The conclusion that one would like to make from a successful vibration test is that the component will endure a truck lifetime with a certain high probability. In reality truck components work under multiaxial loads meaning that the excitation is multiaxial. While the 3-Dimensional shakers are expensive to be used to simulate the real multiaxial vibrations, the testing equipment is normally a table that can be vibrated by Swept Sine Excitation or Stationary Random Vibration in merely one direction. Since the real vibration that a component is subjected to is a 3D-vibration, using uniaxial...
