Abstract: In the multi-point random excited vibration test with the same number of the load points and the response control points, the transfer relations among those points are analyzed. The genetic algorithm is adopted for the numerical simulation of the lower limit of the required control thrust for the two-point and three-point excitation modes. Since the phase differences among the multi-point response are usually not taken as a control target, the choice of the multi-point excitation is not unique, allowing for a more flexible handling of test condition. Meanwhile, it is necessary to optimize the thrust force loading distribution for making a sufficient use of the load equipment.
