Description
Technical field
The invention belongs to spacecraft structure technical field, relate to a kind of allowance test wire examination method being adapted to primacord fuse tripping device, be specifically related to the test method of mild detonating fuze tripping device comprehensive assessment separating property nargin and structure fatigue resistance nargin.
Background technology
Mild detonating fuze tripping device is using mild detonating fuze (MDF:MildDetonationFuse) as the separation energy; by detonation wave and high-temperature high-pressure fuel gas effect; cut off spacecraft structure covering; typical structure as shown in Figure 1; mainly comprise: separate housing 1 (radius is R), mild detonating fuze 2, protective cover 3 and securing member 4, being wherein separated thickness is d.Weakening groove 5 is generally the place that structural bearing intensity is the weakest, and when mild detonating fuze 2 acts on weakening groove 5, housing along weakening the fracture of groove 5 place, thus realizes the detachment process of structure.
The reliability of mild detonating fuze tripping device must based on the determination of Functional Margin.The determination of Functional Margin is in the past based on Go/no-Go test, and the unique data collected is effect or does not act on, but consequently Functional Margin may be excessive or too small, and number of trials is comparatively large, high cost.L.J.Bement points out that the Functional Margin of mild detonating fuze is examined by clapboard method, be placed on mild detonating fuze with the clapboard that cut material is made, put pressing plate more subsequently, the maximum depth of cut [1] of the rear clapboard of each ignition can be obtained, its Functional Margin is determined by changing medicine core explosive load, namely designs the ratio of the ratio of explosive load and minimum explosive load or minimum separation thickness and separate housing design thickness.
According to the classical theory of detonation physics amount, when the axis 7 of Fig. 1 mild detonating fuze overlaps with the axis 6 weakening groove, detonation wave utilization factor is the highest, is separated reliability and improves thereupon.By the axis 7 of mild detonating fuze and weaken groove axis 6 between distance definition be centering deviation x, due in actual production, assembling and operating process, be difficult to the centering deviation eliminating mild detonating fuze completely, so, the alignment degree x that tripping device allows is larger, and its Functional Margin is also larger, and visible alignment degree and separating property nargin are closely related, but it is not listed in the category of nargin examination by current research scholar.
At present, national military standard (GJB1307A-2004
[2]), American army mark (MIL-HDBK-83578
[3], AIAAS-113-2005
[4]) etc. the standard-required performance margin of the products such as priming device, explosion propagation device, cumulative blasting device and firer's acting device, and lack the specification of the nargin wire examination method of mild detonating fuze tripping device instructed.For cumulative blasting device, GJB1307A-2004 require that 67% small pit goaf cutting maximum gauge or design dose cut the performance margin of 1.5 times of maximum gauges, but do not carry out clearly to the examination of structure fatigue resistance nargin under large dose, because tripping device is while completing separation function, also should ensure the integrality of structure, prevent from detonation product or be separated fragment entering enclosure interior destruction interior instrument cable.And; for the weakening groove design of mild detonating fuze tripping device; multiple separation parameter will be changed while changing 1.5 times of maximum gauges; as the thickness etc. of crack arrest slot thickness, protective cover; whether this series of change finally can reflect that real 1.5 times of maximum gauge nargin are difficult of proof; therefore mild detonating fuze tripping device is not suitable for design dose and cuts 1.5 times of maximum gauges, and needs design one more reasonably structure fatigue resistance nargin wire examination method.
In the life cycle management of product, actually will experience various mechanics, nature and thermal environment condition.Conventional nargin certification test is only conceived to the determination of effect propety nargin, does not consider the combined influence by environmental baseline, and the nargin examination after experience various mechanics, nature and thermal environmental test, more will can reflect the nargin level of product reality.
