Test parameter, test condition and the test method of energy component;Finally according to rudder system internal structure, critical function module testing knot
Fruit, which obtains, repairs Parameters of The Parts, realizes that the rudder system depth of unknown structure is repaired.The rudder system examination method of repairing of the present invention helps to dash forward
The broken external technology blockage to China, contributes to research and grasp of the China to blocking technology.
Embodiment
It is described in further detail below with reference to rudder system examination repair method of the preferred embodiment to the present invention.
The rudder system examination method of repairing of present pre-ferred embodiments comprises the following steps:
1) rudder system spare part is decomposed one by one, is numbered one by one, and draws rudder system structural drawings and part drawing, with
This determines rudder system internal structure.
When disassembling rudder system, first subregion decomposes, then decomposes each area one by one, such as rudder system is divided into top, lower part, left part
With four portions of right part, first rudder system is untied by four parts, then decomposes four portions one by one;Such as run into when subregion and each area of decomposition
Functional unit (such as functional unit, the critical function component with housing entire package) does not first decompose the functional unit, first by the work(
Energy component is regarded as entirety, determines the functional unit and other functional units and structure, the position relationship of part;Press function group in each area
After part, part decompose, then decompose each functional unit.That is decomposable process is progressively decomposed that (hierarchical structure is really by certain hierarchical structure
It is fixed not limit, as long as can accomplish in order), numbered when decomposing, side rendering architecture drawing, i.e., numbering can be by hierarchical structure
Carry out, by hierarchical structure rendering architecture drawing.
Detail drawing must be drawn for rapid wear, easily consumption part.
Rudder system internal structure is can determine that by progressively decomposing rudder system.
2) the technical data analysis of random import, rudder system principle analysis, the collection statistics of original performance parameter, property are passed through
The methods of practical proof of energy bound of parameter scope, determines the one integral piece performance test parameter of the important control function component of rudder system, and
Determine the test condition and test method of one integral piece performance test parameter.The important control function component includes servo valve and distribution
Device.
The important parameter test method of servo valve:Mainly drawn on servo valve test experimental bed by high precision flow
The no-load characteristic of the output quantities such as servo valve output flow, interior leakage quantity and input signal (the corresponding different amplitude of each parameter, frequency)
Curve.
