model.
Core Innovation
The document describes an arrangement and method for controlling a coupled hybrid dynamic system comprising modeled components in a virtual model and physical components. A physical test rig drives physical structural components and generates a test rig response comprising a coupling response corresponding to an input to the virtual model and a convergence response that is compared to an output of the virtual model. A processor operates with storage to store a virtual model of a complementary system to the physical structural components, where the virtual model comprises a model of a disembodied assembly.
The processor obtains a virtual dynamic response of the virtual model of the disembodied assembly and obtains a combined virtual dynamic response for a plurality of disembodied assemblies. The processor obtains the system dynamic response model using the combined virtual dynamic response, the coupling response, and the convergence response.
For system-level modeling, the document further obtains a first dynamic response using the drive of the physical structural components and the coupling response, and obtains a second dynamic response using the drive of the physical structural components and the convergence response. A dynamic response matrix is obtained using the combined virtual dynamic response for the plurality of disembodied assemblies and the first dynamic response, and the system dynamic response model is obtained using the dynamic response matrix and the second dynamic response.
Claims Coverage
The partial content identifies two independent claims: an arrangement claim and a method claim, together describing a processor-based workflow that uses coupling response and convergence response from a physical test rig together with virtual dynamic response data for one or more disembodied assemblies to obtain a system dynamic response model. The independent claims include six inventive features covering both control/arrangement and method coordination steps, including combined virtual dynamic response for a plurality of disembodied assemblies and derivation of a dynamic response matrix.
Complementary virtual model linked to physical test rig responses
The arrangement includes a physical test rig configured to drive physical structural components and generate a test rig response comprising a coupling response corresponding to an input to the virtual model and a convergence response that is compared to an output of the virtual model, and a processor storing a virtual model of a complementary system to the physical structural components.
Combined virtual dynamic response for a plurality of disembodied assemblies
The processor obtains a virtual dynamic response of the virtual model of the disembodied assembly and obtains a combined virtual dynamic response for a plurality of disembodied assemblies using the virtual dynamic response for the disembodied assembly.
System dynamic response model from combined virtual response, coupling, and convergence
The processor obtains the system dynamic response model using the combined virtual dynamic response, the coupling response, and the convergence response.
Virtual drive and virtual dynamic response acquisition for disembodied assemblies
The method includes controlling the physical test rig to generate a test rig response comprising a coupling response and a convergence response, and applying a virtual drive to the model of the disembodied assembly using a processor to obtain a virtual model response and a virtual dynamic response for the disembodied assembly.
Dynamic response matrix construction using combined virtual response and coupling-based response
The method obtains a combined virtual dynamic response for the plurality of disembodied assemblies using the virtual dynamic response for the disembodied assembly repeatedly, obtains a first dynamic response using the drive of the physical structural components and the coupling response, and obtains a dynamic response matrix using the combined virtual dynamic response for the plurality of disembodied assemblies and the first dynamic response.
System dynamic response model from dynamic response matrix and convergence-based response
The method obtains a second dynamic response using the drive of the physical structural components and the convergence response, and obtains the system dynamic response model using the dynamic response matrix and the second dynamic response.
Overall, the independent claims cover obtaining a system dynamic response model for a coupled hybrid dynamic system by combining virtual dynamic response, including combined virtual dynamic response for a plurality of disembodied assemblies, with physical coupling response and convergence response, and by constructing a dynamic response matrix from the combined virtual dynamic response and a coupling-based dynamic response before using that matrix together with a convergence-based dynamic response.
