The invention provides a fault diagnosis method for a reaction flywheel, and the method comprises the following steps: collecting the operation data of the reaction flywheel, and carrying out the preprocessing of the operation data; obtaining possible faults and fault occurrence probability of the reaction flywheel according to the preprocessed operation data; constructing a fault diagnosis path of the reaction flywheel; processing the fault diagnosis paths based on possible faults and fault occurrence probabilities by adopting a grey wolf optimization algorithm to obtain a sequence of the fault diagnosis paths; performing fault diagnosis based on the sorting result; according to the method, after fault diagnosis paths are formed through random composition of parts, used for fault diagnosis, of the reaction flywheel, the grey wolf optimization algorithm is adopted to compare and sort the fault diagnosis paths, and when fault diagnosis is conducted according to the sorting result, the fault diagnosis efficiency can be greatly improved, the fault position can be rapidly positioned, and the fault diagnosis efficiency is improved. Therefore, repair and maintenance can be carried out in time, and normal operation of the spacecraft is prevented from being affected.
