Kinetics analysis and response test of Horizontal Vibration centrifuge
Journal of China Coal Society, 2010Co-Authors: Cui Feng-luAbstract:Amplitude-frequency characteristics of Horizontal Vibration centrifuge was studied by establishing kinetics model of Horizontal Vibration centrifuge.Finite element simulation of the first ten steps of Vibration mode of Horizontal Vibration centrifuge was carried out.Vibration mode and steady response acceleration amplitude of sieve basket was obtained by experimental test.The results show that the fifth step of natural frequency of Horizontal Vibration centrifuge is 21.98 Hz which is 9.06% lower than Vibration frequency of Vibration motor.The first step of natural frequency of sieve basket is 20.57 Hz which is 14.89% lower than Vibration frequency of Vibration motor;steady response acceleration amplitude of no-load sieve basket is 56.2 m/s2.Steady response acceleration amplitude of sieve basket is 58.6 m/s2 when the mass of the processed material is 290 kg,whose Vibration absorption effect is 4.27% higher than that of no-load sieve basket.

Finite Element Simulation and Modal Analysis of Horizontal Vibration Centrifuge
Machine Design and Research, 2010Co-Authors: Cui Feng-luAbstract:Stress-strain distribution and Vibration mode of Horizontal Vibration centrifuge were received by establishing its finite element model and mechanical simulation. The result shows that: under the effect of the static force,integral displacement of exterior body and casing occurs,and the both sides of the casing have the bigger stress; The first-order,fifth-order and tenth-order natural frequency are 2. 058Hz,21. 98Hz and 74. 05Hz. When the fifth-order Vibration mode appears,Horizontal straight reciprocating motion of the whole vibrating body relative to the sieve basket will happen,and its natural frequency is 9. 06 percent lower than 24. 17Hz the working frequency of the vibrating motor. So,in order to improve the working performance of Horizontal Vibration centrifuge,the working frequency of the vibrating motor should be reduced,or the natural frequency of the vibrating body should be increased.

Research on Vibration Mode of Horizontal Vibration Dewatering Centrifuge
Machine Design and Research, 2010Co-Authors: Cui Feng-luAbstract:This paper investigates the Vibration mode of Horizontal Vibration dewatering centrifuge. All-order Vibration mode,Vibration shape and Vibration trajectory of casing,support body and sieve basket are studied. The result shows that:the ratio of the first-order natural frequency of base and support body and the rotation frequency of eccentric motor when centrifuge operates steadily is less than 0.54; The ratio of the first-order natural frequency of sieve basket and the rotation frequency of Vibration motor when centrifuge operates steadily is more than 0.85; The centrifuge spends longer time in going through the resonant region in the shutdown process; Exciting-Vibration force from the viberation motor canbe absorbed by the primary vibrating body of sieve basket etc.,during processing the matarials.

Kinetic Parameters Design and Vibration Response Test of Horizontal Vibration Dewatering Centrifuge
Machine Design and Research, 2010Co-Authors: Cui Feng-luAbstract:A kinetic model of Horizontal Vibration dewatering centrifuge was established. The stiffness and damping coefficient of rubber spring for isdating Vibration isolation,as well as the optimal equivalent mass of materials processed by dewatering centrifuge were ascertained. Vibration response test of the sieve basket and the spindle which are the main parts of dewatering centrifuge were carried out. Whether dewatering centrifuge is procesing the materials or not,the steady response frequency and the variation rule of acceleration amplitude for the sieve basket and the spindle were studied.

Horizontal Vibration suppression method suitable for super high speed elevators
Electrical Engineering in Japan, 1999Co-Authors: Nobuyoshi Mutoh, Kenkichi Kagomiya, Toshiaki Kurosawa, Masahiro Konya, Takeki AndohAbstract:Horizontal Vibrations of elevator cars mainly occur because a car swings as roller guides installed at corners of a car frame move on a winding guide rail at high speeds. Rider comfort in high-speed elevators is worsened by these Vibrations. Conventional active dampers suppressing Horizontal Vibrations using ac servomotors make cars heavier so driving power becomes larger, and they are not easily applied to existing elevators. An active damping control method suited to super-high-speed elevators is described which can solve these problems. The method suppresses Vibrations by generating only enough magnetic force needed to suppress them only when Vibrations of the car frame are produced. The Vibrations are detected using acceleration detectors and magnets installed on the left and right sides of the car frame. A computer simulator was made to analyze phenomena of car Vibrations and to verify effects of the proposed magnetic damping controller. It was found that the Vibrations generated on the cabin floor were remarkably large when the left and right sides at the upper and lower parts of the car frame were swung by sine waves with the same phase. The Vibrations had two resonant modes. Results obtained with the computer simulator and a full-scale running simulator showed that the acceleration on the cabin floor, even at the resonant frequencies, could be reduced by the magnetic damping control to around 0.1 m/s2 which would provide a comfortable ride. © 1999 Scripta Technica, Electr Eng Jpn, 129(1): 59–73, 1999
