The vibration exciter is composed of two side plate vibration motors connected by a universal coupling. The screen box is supported by 8 springs. The screen box has an inertial vibrating screen with approximate circular motion track, which is also called a single axis vibrating screen.
The force transducer is used along with the exciter to measure the input force applied to the SUT. In vibration testing, the SUT is attached to the exciter table through a test fixture.2 In this case, the SUT is driven by base excitation signals that are transmitted to the SUT through the test fixture.
