Mechanical shock test machine

Mechanical Shock Test System and Equipment China Supplier

Mechanical Shock Tester is used to simulate the shock wave and shock energy that components, finished products or packaging may suffer during use and transportation, to determine the shock resistance of products, such as functional reliability and structural integrity in shock environments, and to assess the protective ability of the packaging. It is widely used in aerospace, shipbuilding, military, automotive, consumer electronics and other industries.

Our shock test machines are capable of performing shock tests of half-sine, sawtooth, trapezoidal and other waveforms. The specimen is mounted to the working platform and can be elevated to a specified height under the guidance of vertical precision guide bars. The desired peak acceleration and pulse duration are achieved with the cooperation of the waveform generator at the bottom of the base after the shock occurs. Waveform generators of different specifications can be easily replaced by manual.

The mechanical shock test equipment is installed with professional shock testing software in English. All parameter settings and test controls are realized through a built-in computer and a touch screen on the face of the control cabin. The operation is simple and convenient and supports manual lifting and lowering of the shock head assembly. After the setting is completed and the test is started, the mechanical shock tester can automatically complete multiple impacts. All real-time parameters and waveforms are displayed on the computer screen. The measurement system has a robust sampling rate of up to 1 MHz, which has the ability to capture the shock waveform accurately and quickly. All test data can be stored, recalled, printed, etc.

Let’s take the shock test in Chapter 38.3 in the United Nations Dangerous Goods Transport Manual as an example. This test item requires a shock test machine to assess the robustness of cells and batteries against cumulative shocks. Each cell and battery(battery depending on the mass) shall be subjected to a half-sine shock of peak acceleration of 150 g and pulse duration of 6 milliseconds. Alternatively, large cells or large batteries(batteries depending on the mass) may be subjected to a half-sine shock of peak acceleration of 50 g and pulse duration of 11 milliseconds. Each cell or battery is required to suffer three shocks in the positive direction and three shocks in the negative direction in each of three mutually vertical mounting positions for a total of 18 shocks.

Mechanical Shock Test Machine Structure Description

AMADE TECH shock test system comprises a specimen mounting platform, lifting system, braking system, buffering system, waveform generator, acceleration sensor, measurement system, control system, etc.

  • The platform is made of high-strength aluminium alloy, allowing various sizes to accommodate your samples. It comes with a pair of long screws, nuts and an I-shaped crossbar to secure the sample.

  • The lifting gear runs with the help of the ball screw driven by the motor to raise the sample platform to a preset height. The lifting height of the mechanical Shock Tester is measured by the photoelectric encoder assembly installed on the base. The photoelectric encoder measurement has the characteristics of high precision, strong anti-interference ability and high reliability.

  • The braking system adopts pneumatic braking and a strong friction braking, which can effectively prevent secondary impact braking and prevent secondary rebound.

  • The cushioning system at the bottom of the seat effectively reduces the impact force on the ground during the impact test. We specially designed a set of self-buffering systems consisting of a base, damper and airbag.

  • Waveform generators are divided into different types according to different waveforms. Among them, the half-sine wave generator is mainly made of engineering rubber, or wool felt. A variety of different thicknesses are connected in series to form a variety of stiffnesses to achieve different impact pulse widths.

  • The measurement system supports a maximum sampling rate of up to 1MHz, a maximum test acceleration of 100,000 gn, and a minimum test pulse width of 0.1ms. You no longer have to worry about missing even the slightest shock event. It’s also an integrated solution, so you don’t have to be busy viewing and recording waveforms. It can do everything from capturing shock events to generating reports. What’s more, it also provides you with the Shock Response Spectrum (SRS) analysis function, which can help you effectively evaluate the potential damage of the shock pulse to the actual system. Finally, ancillary force-deformation, shock response, etc., can help you understand more details about shock results.
