Vibration Testing

DynaQual provides controlled vibration testing to cover the vibration frequency spectrum, from 5 Hz to 2,500 Hz, including low range frequencies not covered by HALT/HASS testing between 5 Hz and 800 Hz. In qualifying new electronic and mechanical systems through the HALT/HASS process, the products undergo testing by applying both thermal and random vibration to identify weaknesses in the design before they are finalized for commercial production. “Random” vibration in a HALT chamber covers a broad band, between 5-5000Hz and can also obtain measurements up to 10,000 Hz. The HALT process does NOT focus its energy in the low frequency range (1-800Hz). Shaker systems complement HALT/HASS testing but provide very different vibration profiles.These systems produce controlled inputs to the test article in various modes to excite the product in defined axes, over specific frequency spectrums and at set acceleration values.
