Abstract: A measuring device according to the present invention is used for wind-tunnel testing of a vehicle having a plurality of wheels, and comprises a plurality of measurement modules in which the respective wheels are disposed, wherein: each measurement module comprises a housing having an opening in an upper portion, a load cell accommodated inside the housing, a movement mechanism for moving the load cell inside the housing, and a lid for blocking the opening in the housing; the lid is provided with a wheel-supporting member for supporting the wheel; the wheel-supporting member is configured to be capable of being disposed in any position in the lid; and the load cell is configured to measure a force acting on the wheel supporting member.

Abstract: A measuring device according to the present invention is for a vehicle arranged downstream of air blown from a blower for a wind tunnel test, the measuring device comprising: a measuring device main body configured to enable the arrangement of the vehicle and movement thereof relative to the blower; and a splitter connected to an end of the measuring device main body facing the blower side, wherein the splitter has: a main body portion having an upper surface continuous with the upper surface of the measuring device main body and a lower surface having a surface extending downward as the distance from the blower side increases; and a plate-shaped tip member extending from the tip of the main body portion toward the blower side, the upper surface of the tip member is formed to be continuous with the upper surface of the main body portion, an edge of the lower surface of the tip member on the blower side is positioned closer to the main body portion than an edge of the upper surface of the tip member on the blo

Abstract: A fluid machine including a rotating shaft that extends parallel to a power generation shaft of a power generation unit, and that has an end coupled to the power generation shaft; a multiple rotors that are provided on the rotating shaft so as to be able to rotate in a circumferential direction of the rotating shaft, and that are arranged so as to be spaced in a rotational axis direction parallel to the axis of the rotating shaft; and a differential mechanism that is provided between a pair of rotors lying adjacent to each other in the rotational axis direction, and that combines the rotational force from each of the pair of rotors and transmits the rotational force to the rotating shaft.
