Modification of a test bench for testing torsional stiffness
Languages of publication
Described modification concern a test bench for testing torsional stiffness. The bench was created to analyze behaviour a middle part of a new type of an active stabilizer. The middle part was was replaced by two or four profiles with rectangular cross-section which are constantly connected with not-changed parts of stabilizer (with its arms). Specially designed mechanism is responsible for changing stiffness and it performs it so that the profiles are expanded in the middle of sample on the same distance in opposite direction. An article contains brief description of mentioned test bench and one of a few issues which were revealed during investigations – weak accurancy of obtained results. It was determinated that modification in the area of the bench drive and change in recording system should allow on increase accuracy. After modifications became able to observe a phenomenon of changing torque behaviour, from linear to nonlinear, during twisting expanded sample.
