Function reliability analysis method for ship distance adjusting mechanism based on proxy model technology

The invention relates to a ship distance adjusting mechanism function reliability analysis method based on an agent model technology. The method comprises the following steps: (1) creating an initial sample space of uncertain design variables of a ship distance adjusting mechanism; (2) uncertain parameter analysis is conducted on the pitch adjusting process of the controllable-pitch propeller; (3) establishing a rigid-flexible coupling parameterized model of the distance adjusting mechanism, and parameterizing design variables; (4) performing multi-body dynamic simulation in the ADAMS, calculating to obtain angular displacement of rotation of the five blades, and taking the five dynamic response quantities as target response; (5) the initial sample space of the uncertain design variables of the ship pitch adjusting mechanism is substituted into the multi-body dynamics simulation in the step (4), a target response interval of the pitch adjusting mechanism is obtained, and the initial sample space and the targe
