The invention relates to a simulation testing method for dangerous working conditions of a portal crane. The simulation testing method comprises the steps S1, actual structural size data of all partsof the crane are obtained so as to build three-dimensional geometric models of the crane; S2, the geometric models of the crane are correspondingly transformed into ADAMS virtual prototype models; S3,according to different dangerous working conditions, the ADAMS virtual prototype models are subjected to corresponding simulation testing, and the simulation running data of the crane under differentdangerous working conditions is obtained; S4, according to the simulation running data of the crane under different dangerous working conditions, the corresponding results of stress changes, movementconditions and overturning tendencies are obtained. Compared with the prior art, the three-dimensional geometric models are built by using the key parts of the portal crane, and in the combination ofthe virtual prototype technology, the problem that field testing of the dangerous working conditions of the crane are difficult to conduct is solved, and the results of the stress changes, movement conditions and overturning tendencies of the crane under the dangerous working conditions conforming to the actual situations can be quickly and accurately obtained.
