"Vibration Comprehensive Experimental Teaching System" is specially designed for colleges and universities of higher learning in the mechanical discipline, civil engineering structures and mechanics. Combined with higher theoretical courses of institutions, this system may provide students with a complete vibration experimental lab equipment and methods to enable them to learn through visual experiments and to deepen their theoretical understanding. The system is an essential teaching experimental equipment. Configuration of the data acquisition instrument, amplifiers, and sensors can also be used for scientific research and experiment with optional software of signal acquisition, process and analysis.
