Abstract: A compressor includes a casing that is horizontally elongated or vertically elongated, an electric motor housed in the casing, a compression mechanism driven by the electric motor to compress a refrigerant, a plurality of supporting portions arranged between an inner peripheral surface of the casing and an outer surface of the electric motor, and a reduction mechanism provided in the casing. The plurality of supporting portions support the electric motor in the casing. A plurality of predetermined spaces are formed between the inner surface of the casing and the outer surface of the electric motor. The plurality of predetermined spaces are separated by the supporting portions. The reduction mechanism reduces a resonant mode that is excited in the plurality of predetermined spaces by operation of the electric motor.

Abstract: A predicting method includes a first step and a second step. The first step includes outputting initial information indicating states of a structure and an object when the object is assembled to the structure, by simulating a process of assembling the object to the structure. The second step includes outputting first prediction information indicating future states of the structure and the object by simulating temporal change of assembly state in which the object is assembled to the structure, using the initial information.
