A novel high-strength large vibrating screen with duplex statically indeterminate mesh beam structure

Journal of Vibroengineering (2017)

Zhenqian Wang Chusheng Liu Jida Wu Haishen Jiang Bao-cheng Song

Screening is an indispensable unit process for separation of materials. Large vibrating screen is extensively used in coal processing because of its large production capacity. In this study, a novel large vibrating screen with duplex statically indeterminate mesh beam structure (VSDSIMBS) was presented. The dynamic model of VSDSIMBS was proposed, and characteristic parameters were obtained by theoretical calculations. In order to obtain more reliable and believable research results, model of a traditional vibrating screen (TVS) with the same mass was also established for comparisons with VSDSIMBS. The finite element (FE) method was applied to study the performance of VSDSIMBS and FE analysis of VSDSIMBS and TVS was completed by using characteristic parameters. Modal analysis results indicated that VSDSIMBS could avoid the resonance and run more smoothly than TVS. Furthermore, harmonic response analysis results showed that VSDSIMBS could improve the entire stress distribution, reduce high stress areas, and increase the strength of vibrating screen. With DSIMBS, the maximum stress of vibrating screen decreased from 130.53 to 64.54 MPa. The full-scale experimental tests were performed to validate the credibility and accuracy of FE analysis results. The stress and displacements of VSDSIMBS were measured under working conditions. The test results obtained are in good agreement with simulation results, and accord with conclusions made from FE analysis.

Research on Screening Mechanism of Cascade Screen

Mining & Processing Equipment (2000)

Chusheng Liu

On basis of the theory that elastic surface screens moist fine material, this paper studies the dynamic characteristics of cascade screen surface and derives the design formula of grates. It also finds out why the cascade screen can deal the material difficult to be treated-and that the screen surface has a large elastic vibration amplitude and high rate of aperture.

Vibration analysis of a rectangular-hollow-sectional beam with an external crack

Journal of Vibration and Control (2016)

Liping Peng Chusheng Liu

The vibration property of a rectangular-hollow-sectional beam with an external crack were theoretically and experimentally studied in this paper. The external part-through crack and through-thickness crack were considered. Linear elastic fracture mechanics were employed to establish the theoretical formula for computing the equivalent torsion spring stiffness of the two external cracks. Then, the experimental method of obtaining the equivalent torsion spring stiffness was developed. It is seen that the test data match fairly well with the analytical data. On this basis, the transfer matrix method was introduced to obtain the frequency equations of these cracked beams under three classic boundary conditions, and followed by the numerical method for calculating natural frequencies. Experimental tests on clamped–free beams were used to verify the accuracy. It should be noted that a part-through crack may lead to a more distinct natural frequency reduction than the through-thickness crack.

Virtual Experiments and Talent Cultivation

Journal of Huaihai Inscitute of Technology (2003)

Chusheng Liu

Virtual instrument system is the production of combining computer technology with measurement and control technology. The application of virtual instrument to teaching has reformed the teaching method of experimental teaching and has improved the effect of experimental teaching. Discussions are made in this paper on the reforming of experimental teaching by applying virtual instrument technology, and the role that virtual experiment plays in the cultivation of talents. With the yearly expansion of enrolling scale in colleges and universities, the number of students increases rapidly, and the instruments and facilities of experimental teaching can no longer meet the requirements of educational development, thus making the experimental teaching run adrift with the actual engineering technology. The adoption of virtual instrument experiment, nevertheless, can remedy the deficiency of experimental teaching based on traditional instruments and satisfy the demand in college educational reform and the cultivation of talents.

Lightweight design of a crane frame under stress and stiffness constraints using super-element technique

Advances in Mechanical Engineering (2017)

Ang Li Chusheng Liu

Crane frame is one of the core components of the crane. Important performance indexes for the design of a frame include stiffness, manufacturability, and durability. Simultaneously, lightweight of the frame is also critical for decreasing the consumption of manufacturing and transportation. Crane is a complicated multibody structure, and therefore, using the traditional method to analyze will consume large amounts of computing time, and the accuracy cannot be expected. In order to solve these problems, a novel and effective method, super-element global modal parameterization, is employed in this article. The advantages of using this approach are that the complex models can be reduced, while the important effects are still taken into account. The design procedure consists of three steps: first, the finite element model is used to analyze the original frame. Then, the stiffness and von Mises stress obtained from the analysis are treated as the design constraints in the next topology and thickness optimization. Finally, a validation of the optimum design for durability is performed, and the results show that all the performances satisfy the requirements. The frame structure has a 15.12% reduction in total mass, while the performance is improved compared to the original.
