TRAVELLING CARRIAGE FOR SUPPORTING MODEL

摘要

PROBLEM TO BE SOLVED: To provide a control unit to enable tests as a towing wind tunnel in order to eliminate changes in the apparent weight of a travelling carriage for supporting a model for supporting and moving the model due to aerodynamic load exerted on the model or the model and the carriage and changes in the location of control points of the carriage and the attitude of the model, in the travelling carriage which requires both the adoption of an elastic vibration isolating support device of an extremely flexible structure at wheel supporting parts and a structure for preventing vibrations from rails or travelling surfaces from transmitting to the carriage and the model. SOLUTION: Wing-shaped lift suppressing devices 6 are mounted to the travelling carriage for supporting the model. By controlling the angles of attack of the wings to generate corresponding load in order to cancel static load which occurs in the model 40 or the model 40 and the carriage 1 while travelling, missing of the control points of the carriage and changes in the attitude of the model are prevented. An active system or a passive system is used for the elastic vibration isolating support device.
