Sound can not ignore, and otherwise will influence the normal work of rail control engine, cause missile miss.Therefore a kind of appearance is needed
Precise tracking control valve performance test methods, can improve the design of valve and provide foundation, or master-plan is carried
For amendment data.
The content of the invention
In view of this, the present invention is directed to present in existing solid rail control rocket engine engineer applied test system not

Control system 2 is installed on testing stand body 1, and high pressure cold is transported at gas control valve by cold air transfer pipeline 3, by cold
Gas control system 2 controls the switch of burnt gas valve, and number is gathered via the pressure sensor on rail control motor power testing stand
According to, and it is transported to acquisition system.
As shown in figure 3, cold air transfer pipeline 3 is arranged on gas control valve upper end from top to bottom.In the middle of gas control valve
Aperture is steam vent 8, and left and right ends are jet pipe, and controlling organization uses pendulum mechanism, and a left side for pendulum is controlled by low and high level
It is right to swing, to control the break-make of air-flow.
The method of testing of the perturbed force of cold air transfer pipeline 3 and the perturbed force of steam vent 8 is illustrated with reference to Fig. 4 Fig. 5.
Assume first that the perturbed force of cold air transfer pipeline 3 is constant, be designated as Fc；The perturbed force of steam vent 8 thinks constant, is designated as Fe；
Force value obtained by sensor is designated as Ft.It can then be obtained according to force analysis：
Fc+Fe=Ft (1)
As shown in figure 4, disturbing cold air transfer pipeline 3 force value and the interference of steam vent 8 force value to test, step is such as
Under：
(1) larynx is sprayed in left side to be blocked with plug with right side spray larynx.
(2) cold air is passed through, now the Ft that makes a concerted effort of the perturbed force of steam vent and cooling pipelines is obtained by gathering sensing data
.
(3) larynx is sprayed in left side and right side spray larynx turns 180 degree, and blocked with plug.
(4) cold air is passed through, now steam vent force value is constant, direction changes, cooling pipelines force value and direction do not change, its
It can be obtained with joint efforts by gathering sensing data.
(5) by data processing, it is cooler pipeline perturbed force that the summation of making a concerted effort of test measurement twice, which is divided equally,.
(6) the cooler pipeline perturbed force that step (5) is tried to achieve, which brings formula 1 into, can try to achieve steam vent perturbed force.
As shown in figure 5, carrying out force analysis to valve leak force value Fv, it can obtain
Fc+Fe+Fv=Ft (2)
Based on above-mentioned analysis, valve leak force value tests are carried out, step is as follows：
(1) left side spray larynx is blocked with plug, right side spray larynx keeps unimpeded.
(2) be passed through cold air, steam vent perturbed force, the perturbed force of cooling pipelines and valve leak power make a concerted effort Ft can be by adopting
Collect sensing data to obtain.Because steam vent has been obtained with refrigerator pipe force value, measured value now is subtracted and asked
