Description

A kind of measurement method of moonlet separating switch outreach
Technical field
The present invention relates to a kind of moonlet measurement methods of separating switch outreach, are particularly suitable for the moonlet satellite and the rocket The measurement of separating switch outreach in docking operation, belongs to spacecraft field of measuring technique.
Background technique
Moonlet is to provide the important devices of satellite satellite and the rocket separation signal with separating switch, is commonly installed and satellites coupling ring On.Separating switch is in impaction state under the unsegregated state of the satellite and the rocket, and separating switch is in release conditions after satellite and the rocket separation, According to the characteristic of separating switch, provide separation signal, at this time for Satellite when the 0s moment.Therefore the length of separating switch free end In the difference of impaction state and release conditions, i.e. separating switch decrement correctly provides separating switch separation signal and extremely closes Key may cause satellite launch powered phase and accidentally issue satellite and the rocket separation model in the process, to lead if separating switch decrement is insufficient On-board equipment work ahead is caused, priming system such as unlocks at the significant problems in advance;If separating switch decrement is excessive, separation may cause The problems such as switch bounce failure can not provide correct satellite and the rocket separation signal, and whole star can not start.
At present according to the product technology of separating switch manufacturer explanation, satellites coupling ring size and delivery adapter ruler Very little analyzed show that satellite-rocket docking in the process adjusts separating switch free end to how level can then make away from satellite-rocket docking face The decrement of separating switch after compaction is in rational state.Therefore separating switch is measured and adjusted certainly during satellite-rocket docking By holding the distance apart from satellite and the rocket interface to adjust separating switch decrement to zone of reasonableness, for correctly dividing after satellite launch Leave pass provide separation signal have great significance.
In the prior art, method of the separating switch free end at a distance from satellite-rocket docking face is measured during satellite-rocket docking is It is directly measured using vernier caliper depthometer, satellite-rocket docking face is withstood into as measurement in one end of the depthometer of vernier caliper Benchmark, slide calliper rule tail end withstand separating switch free end and measure.In the measurement process due directly to vernier caliper depthometer end Section is small, it is difficult to guarantee that slide calliper rule and satellite-rocket docking face are in plumbness, slide calliper rule are often in the state of skew, and separating switch is free End is often pushed back by slide calliper rule tail end, and measurement process slide calliper rule are in inversion state, may scratch satellite-rocket docking face due to maloperation. Therefore it is big difficulty, measurement error to be measured using slide calliper rule direct measuring method.
Summary of the invention
Technology of the invention solves the problems, such as: in order to overcome the deficiencies of the prior art, providing a kind of moonlet and is stretched with separating switch The measurement method of distance out, the distance by using measurement tooling and clearance gauge to satellite-rocket docking face relative to separating switch mounting surface The distance B3 of A3 and separating switch relative to separating switch mounting surface, to two surveys with separating switch mounting surface for same benchmark Examination amount, which is made the difference, obtains the distance between separating switch and satellite-rocket docking face C3, solves since slide calliper rule positioning datum is unstable It is fixed, in test process may accidentally pressure separating switch, easily scratch satellite-rocket docking face, so as to cause measurement it is difficult, measurement error is big The problem of.
