Dynamic Characteristic Test And Modal Analysis Of VM1400Vibrating Centrifuge

In this paper, the experiments was done to study the dynamical properties of the VM1400horizontal vibrating centrifuge and the operating characteristics of the damping rubber spring, which was based on the mechanics, dynamics of machinery, the dynamic design theory of mechanic structure, mechanical electronics and the measuring method theory; and taken finite-element analysis and optimal design to the key components of the VM1400horizontal vibrating centrifuge by the ANSYS software. In the theory, establishing the dynamic model and the amplitude-frequency characteristic equation of the VM1400anti-vibration horizontal vibrating centrifuge, giving the measurement of vibration spring stiffness and vibration isolation spring stiffness, analysing the influencing factor of anti-resonance amplitude centrifuge screen basket, and providing the methods of improving the centrifuge job stability. It was obtained that the results of stress, strain, displacement calculation, and modal analysis which was based on the finite-element modeling, and reported the results of the top10bands of vibration modes according to the situation of1,2vibrating body static stress distribution, displacement, strain. In the experiment, test and data analysis ware taken to the static and dynamic characteristic, and the influence of the temperature on the dynamic stiffness of spring. It was obtained the first-order, second-order vibration natural frequency and formation of basket, prosthesis and cabinet through static tests and three different steady-state response through dynamic tests. It was studied the variation and factors of the response frequency and the acceleration amplitude from steady-state operation to parking static.
