KRD11 is a fully automatic pneumatic lifting vertical shock test system. It is vertical shock test equipment with novel design, high degree of automation, simple operation and convenient maintenance. It is used to measure and determine the impact resistance of products or packaging, and assess the functional reliability and structural integrity of the test product in a shock environment. KRD11 series pneumatic shock test system meets the requirements of both shock and bump test, shock testing waveform including conventional half-sine wave, post-peak sawtooth wave, trapezoid wave, to realize the shock wave and shock energy that the product is subjected to in the actual environment, thereby improving the system or optimizing the structure of the product. This equipment meets the requirements of MIL-STD-202, MIL-STD-750, MIL-STD-810, MIL-STD-883, IEC68-2-27 and other standards.

Pneumatic Shock Tester Table
KRD11 series pneumatic vertical shock test system is composed of three parts: a table body, a pneumatic control system, acceleration sensor, and an electrical control measurement system. The schematic diagram of pneumatic vertical shock test system is shown as bellow.
The test sample is installed on the worktable, which is guided by two high-precision sliding guides and can move up and down. The two cylinders are connected to the worktable by sliding guides. When the cylinders are inflated, the piston rod rises to drive the worktable to lift. The workbench is lifted. When it is raised to the set height, the cylinder quickly deflates, and the bottom surface of the worktable hits the waveform generator to complete a shock process. It can be seen from the above shock process that by adjusting the rising height of the worktable, different initial shock speeds can be obtained, and thus different shock overload values can be obtained; while changing the stiffness of the waveform generator, different pulse width values can be obtained. With the coordination and cooperation, various shock test waveforms that meet the design index requirements can be obtained. By adjusting the input air pressure, the shock frequency can be controlled to meet the test requirements.
Dual Mass Shock amplifier
The shock amplifier is a device that uses the rebound energy of the ordinary impact shock table to realize the opposite impact between the servo table and the seat on the amplifier, so that the impact acceleration is multiplied.
KRD11 series pneumatic vertical shock test system is equipped with a half sine wave generator. The half-sine wave generator is mainly made of engineering rubber (considering the stiffness and cohesive force of rubber) and felt pads of various thicknesses. Different thicknesses are connected in series to form multiple stiffnesses to achieve different shock pulse widths. Optional for post-peak sawtooth wave generator which is lead cone; trapezoidal wave generator air source is high-pressure nitrogen, the pressure range is 1-10MPa, and the over
