Abstract

The invention belongs to the technical field of sensing and measurement control, and provides a six-dimensional dynamic force generating device. A vibration exciter is changed to serve as an arrangement form of modal experiment excitation, so that the requirement for six-dimensional dynamic force simulation loading of a micro-vibration test platform is met, and the overall calibration experiment effect is improved. The device is composed of bases, the vibration exciter, stand columns, an upper beam, guides, a connecting rod, standard force sensors, a main direction connecting plate, a side direction connecting plate and a loading plate. The device is reasonable in structural design, simple to operate and reliable in work; and the application range of excitation of the vibration exciter isgreatly expanded.
