Testing device and method for simulating ultra-high-speed penetration ground impact effect

The invention discloses a test device and method for simulating an ultra-high-speed penetration ground impact effect, and the device employs a static load loading system to apply a static load to the periphery of a sample so as to simulate a ground stress environment, and employs a dynamic load loading system to apply an impact dynamic load to the top of the sample so as to simulate ground impact. In the dynamic loading system, a phase change reaction kettle is used for heating liquid CO2 to a supercritical high-pressure state; the liquid filling module is used for filling liquid CO2 into the phase change reaction kettle; the gun barrel is used for receiving high-pressure gas released by the phase change reaction kettle and forming ground shock waves similar to a plane; the stress wave lens module is used for adjusting the width of shock waves through a stress wave lens combination and acting the shock waves on the sample; the control module can control the shock wave peak pressure by regulating the heating power of the phase change reaction kettle, and can control the duration time of shock waves by regulating the bore diameter of the gun barrel. According to the invention, controllable and high-fidelity simulation of the ultra-high-speed penetration impact effect is realized.

A variable-stage, variable-capacity water tank

This invention relates to a variable-order, variable-capacity water tank. The technical problem this invention aims to solve is to provide a nonlinear, multi-purpose water tank with variable order and variable capacity. The technical solution adopted by this invention includes a water tank body, a sealing plate, a first insert plate, a second insert plate, and a third insert plate. The water tank body includes a bottom plate and a tank casing. The tank casing is divided into a first inlet chamber, a first outlet chamber, an overflow chamber, a second outlet chamber, a second inlet chamber, a first working chamber, a second working chamber, and a third working chamber by a water tank partition. Water passage holes are provided between the first inlet chamber and the first working chamber, and between the second inlet chamber and the third working chamber. The advantages of this invention are: the water tank structure is ingeniously designed, allowing for variable capacity and variable order, enabling the construction of mathematical models of various orders; the structure of the sealing plate and insert plates replaces the traditional manual valve structure, exhibiting more significant nonlinear characteristics, enabling the system to stabilize quickly, shortening experimental time, and increasing the controllable range.
