Abstract

Transformation of the original theoretical load into the testing implementation load is necessary in the ground structure strength test, the results of which directly determine the authenticity and validity of the test. The traditional load transacting method compares the numerical analysis results after load transaction based on load equivalent, and the efficiency and accuracy of this open-loop control method are often reduced significantly when encountering complex structures and loads. We propose a testing load transaction method based on the assessment target equivalent, and combine the numerical simulation analysis with the load transacting process. A closed structure of load optimization, testing state simulated analysis and assessment target evaluation is established. The structural target response is taken as the evaluation criterion and optimization objective. Using the sensitivity analysis and genetic algorithm, this method significantly improves the efficiency and accuracy of load transacting. Furthermore, we develop load transacting software based on the MATLAB GUI platform, implementing a variety of functions modularized, such as the sensitivity analysis, load-response matrix calculation, and load optimization design. This method is then applied to the elevator structure load transacting process, realizing precise control of the assessment target error in the load transacting process.
