The center of gravity trajectory during the operation of a large device determines the stability of the entire machine. In response to the problem of structural instability caused by changes in the center of gravity during the operation of reclaimer, this paper proposes a method for modeling and simulating the center of gravity trajectory and evaluating the stability health under variable load conditions. The model and method are validated using wheel pressure tests on the reclaimer. By reconstructing the local structure of the model and updating its parameters, the changes in the center of gravity trajectory of the entire machine under the current state are obtained. Using the center of gravity trajectory of the machine after initial installation as a reference, the structural stability of the reclaimer under current conditions is evaluated for health, thereby avoiding accidents caused by center of gravity issues during operation.
