Method and system using pre-qualified reference data in vibration system

A testing system for testing a test specimen, the testing system comprising:

• an actuator couplable to the test specimen to apply forces to or displace the test specimen of portions thereof;
• sensors for providing outputs of measured parameters of the test specimen or the actuator;
• memory having pre-qualified reference data;
• a display;
• and
• a controller coupled to the memory and the display and configured to control the actuator using drives and configured to receive associated responses comprising the outputs from sensors and wherein the controller is configured to
• derive a first drive by applying successive test drives to the physical system and comparing associated received responses until associated received response suitably corresponds to a desired response;
• render on the display one or more acceptable first limit values associated with each of the outputs of the response, the one or more acceptable first limit values being based on a pre-qualified reference values in the pre-qualified reference data for each output;
• generate the first drive using the controller and apply the first drive to the actuator;
• receive a first response from the sensors;
• for each output of the first response, comparing a received value with the associated one or more first limit values;
• identify to the operator on the display one or more outputs having a value violating one or more of the acceptable first limit values for the associated output of the first response;
• identify that at least one pre-qualified reference value is to be replaced with a value from the first response;
• replace each pre-qualified reference value with each associated value from the first response or subsequent responses when each associated value does not violate each associated first acceptable limit value;
• store the associated values as a qualified reference file;
• and
• use c during testing of the test specimen to monitor the test and/or detect trends during the test.
