The invention discloses an equivalent fuel assembly for fuel storage grillwork anti-vibration test. The equivalent fuel assembly for the fuel storage grillwork anti-vibration test comprises a lower pipe base, a grillwork group, an upper pipe base, a gauge pipe simulated stick group and a fuel stick simulated stick group; the gauge pipe simulated stick group is fixedly connected with the upper pipebase and the lower pipe base; the fuel stick simulated stick group penetrates through a through hole in the grillwork group and is freely placed in a groove of the lower pipe base; the grillwork group is fixedly connected with the outermost ring of fuel stick simulated stick of the fuel stick simulated stick. All the parts of the equivalent fuel assembly adopt stainless steel and are easy to process and produce; in comparison with the anti-vibration test using a real fuel assembly, the cost is greatly reduced and the safety of the test is high; in addition, the equivalent fuel assembly has quality characteristic, rigidity characteristic and modal characteristic close to those of the real fuel assembly and is suitable for the anti-vibration test of the fuel storage grillwork.
