Its mechanism is as follows:

Before transmitting, it should be needed to carry out electronic fuse according to goal close fried to connect the electric time or touch fried set.

When transmitting, under recoil effect, after inertia sliding block compression sliding block spring moves down certain distance, clockwork is discharged Actuator, driving plate are become a full member in place under the control of clockwork by about 0.8s, meanwhile, centrifugal lock is in centrifugal acceleration Effect is outer to remove, and discharges the first turntable, releases the insurance to the first turntable；After driving plate rotate in place, safeguard is discharged, in torque Under effect, insurance board shaft is made to turn over certain safety angle, release activation firing pin rapidly；Activate firing pin in the case where activating spring effect of elastic resistance Stamp hits interior igniter cap of raming upwards, and the powder gases that igniter cap ignition generates push the percussive cap for raming and hitting and being loaded on battery bottom, Make battery activated；While activation firing pin stabs hit igniter cap upwards, the bar that will lock trigger mechanism discharges, and releases to quick-fried first First of insurance of turntable, at this point, sliding block contact pin is still stuck in the insurance hole of the first turntable under the action of recoil, first turn For disk still in flame proof position, electronic fuse is in safety position, and the battery after activation starts to power to timer, timer work Make, before the not up to timer set time, high and low frequency circuit does not work, and electronic fuse not will receive internal and extraneous Any interference, it is in a safe condition.

Powered phase is last, and when recoil suffered by sliding block is less than the remaining drag after sliding block spring overcomes other resistances, sliding block is in cunning It is moved up under the promotion of block spring drag, contact pin, which releases, insures the second of the first turntable, and the first turntable is become a full member in place, Explosive sequence To just, electronic fuse is in arm-to-arm, though electronic fuse arming at this time, connects what is not up to set in advance Before the electric time, high and low frequency circuit does not work still, and electronic fuse not will receive internal and extraneous interference still.

When reach set after connecing the electric time, supply voltage is added on the electronic building brick of electronic fuse by timer, high Frequency partially starts to space radiated electromagnetic wave, and the storage capacitor C of the firing circuit in low-frequency channel is started to charge, through 2s or so, Energy reserve on capacitor C is enough to ignite electric cap, and proximity action is partially in arm-to-arm.

When close to target, the electromagnetic wave that electronic fuse is radiate be reflected back after again by electronic fuse day Line is received, and Doppler signal is exported after detection, and low-frequency channel identifies signal frequency and amplitude, when bullet reaches in advance When determining height, firing circuit exports firing pulse, detonating primer, electronic fuse effect.

When electronic fuse closely fried disabler, when bullet hits target, contact switch closure or trigger mechanism are made With, electronic fuse effect can also be as needed, trigger action is directly selected, when bullet hits target, and trigger mechanism effect, Electronic fuse effect.

For the size of the first turntable 113, the compatibility design of 113 radius of revolving speed and the first turntable, root are considered According to centrifugal acceleration calculation formula A=0.0112Rn2, (A is constant acceleration unit g in formula, and R is that fuse installation calculates radial unit M, n fuse rotation speed unit r/min), by formula it is found that R and n are inversely when A is definite value.

R is bigger, and it is not easy to control to rotate stability, and takes up space and hand over greatly；R is smaller, and the revolving speed needed is higher, right Motor speed requires height, and the shear ability of corresponding installing component also requires height, comprehensively considers reliability and safety, using smaller part The mode of revolving speed is realized in diameter, when fuse installation radius is R=0.248m, n=330r/min, according to: A=0.0112Rn2, That is: A=0.0112Rn2=0.0112 × 0.248 × (330) 2=302.5, G=302.5/9.8=30.86g, i.e.,；Radio It is added on electronic fuse linear accelerating overload to fuse under this distance and speed conditions is 30.86g, meets and releases inertia and protect The required 30g acceleration in danger.It, will entire big first turntable, 113 radius in order to ensure the installation of electronic fuse and easy to process Be determined as R1=0.3m, mounting seat 111 at R=0.248m, in order to ensure rotation when equipment stabilization do not shake, with pedestal 111 diametrically designs etc. with the first turntables 113 pouring weight 6 are reconfigured, and install with pedestal 111 at axial symmetry.

The Design of Rotation of first motor 115 calculates

First is that power problem, it is to be ensured that the motor is able to drive the first turntable 113 and reaches egulation rotating speed；Power of motor needs 5.5kW specifically can choose motor model GRF01,7.5kW；

Second is that starting matter of time, it is to be ensured that the shorter the starting time the better, and the inertial acceleration simulated in this way is closer True value, by test of many times, accelerating the starting time is that 3s is most suitable, and is started 3s seconds as electronic fuse meter When device start the time, control device 5 start timing；

Third is that speed adjustability problem, considers that the apparatus function expands problem, in addition to being used to for emulation rocket projectile electronic fuse Property acceleration outside, it is also desirable to can emulate mortar projectile transmitting when inertial acceleration, therefore apply converter technique, pass through setting Frequency shift number of magnetic pole pairs, the revolving speed of effective raising and controllable motor.

According to formula:

N1=60s1 (1-s2)/p1 (1)

N=fn/p2 × n1 (2)

--- basic revolving speed p1 --- conventional motor magnetic pole in formula: n1

S2 --- basic parameter amount s1 --- supply frequency

Fn --- highest frequency n --- maximum speed

According to above formula, design is calculated and parameters obtained of tabling look-up is as follows:

P1=2 p2=28 (number of magnetic pole pairs after frequency conversion)

S2=0.1 (parameters obtained of tabling look-up)

S1=50Hz (mains frequency) fn=60Hz (design frequency)

(1) formula of substitution obtains

N1=60s (1-s)/p1=60 × 50 (1-0.1)/2=1350r/min

(2) formula of substitution obtains

N=fn*n1/p2=60*1350/28=2900 (r/min)

The maximum speed of the first turntable 113 as obtained by calculating above is 2900r/min, i.e., the first turntable 113 can be stepless Speed adjustable range is 0r/min~2900r/min, meets the requirement of 330r/min needed for testing, while also meeting mortar fuze 300g acceleration expands emulation demand.

In order to ensure the reliable arming of the electronic fuse, it is desirable that the centrifugal acceleration that its own revolving speed generates is at least 15g, in conjunction with 120 installation site of centrifugal acceleration emulation component, rotation speed is calculated as follows:

R=0.015m

N=1200r/min

According to: A=0.0112Rn²G=A/8

That is: A=0.0112R × 0.015=242

G=242/9.8=24.7g

That is: the CENTRIFUGAL ACCELERATING of electronic fuse is overloaded under this speed conditions because of the centrifugal slider distance in electronic fuse Centre distance be 0.015m its be added on electronic fuse CENTRIFUGAL ACCELERATING overload be 24.7g, be greater than its release centrifugation insurance plus Speed 24g meets and releases centrifugation requirement for insurance, so, 124 revolving speed of rotating electric machine of selection is in 1200r/min or more, electric rotating Machine 124 can choose DC speed-changing motor, and model can be SBD-CI08-W, and rotating electric machine 124 is as power with rotating basis 123 Electronic fuse is driven to do rotary motion, electronic fuse to be tested is mounted on the (inverse time on 123 Centric solenoid modal coil 1231 of rotating basis Needle rotation, electronic fuse the more turns the more tight on pedestal 123, avoids falling off when high speed rotation).
