The application provides a transmission high-low temperature cycle endurance test method and
system, which comprises the following steps: collecting basic parameters, key parameters and implicit parameters of the transmission at a
physical layer through a dual-mode sensing unit, mapping a
physical test state through a digital twin model at a virtual layer to generate a virtual sensing
feature set, and corresponding integration into a dual-mode sensing feature
tensor; calculating a dynamic
adaptation degree between a test requirement
feature matrix and the dual-mode sensing feature
tensor in real time through a preset multi-field
coupling feature
discriminator, generating a three-dimensional composite feature map based on the dynamic
adaptation degree; constructing a virtual-real linkage adaptive test framework according to the three-dimensional composite feature map; extracting target data from the dual-mode
sensing data and the test
requirement document and filling it into the corresponding analysis sub-column, synchronously passing through the
coupling correlation path in the three-dimensional composite feature map to complete the corresponding endurance test. The application can comprehensively and accurately complete the endurance test, and the
test efficiency is improved.
