METHOD OF OFF-LINE HYBRID SYSTEM ASSESSMENT FOR TEST MONITORING AND MODIFICATION

摘要

A method and apparatus for controlling the simulation of a coupled hybrid dynamic system (70, 72) comprising a part under test (80) and a virtual model (80) comprises an initial test drive signal input (114) to a test rig (72). It involves driving the physical component under test 80 of the system over a period of time to perform the test by applying to generate a test rig response. At least a portion 94 of the test rig response is input into a virtual model 70 of the system to obtain a model response 100 of the system. The condition of the physical component under test 80 is evaluated based on a comparison of the model response 100 with another portion 96 of the test rig response for at least a portion of the time period during which the test is being performed, wherein an output related to this evaluation is recorded. or is presented
