Valve Spring Testing
IABG operates a self-developed resonance test bench for valve springs. It permits us to test a large number of valve springs at room temperature and at higher temperatures (up to 200 °C) with constant and variable loads and at high frequencies (up to 25 Hz). The test bench supports all types of valve springs and is limited only by the maximum permitted load (20 kN) and the length of the springs (max. 80 mm).
