Schwingungserreger mit Lastkompensation |
摘要 |
A vibration exciter with load compensation for the dynamic excitation of test specimens includes a base, an actuator, an armature which can be moved by the actuator in an excitation direction relative to the base and guided by a linear guiding element parallel to the excitation direction, and a pneumatic load compensator which compensates for the gravity force of at least the armature and the test specimen being excited. A high-quality low-perturbation exciter signal is generated by minimizing friction and other nonlinearities occurring during the load compensation. The linear guiding element of the vibration exciter with load compensation includes an air bearing, and the load compensator includes the linear guiding element. |
