The action process is as follows:

before launching, the radio fuse is required to be subjected to near blasting power connection time or blasting and setting according to the requirement of a shooting target.

During launching, under the action of recoil force, the inertia sliding block compresses the sliding block spring to move downwards for a certain distance, a driving piece of the clock mechanism is released, the driving plate is rotated to be in place through about 0.8s under the control of the clock mechanism, and meanwhile, the centrifugal pin is withdrawn outwards under the action of centrifugal acceleration to release the first rotating disc and release the safety of the first rotating disc; after the driving plate rotates in place, the safety plate is released, and under the action of torque, the shaft of the safety plate rapidly rotates by a certain safety angle to release and activate the striker; the activation firing pin upwards pokes a fire cap in the firing head under the action of the resistance of the activation spring, and gunpowder gas generated by firing of the fire cap pushes the firing head to strike the striking cap arranged at the bottom of the battery so as to activate the battery; when the fire cap is stricken upwards at the activation firing pin, release the pin of locking trigger mechanism, remove the first insurance of exploding first carousel, at this moment, the slider contact pin still blocks in the insurance hole of first carousel under the effect of recoil, first carousel still is in the flame proof position, the radio fuze is in the insurance state, battery after the activation begins to supply power for the timer, the timer work, before not reaching timer dress fixed time, high, the low frequency circuit is out of work, the radio fuze can not receive inside and external any interference, be in the safety condition.

At the end of the active section, when the recoil force borne by the sliding block is smaller than the residual resistance force of the sliding block spring after overcoming other resistance forces, the sliding block moves upwards under the pushing of the resistance force of the sliding block spring, the contact pin removes the second insurance of the first rotating disc, the first rotating disc rotates to the right position, the booster sequence is aligned, the radio fuze is in a state to be issued, at the moment, although the insurance of the radio fuze is removed, the high-frequency circuit and the low-frequency circuit still do not work before the preset power connection time is not reached, and the radio fuze still cannot be interfered by the inside and the outside.

When the set power connection time is reached, the timer applies power supply voltage to the electronic component of the radio fuse, the high-frequency part starts to radiate electromagnetic waves to the space, the energy storage capacitor C of the ignition circuit in the low-frequency circuit starts to be charged, the stored energy on the capacitor C is enough to ignite the electric detonator after about 2s, and the explosive action part is in a standby state.

When the target is approached, the electromagnetic wave radiated by the radio fuze is reflected by the target and then received by the radio fuze antenna, a Doppler signal is output after detection, the low-frequency circuit identifies the frequency and the amplitude of the signal, and when the shot reaches a preset height, the ignition circuit outputs an ignition pulse to ignite a detonator, so that the radio fuze has the function.

When the radio fuze is in failure of the near-explosion function, when the shot impacts the target, the impact switch is closed or the triggering mechanism acts, the radio fuze acts, and the triggering action can be directly selected according to the requirement, and when the shot impacts the target, the triggering mechanism acts and the radio fuze acts.

For the size of the first rotary disk 113, considering the matching design of the rotation speed and the radius of the first rotary disk 113, according to the centrifugal acceleration calculation formula a ═ 0.0112Rn2 (where a is a constant acceleration unit g, R is a fuse mounting calculation radius unit m, and n is a fuse rotation speed unit R/mi n), it can be seen that when a is a constant value, R and n are in inverse proportion.

The larger R is, the stability is not easy to control in rotation, occupied space is increased, the smaller R is, the higher the required rotating speed is, the rotating speed of the motor is high, the shearing capacity of the corresponding mounting part is also high, the comprehensive consideration on reliability and safety is realized by adopting a mode of rotating at a small radius and a medium rotating speed, when the mounting radius of the fuse is R0.248 m, n 330R/min, according to the conditions that A is 0.0112Rn2, namely A is 0.0112Rn2 is 0.0112 × 0.248 × (330)2 is 302.5, G is 302.5/9.8 and 30.86G, namely, the linear acceleration overload of the radio fuse on the radio fuse is 30.86G under the conditions of the distance and the rotating speed, the 30G required for releasing the inertia safety is met, in order to ensure the mounting and the convenience for processing of the radio fuse, the whole large rotating disk 113 is determined as R1, R is 0.3, the first rotating disk 113 is designed to be not symmetrical with the first rotating disk 111, and the rotating disk is not required for being symmetrical with the first rotating base 111, and the same as the rotating disk is designed for ensuring the diameter of the first rotating base 111.

Designed calculation of the rotational speed of the first motor 115

One is power issue, which is to ensure that the motor can drive the first rotating disk 113 to reach a specified rotating speed; the motor power needs 5.5kW, and the motor model GRF01 and 7.5kW can be selected specifically;

secondly, the starting time problem is that the shorter the starting time is, the better the starting time is, the more the simulated inertial acceleration is close to the true value, after a plurality of tests, the accelerated starting time is 3s which is most suitable, the 3s second of the accelerated starting time is used as the starting time of the radio fuse timer, and the control device 5 starts to time;

thirdly, the speed is adjustable, the function expansion problem of the device is considered, the inertial acceleration of the rocket projectile radio fuse is simulated, and the inertial acceleration of the mortar projectile during launching is expected to be simulated, so that the frequency conversion technology is applied, the number of pole pairs is changed by setting the frequency, and the rotating speed of the motor is effectively improved and controlled.

According to the formula:

n1＝60s1(1-s2)/p1 (1)

n＝fn/p2×n1 (2)

in the formula: n1 basic speed p1 conventional motor magnetic pole

s2 basic reference number s1 supply frequency

fn-maximum frequency n-maximum rotational speed

According to the above formula, the parameters obtained by design calculation and table lookup are as follows:

p1 ═ 2 p2 ═ 28 (logarithm of pole after frequency conversion)

s2 ═ 0.1 (parameters found by table lookup)

s 1-50 Hz (mains frequency) fn-60 Hz (design frequency)

Substituting into formula (1) to obtain

n1＝60s(1-s)/p1＝60×50(1-0.1)/2＝1350r/min

Substituting into formula (2) to obtain

n＝fn*n1/p2＝60*1350/28＝2900(r/min)

R＝0.015m

n＝1200r/min

according to the following steps: a is 0.0112Rn²G＝A/8

That is, A is 0.0112R × 0.015 is 242

G＝242/9.8＝24.7g

Namely: under the condition of the rotating speed, the centrifugal acceleration overload on the radio fuse is 24.7g which is larger than the centrifugal insurance relief acceleration 24g because the centrifugal slide block in the radio fuse is 0.015m away from the center, so that the centrifugal acceleration overload on the radio fuse meets the requirement of relieving the centrifugal insurance, the rotating speed of the selected rotating motor 124 is more than 1200r/min, the rotating motor 124 can be a direct current variable speed motor with the model of SBD-CI08-W, the rotating base 123 is used as power for the rotating motor 124 to drive the radio fuse to rotate, and the radio fuse to be tested 123is arranged on the central screw pipe 1 of the rotating base 123 (anticlockwise rotation, the tighter the radio fuse rotates on the base 123, and the radio fuse is prevented from falling off during high-speed rotation).
