Embodiment
Be described in detail below in conjunction with Fig. 1, Fig. 2 and the utility model of Fig. 3.
Step 1: the first function module circuit plate 1, the second function module circuit plate 2 are fixed on the fixed head 11.Fixedly the time, according to the first function module circuit plate 1, the vibration resistance of the components and parts of the second function module circuit plate 2, impact property, the element that quality is big is installed near the first function module circuit plate 1 or the second function module circuit plate 2, and the high direction of element rigidity and the master of the external drive direction of shaking is overlapped, can improve element vibration strength on the plate greatly like this, install when producing, for the bigger element of quality (each pin static load is greater than 7 grams), or the big (element of 1mm＞a＞25mm) of the bigger element (width/length＞1/4) of lateral dimension and solder pad space length a, all adopt LTV silicon gel sets element, to improve natural frequency and vibration strength; The local embedding of the components and parts of indivedual resistance to shock differences and the programmable chip socket that needs to rewrite are adopted the very strong round pin receptacle of contact engaging and separating force, to guarantee its contact reliably.
Step 2: the first function module circuit plate 1 and the second function module circuit plate 2 are reinforced, the first function module circuit plate 1, the second function module circuit plate, 2 each functional module and structural member have vibration characteristics separately, and functional module and structural member assembling present the 3rd vibration characteristics in meeting together.Produce in order to prevent above-mentioned phenomenon, do following two kinds of vibration isolation, impact mitigation measure by the frequency multiplication law: one is that a fixed head 11 is fixed on second fixed head 5, another piece fixedly fixed head 11 is in parallel, increase metallic stud 6, metallic stud 7 are connected and fixed on 1 first function module circuit plate 1 and the second function module circuit plate, 2 energy module and first fixed heads 4 of diverse location fixed head 1, to strengthen the rigidity between the first function module circuit plate 1 and the second function module circuit plate 2; The 2nd, accept between first fixed head 4, second fixed head 5 with support column 3, make bracket assembly as a whole, increase whole bracket assembly intensity.
Step 3: at first fixed head 4, second fixed head is set up vibration isolator 10 for 5 four jiaos, with screw assemblies 8 metallic stud 6 or metallic stud 7 are fixed on first fixed head 4 or second fixed head 5, in analyzing and calculate by the finite element software ABAQUS to vibration source, screw assemblies 9 passes fixing hole 14 on vibration isolator 10 side plates 13 with side plate 13 and first fixed head 4, second fixed head 5 is fixing, adopt eight vibration isolators 10 can be the first function module circuit plate 1 and the second function module circuit plate, 2 effective vibration isolation and vibration dampings, the fixing hole 14 on vibration isolator 10 base plates 12 is used for stationary electronic devices functional module vibration damping equipment.
By this conceptual design air environment passed through the examination of every s function vibration 1 hour, durable vibration 7.5 hours and shock test smoothly, and the examination by reliability test, any destruction does not appear in off-test equipment, the equipment operation is normal.Equally, equipment is installed in the helicopter, does not find the electronic devices and components poor contact of contacts, and indicator light work is undesired, and crackle appears in the moulding components and parts, soldering and melting welding place disconnection etc. phenomenon, the requirement of satisfying the air environment vibration fully and impacting.
Technique scheme has embodied the optimal technical scheme of utility model technical scheme, and the local variation of scheme still belongs within the utility model protection range.
