Problems solved by technology

However, before the engine test, it is necessary to debug the test bench to determine whether the performance of the test bench can meet the test requirements of the engine. However, there is no mature debugging method at present, which leads to the inability to grasp the overall performance of the test bench, thus Increased simulation time, increasing test costs

Embodiment Construction

[0056] A method for debugging state parameters of a test bench, wherein the type of debugging includes no-load debugging, on-load debugging, and hot-running, and the on-load debugging and hot-running include the following steps:

[0057] 1), debug the intake system;

[0058] 2), debug the heater;

[0059] 3) Debug thrust measuring equipment;

[0060] 4), debug ejector;

[0061] 5) Jointly debug the intake system, heater, thrust measuring equipment and ejector.

[0062] When debugging the intake system, the predictive control method is used to debug the intake state parameters of the test bench, which includes the following steps:

[0063] 1), according to the control amount of a single parameter obtained by the predictive control method, debug the intake pressure regulating valve;

[0064] 2) According to the control amount of a single parameter obtained by the predictive control method, debug the fuel proportional regulating valve of the heater

[0065] 3) According to t...

Abstract

The present invention discloses a debug method of state parameters of a test bed. The debug types comprises no-load debug, load debug and heat run. The load debug and heat run comprise the following steps: 1) debugging an air inlet system; 2) debugging a heater; 3) debugging a thrust measurement device; 4) debugging an injector; 5) performing a combined debug of the air inlet system, the heater, the thrust measurement device and the injector. Compared with the prior art, the debug method of state parameters of test bed provided by the invention is able to integrally grasp the performances of a test bed, reduce the test cost and improve the test efficiency.

Description

technical field [0001] The invention relates to a debugging method for state parameters of a test vehicle. Background technique [0002] At present, during the engine test, a set of parameters are required, including intake air total pressure, intake air flow rate, intake air oxygen composition, intake air total temperature, engine fuel supply, and air ambient pressure, which are called state points, and at the same time reach After setting the value and stabilizing, record its performance and parameters or assess its performance. However, before the engine test, it is necessary to debug the test bench to determine whether the performance of the test bench can meet the test requirements of the engine, but there is no mature debugging method at present, which leads to the inability to grasp the performance of the test bench as a whole Increased simulation time and increased test costs. Contents of the invention [0003] The object of the present invention is to provide a ...
