Description

Technical Field

[0001] The present application relates to the technical field of wind tunnel aerodynamic testing, and specifically to a loading device for a non-resetting fully automatic half-mold balance calibration system. The present invention can be installed once on the non-resetting fully automatic half-mold balance calibration system to achieve calibration of all components and directions of the half-mold balance, and is particularly suitable for a high-speed wind tunnel fully automatic half-mold calibration system. Background Art

[0002] The non-reset fully automatic half-mold balance calibration system can realize the loading of the half-mold balance in four directions, namely, positive Y, negative Y, positive Z, and negative Z. With one installation, the individual or combined loading of each component of the half-mold balance can be realized, thereby completing the calibration of the half-mold balance. During the calibration of the half-mold balance, the half-mold loading device is both a force-applying device and a force-transmitting device. The force load (torque load is also realized by applying different forces to the loading point) is applied to the loading point of the half-mold loading device, and is transmitted to the half-mold balance connected thereto through the half-mold loading device, thereby realizing the calibration of the half-mold balance.

[0003] The current half-mold calibration system (automatic or non-automatic) is built at an early time, and considering the construction cost and space requirements, it generally has no loading capacity in the positive Y direction (some half-mold calibration systems have loading capacity in the Y direction, but only to balance the weight of the loading head); therefore, in one installation, only loading in three directions, positive Y or negative Y and positive Z, negative Z, can be achieved. To achieve loading in four directions, two installations must be performed, and the work efficiency is low. The existing half-mold loading device mainly adapts to this mode.

[0004] The characteristics of the half-mold balance are large load-bearing capacity and poor matching of longitudinal and transverse loads. In the non-reset fully automatic half-mold balance calibration system, longitudinal and transverse calibration can be achieved simultaneously; under the action of a large longitudinal load, the position of the transverse loading point changes greatly due to the deformation of the loading head; vice versa, the longitudinal and transverse cross interference increases.

[0005] The arrangement of loading points in four directions, namely positive Y and negative Y, positive Z and negative Z, on the loading device of the non-reset fully automatic semi-module balance calibration system is the key to ensuring the point and direction of force application. If the arrangement is improper, when the load is applied, the position of the force application point will change greatly, introducing additional interference, thereby reducing the uncertainty of the balance calibration.

[0006] Therefore, a new device and / or method is urgently needed to solve the above problems. Summary of the invention

[0007] The invention object of the present application is to provide a loading device for a non-resetting full-automatic semi-mode balance calibration system. By adopting the present application, once installed on the non-resetting full-automatic semi-mode balance calibration system, individual or combined loading in various components and directions of the semi-mode balance can be achieved to complete the calibration work. By adopting the present application, the working efficiency can be improved, the cross interference of the longitudinal and transverse component loads can be reduced, the space of the main frame can be saved, and the accurate positioning of the force direction and action point can be ensured, the additional interference caused by the offset of the force action point and direction can be reduced, and the uncertainty of the semi-mode balance calibration can be improved.
