A mechanical shock tester is a device used to simulate and measure the impact of sudden mechanical shocks on products, verifying their ability to withstand such forces without damage.

Core Functions

Shock Simulation: Reproduces real-world shock scenarios, such as drops, collisions, or transportation vibrations, in a controlled environment.
Performance Testing: Evaluates whether products (e.g., electronics, automotive parts) maintain functionality and structural integrity after shock exposure.
Data Acquisition: Records key parameters like shock acceleration, duration, and direction to quantify the impact intensity and product response.

Common Types

Different testers are designed for specific shock modes, with the main categories listed below:

Type	Working Principle	Typical Application Scenarios
Drop Tester	Lifts the product to a set height and drops it freely onto a specified surface (e.g., steel, concrete).	Testing small consumer electronics (phones, tablets), packaging, and small mechanical parts.
Pendulum Tester	Uses a pendulum to strike the product with a fixed force and speed, simulating lateral or frontal impacts.	Evaluating the impact resistance of automotive components (bumpers, glass) and industrial equipment casings.
Shaker Tester	Drives a platform via an electromagnetic or hydraulic system to generate short, high-acceleration shock pulses.	Testing precision instruments (sensors, aerospace components) and large equipment (servers, industrial controllers).

Key Technical Parameters

These parameters determine the tester’s capabilities and suitability for specific tests:

Shock Acceleration: The maximum acceleration the tester can generate, usually measured in g-force (g) (1g ≈ 9.8 m/s²).
Shock Duration: The length of time the shock pulse lasts, typically ranging from 0.1 ms–100 ms; shorter durations correspond to more intense, instantaneous impacts.
Shock Pulse Shape: The waveform of the shock, with the most common types being
half-sine wave (simulating soft impacts),
square wave (simulating rigid collisions), and
sawtooth wave (simulating sudden stops).

Typical Application Industries

Electronics: Testing smartphones, laptops, and circuit boards to ensure they survive drops or transportation shocks.
Automotive: Verifying the durability of airbags, sensors, and engine parts under collision or vibration conditions.
Aerospace: Validating the resistance of avionics and satellite components to launch or landing shocks.
Packaging: Assessing whether packaging materials (cartons, foam) can protect products during shipping and handling.
