Swinging vibro-exciter parasitic lateral oscillations lead to an increase of the amplitude of its vibration, which increases the inertial load on the transmitting platform, the vibration exciter and the sites of attachment to the platform. This reduces the durability of the vibration exciter and the vibro-exciter …
vibration exciter's LTS for precision calibration. The LTS which is made up of a base and a platform is connected to a (152 mm peak to peak) electro-dynamic exciter which is all mounted on an air bearing table which provides a rigid and stiff bearing surface. In conclusion the system biggest uncertainty contributor was defined. 1.
