Combined Temperature and Vibration Testing

Combined Temperature and Vibration Testing

Combined environment testing effectively evaluates failure modes induced exclusively under mutually interacting environments such as under the combination of vibration and temperature simultaneously, in testing labs. It is an essential type of testing that helps understand the stresses induced on materials due to vibrations under low or high-temperature or at a varying rate of temperature conditions. While vibration testing can give valuable information, combined testing with temperature can closely replicate actual operating conditions, especially when the materials’ intended end-use exposes them to both environments. Testing routinely involves employing hydraulic vibration systems with capabilities to run the test within large thermal chambers, specialized vibration-temperature testing chambers like HALT/HASS, dual thermal chambers to simulate different thermal conditions, varying rates of temperature changes, and thermal shock tests on specimens under vibration. Thermal shock testing is also done to evaluate end use of thermal properties of materials and products.

The product’s durability is examined under both the influence of each stress alone and in combination. This will make any manufacturing or design flaws quickly apparent.

Combined temperature testing, combined vibration testing, and combined environment testing plays a crucial role in industries like aerospace, heavy machinery, automotive, electronic devices, packaging to help avoid catastrophic damage to materials and equipment. Customized testing methods are developed by experienced technicians, at Infinita Labs laboratory network in the USA, based on the product or specimen’s requirements and standards.
