Static and Vibration test equipments

Quasi static test facilities

DTM since many years is managing testing activities of aerospace equipments for the most important Aerospace prime contractors: vibration testing, proof pressure tests, leak tests, quasi static tests, fatigue tests and many other specific verifications. In particular DTM has the capability to design and realize testing facilities for the most demanding applications.

For Rheinmetall Italia DTM designed and realized the testing jig and electronic which has been used by to qualify the VEGA interstage 2-3. The testing apparatus comprised hydraulic system capable of providing compression and flexural forces upto 100 ton and the Vega interstage was fully controlled by means of roughly one hundred between strain gages and position sensors.

For Thales Alenia Space DTM designed and realized the testing jig and electronic which has been used by to qualify and accept the Sentinel 1 Tank Support Structure qualification and flight models. Also in this case the TSS was fully controlled by means of strain gages and position sensors. DTM has been also in charge to demonstrate the correlation between expected structural analysis deformations and real displacements.

Vibration tests

DTM is able to manage all the qualification or acceptance process for vibration test of space hardware. This includes the preparation of the test procedures including all the definitions of the test parameters (sine, random, shocks), the execution of the tests, preparation of the test reports and correlation as required.

For this type of activities like for quasi-static tests DTM provides turn-key projects where the inputs are the requirements to be verified and DTM performs all the activities from the design and realization of the testing tool (if required), preparation of test-procedures up-to the delivery of all the test-reports. Depending on the mass and accelerations required the test is performed with DTM shaker or a shaker located at outside laboratory in Italy.

In the frame of the testing activities related to vibration tests we also design and realize containers for vibration test, fixtures and all hardware required for a successful execution of the test meeting all project requirements in terms for instance of dynamic response and maximum accelerations allowed on the hardware.

Tests are performed either with DTM vibration shaker (c/o Università di Modena) or external facilities.
