<p>The present invention relates to a method for test and a test system (2) and to the use of the system (2), which comprises a first and a second reciprocating movable load carriage (8, 10) connected by spring means (12). The object of the invention is to perform a vibration test at heavy components. This can be achieved if the reciprocating moveable load carriages (8, 10) are supported at a support platform (14), and the spring means (12) comprises a plurality of springs, which are supported by at last one support unit (14). Hereby can be achieved, that even a very heavy load can be placed on one of the reciprocating movable load carriages (8, 10) can be tested. The system (2) can operate most effectively if two equal masses can be tested at the same time. The frequency as such could be in the area from 1-10 hertz and the amplitude could be from 20-200 millimetres. In that way it should be possible for different loads to achieve acceleration in the area from 2-15 G.</p> |
