    摘要： A method for optimising a cycle and optionally high-cycle fatigue test rig, said test being intended to reproduce a support for turbomachine parts, wherein it comprises the steps consisting of determining variable geometric parameters of the support member and/or of the workpiece of the rig, in addition to ranges of variation of these parameters, determining at least one aim to be achieved, a variation in the values of at least a part of the abovementioned parameters having an influence on this aim, modifying one or a plurality of the values of the abovementioned parameters, in the respective ranges of same, and determining those that make it possible to achieve the aim, and producing or modifying a support member and/or a workpiece on the basis of the optimised parameters.
