The invention discloses a connector multidisciplinary collaborative design optimization method based on a self-adaptive proxy model, which comprises the following steps: constructing a Kriging initial proxy model, introducing an EI function to upgrade and construct the Kriging proxy model into the self-adaptive proxy model, and applying the self-adaptive proxy model to multidisciplinary collaborative design optimization. And constructing a multi-disciplinary collaborative design optimization method based on a self-adaptive agent model, performing uncertainty analysis and design optimization modeling on the special lifting appliance rotary platform connecting piece in a multi-physical field mechanical property coupling state, and finally performing design optimization. According to the method, the uncertainty theory, the agent model theory and the collaborative optimization theory are combined, so that the problem that a traditional design method is difficult to qualitatively and quantitatively construct optimization problem performance functions or constraint conditions for a complex engineering model, and wide application of a collaborative design optimization method in the field of practical engineering is restricted is solved; therefore, the lightweight target requirement of a special lifting appliance rotary platform connecting piece product is met.
