[0028] In the present application, the near-blast electronic detonation module 13 is installed on the trolley 3 to simulate the projectile, and the trolley 3 slides on the steel cable 4 to simulate the terminal trajectory; the installation angle of the near-blast electronic detonation module 13 is adjusted to simulate different attack angles of the projectile, and different ground effect objects are arranged on the ground according to the test requirements, and the data acquisition equipment is arranged, so that different tests can be simulated and corresponding data can be acquired.

[0029] Considering that it is difficult to reach the speed required by the terminal trajectory only by gravity sliding of the trolley 3, and if the steel cable 4 is lengthened and the test tower 12 is increased, the cost will be greatly increased, therefore, the spring cable 5 is arranged on the ground below the steel cable 4.

[0031] The elastic rope 5 in the scheme is in a stretched state during the entire movement process of the trolley 3; see Figure 1 , the lower end fixed point of the elastic rope 5 (i.e. the connection position of the elastic rope 5 and the tension measuring system 7 through the rope connecting hook) is A on the corresponding position of the steel cable 4, A is the intersection of the vertical line passing through the lower end fixed point of the elastic rope 5 and the steel cable 4; then during the sliding process of the trolley 3 from the starting point above the steel cable 4 to A, the force of the elastic rope 5 on the trolley 3 will always generate a component along the steel cable 4 downward, and this component together with the component of the gravity of the trolley 3 along the steel cable 4 downward drives the trolley 3 to accelerate, thereby enabling the trolley 3 to reach the required speed at the end of the steel cable 4; by selecting elastic ropes 5 with different elastic coefficients or preforming different elastic stretching amounts, the size of the component of the force of the elastic rope 5 on the trolley 3 along the steel cable 4 downward can be adjusted, thereby adjusting the speed of the trolley 3 on the steel cable 4; and when the trolley 3 passes A on the steel cable 4, the force of the elastic rope 5 on the trolley 3 will always generate a component along the steel cable 4 upward, which is used as a damping force of the trolley 3 to intercept the trolley 3.

[0032] In order to better realize lossless recovery, the scheme is provided with a blocking cable mechanism; see the attached Figure 1 The blocking cable mechanism includes an intercepting rope 8, the intercepting rope 8 is arranged on one side of the ground fixed point 11 at the lower end of the steel cable 4, is located above the steel cable 4 and is perpendicular to the steel cable 4, and is about 2 m away from the ground height; the two ends of the intercepting rope 8 are respectively provided with a damper 9 and a fixed steel plate, and the fixed steel plates are respectively fixed on the second cement base 10.

[0033] When the trolley 3 contacts the intercepting rope 8, the trolley 3 continuously slows down and finally stops moving under the action of the damper 9, at which time the recovery of the near-blast electronic detonation module 13 can be carried out.

[0034] See the attached Figure 2 The trolley 3 includes a middle connecting plate 16, the upper surface of the middle connecting plate 16 is provided with two groups of pulleys 15, and the steel cable 4 passes through each group of pulleys 15 to install the trolley 3 on the steel cable 4; the lower surface of the middle connecting plate 16 is provided with an adapter plate 14, the adapter plate 14 is provided with an adjusting groove and a bolt hole, and the near-blast electronic detonation module 13 is matched with different bolt holes and adjusting grooves to adjust the installation angle.

[0035] Referring to the drawings Figure 1 and Figure 2 In order to facilitate the reset and test of the trolley 3, the scheme is provided with a winch 1 at the top of the test tower 12, a trailer 2 connected with the winch 1 is arranged on the steel cable 4, and the trailer 2 is connected with the trolley 3 through a release mechanism; the trolley 3 is driven to reset by the winch 1 to facilitate the next test; the release mechanism can be an electronic buckle or the like.

[0036] On the basis of the above technical scheme, the application further provides a test method of the low-speed near-blast electronic detonation module 13, and the steps are as follows:

[0037] Step 1: Before the test, the installation angle of the steel cable 4 is designed and the tension value of the elastic rope 5 is calculated according to the test technical requirements, so that the speed of the trolley 3 can meet the test requirements when the trolley 3 slides to the action height of the near-blast electronic detonation module 13 on the steel cable 4; in this example, the steel cable 4 is inclined at an angle of 45° (measured by the end of the steel cable 4).

[0038] Step 2: The corresponding ground effect is set according to the ground environment required by the test of the near-blast electronic detonation module 13.

[0039] For example, if the effect of the near-blast electronic detonation module 13 on ordinary farmland is to be examined, the soil used for farmland can be covered on the ground; if the effect of the near-blast electronic detonation module 13 on sandy land is to be examined, sand and stone can be laid on the ground; if the effect on water surface is to be examined, a corresponding water pool can be made on the ground, and so on.

[0040] Step 3: The near-blast electronic detonation module 13 is installed on the trolley 3 and the installation angle is adjusted to simulate the required attack angle according to the test requirements, then the elastic rope 5 is connected with the trolley 3, and the trolley 3 is driven to the initial position above the steel cable 4 by the winch 1 and the trailer 2.

[0041] Step 4: After the data acquisition equipment is arranged on the ground, the test is started; the data acquisition equipment can be a signal acquisition instrument, an optical-electric conversion device, a speedometer, a high-speed camera, and the like.

[0042] The release mechanism is controlled to be opened, and the trolley 3 accelerates to slide along the steel cable 4 under the double actions of its own gravity and the elastic rope 5; when the trolley 3 reaches the action height of the near-blast electronic detonation module 13, the near-blast electronic detonation module 13 generates an action signal and outputs the signal to the signal acquisition instrument or the optical-electric conversion device; when the trolley 3 reaches the end of the steel cable 4, the trolley 3 contacts with the blocking cable mechanism and slows down to 0 m / s, thereby completing one test.
