Mechanical Testing is a very specialized field where ALTER Technology is a high qualified laboratory. You can comply with customer qualification requirements with a mechanical test, improve your product reliability, estimate life expectancy, and perform package testing.
Within mechanical Testing, ALTER Technology laboratory has developed a new capability to perform constant acceleration tests.
The main goal of these tests is to apply a fixed value acceleration to verify that the equipment will operate properly during exposure to acceleration stress, such as would be experienced in aircraft, missiles, etc. This type of test can be carried out with an electromechanical exciter or with a centrifuge (depending on the mass of the equipment and the value of the acceleration to be applied).
The centrifuge generates acceleration loads by rotation around a fixed axis. The direction of acceleration is always radially toward the center of rotation, whereas the load induced by acceleration is always radially away from the axis of rotation. When mounted directly on the test arm, the equipment under test experiences both rotational and translational motion.
The acceleration and load-induced direction are constant with respect to the equipment under test for a given rotational speed, rotating 360 degrees for each revolution of the arm. The acceleration and induced load are in direct proportion to the distance from the center of rotation.
To carry out operative tests, a battery system is used to supply the equipment under test. This system is installed inside the centrifuge, allowing it to work both in parallel and in series. The connection with the equipment is made via Wi-Fi.
Due to this new development, tests can be performed in compliance with:
