The invention provides an operation vibration mode determination method and apparatus, and an electronic device. The method comprises the steps of obtaining a modal vibration mode and a modal frequency of a to-be-detected device; according to the modal frequency, selecting a target modal shape of the to-be-detected equipment from the modal shapes; according to the target modal shape, determining a weighted interpolation coefficient matrix between a to-be-detected point and a vibration detection point on the to-be-detected equipment; according to the weighted interpolation coefficient matrix, the vibration value of the to-be-detected point is determined, and the operation vibration mode of the to-be-detected equipment is determined through the vibration value, so that the operation vibration mode of the to-be-detected equipment can be obtained by arranging a small number of vibration detection points, and meanwhile, the accuracy of obtaining the operation vibration mode of the to-be-detected equipment is impro
