Embodiment Construction

[0044] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] In order to realize the multi-degree-of-freedom thrust calibration of the six-component balance during the thrust calibration test, the present invention proposes a calibration device that can adjust the position of the force-measuring point. By performing static force loading on 6 positions of the balance, x Apply force and moment to the balance in the , y, and z directions. At the same time, the method of adding slide rails on the force-bearing surface of the balance is adopted to adjust the position of the force point on the balance to complete the force loading with variable positions in the horizontal and vertical directions, and to realize being controlled. Calibration of various forces and moments of measuring balances.

[0046] like figure 1 and figure 2 As shown, an adjustable six-component balance ca...

Abstract

The invention provides an adjustable six-component balance calibration device for an engine ground test, and solves the problems that an existing thrust calibration system only performs force calibration on a balance fixing point and cannot guarantee the loading accuracy and synchronism of multiple forces. The device comprises a base, a balance upper end electric cylinder force bearing seat, a first balance side edge electric cylinder force bearing seat, a second balance side edge electric cylinder force bearing seat, a force loading execution mechanism and a control system. The first balanceside edge electric cylinder force bearing seat is arranged on the base, and a first linear slide rail is arranged on the first balance side edge electric cylinder force bearing seat; the second balance side edge electric cylinder force bearing seat is arranged on the base; a third linear slide rail and a fourth linear slide rail are arranged on the balance upper end electric cylinder bearing seat;the force loading executing mechanism comprises a first electric cylinder arranged on the first linear sliding rail, and a second electric cylinder and a third electric cylinder which are arranged onthe second balance side edge electric cylinder force bearing seat, and comprises a fourth electric cylinder and a fifth electric cylinder which are arranged on the third linear sliding rail, and a sixth electric cylinder arranged on the fourth linear sliding rail; the control system controls the six electric cylinders to act.

Description

technical field [0001] The invention belongs to the field of ramjet free-jet tests, and relates to a six-component balance calibration device, in particular to an adjustable six-component balance calibration device for engine ground tests. Background technique [0002] In the field of ramjet free-jet testing, a six-component balance is usually required. During the development of the six-component balance, the designed balance needs to be calibrated to ensure the measurement accuracy of the balance. To this end, it is necessary to carry out the design of a six-component thrust calibration system. By loading multiple forces on the balance, the component force calibration of force and moment is realized. [0003] The existing thrust calibration system applies loads to the balance through multiple force loading actuators. Its disadvantage is that it can only perform force calibration on the fixed point of the balance, and the accuracy and synchronization of multiple component fo...
