Mechanical impact tests
Ensuring the strength and reliability of your equipment
Why carry out mechanical impact tests?
- Validate the resistance of products to anticipated or accidental shocks in real conditions of use or transport.
- Identify potential mechanical weaknesses before the product is put on the market.
- Comply with standards and technical specifications specific to each sector of activity.
- Optimise product life and reliability by simulating severe impact environments.
Shock tests, the current typology of shocks
Our laboratories are equipped to carry out various types of tests:
- Half-sine shocks: Simulate sudden impacts with an acceleration rise and fall in the shape of a half-sine.
- Sawtooth shocks: Reproduce shocks with a rapid ascent and a more gradual descent.
- Trapezoidal shocks: Constant acceleration over an extended period.
- Shock Response Spectrum (SRC): Analyses the reaction of the product to a range of shock frequencies.
- Simulation of pyrotechnic shocks and shock response spectra.
- Accelerometric measurements on equipment can be carried out.
- Possibility of producing "à la carte" shocks with different durations and amplitudes
Potential failure modes identified during testing
- Mechanical deformation.
- Poor electrical contacts.
- Appearance of micro-cracks.
- Breakage of assembly structures.
- Modification of electrical characteristics.
- Component soldering problems.
