[0025] Figure 2 The present invention is a flow chart of the test method of the dynamic response test device of the in-line fuze. DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1 As shown, this embodiment provides a dynamic response test device for an in-line fuze, including a boost circuit, a high-voltage initiation circuit, a voltage comparator circuit, and a programmable module; the boost circuit is electrically connected to the high-voltage initiation circuit and the voltage comparator circuit at the same time; the programmable module is electrically connected to the high-voltage initiation circuit and the voltage comparator circuit at the same time; the high-voltage initiation circuit is electrically connected to the voltage comparator circuit.

[0028] In this embodiment, an energy component is also included. The energy component is electrically connected to the boost circuit, the voltage comparator circuit, and the programmable module to provide working power for them. The energy component can use a rechargeable lithium battery pack to buffer and protect the lithium battery to ensure that it can provide power even under overload conditions.

[0029] In this embodiment, the programmable module has a built-in energy storage capacitor, an overload sensor and a ferroelectric memory which are electrically connected to each other.

[0030] In this embodiment, power supply, digital supply, and analog supply are provided by connecting different battery packs of energy components before the test. After the wiring is completed, the device is placed in a small artillery test bomb for firing.

[0031] like Figure 2 As shown, this embodiment also provides a test method for a dynamic response test device of an in-line fuze, comprising the following steps:

[0032] a. The energy component provides working energy to the boost circuit, voltage comparator circuit, and programmable module. The energy component provides working energy through different battery packs, and the battery packs are isolated and independent from each other.

[0033] b. The high-voltage detonation circuit transmits signals to the programmable module through the voltage comparator circuit, and the signal is a voltage-divided signal. After receiving the voltage-divided signal from the high-voltage detonation circuit, the voltage comparator circuit compares it with the preset comparison voltage and outputs a high or low voltage-divided signal. Specifically, the + end of the voltage comparator is a fixed voltage, which is compared with the voltage provided to the - end by the high-voltage detonation module. If the voltage at the + end is greater than that at the - end, a high level is output, otherwise a low level is output.

[0034] c. The programmable module transmits signals with the boost circuit through the voltage comparator circuit, and the signal is an excitation signal of a special frequency. The excitation signal of a special frequency transmitted by the programmable module is a square wave signal with a fixed frequency and a fixed duty cycle.

[0035] d. The boost circuit transmits high voltage to the high voltage detonation circuit. The wires transmitting high voltage should be high voltage resistant wires and well insulated.

[0036] e. The programmable module transmits signals to the high-voltage detonation circuit, and the signals are trigger signals. There are also signals directly transmitted between the programmable module and the high-voltage detonation circuit, including power supply positive and power supply ground.

[0037] f. Achieve overload equivalence through different targets. Specifically, replace different targets and evaluate the working conditions of the test device under different overloads. The target can be determined by overload simulation and other means.

[0038] The present invention uses only the necessary modules of the in-line fuze and only uses a single path, and at the same time greatly simplifies the release process of the in-line fuze, and greatly reduces the cost and cycle of the dynamic response test of the in-line fuze.

[0039] The present invention designs a dynamic response test device and test method based on a small-caliber artillery test projectile. When the dynamic response capability of the circuit design, buffer design, etc. of the in-line fuze needs to be verified or optimized, the in-line fuze dynamic response test device of this scheme is used to conduct a firing test according to the test method. The programmable module in the dynamic response test device records the parameters and dynamic overloads that need to be assessed during the test. After the test, the programmable module is recovered to read back the assessment parameters and overload information during the test. By analyzing the data, it is determined whether the in-line fuze design meets the assessment requirements. After the assessment is successful, the dynamic response assessment of the in-line fuze is further conducted. The small-caliber artillery test projectile has a short production cycle, a simple test process, a low test product cost, and a low test fee. Compared with other assessment methods, it has great time and cost advantages.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
