Dynamic modelling and response analysis of closed high-speed press system

Proceedings of the Institution of Mechanical Engineers Part K Journal of Multi-body Dynamics (2012)

Enlai Zheng Fang Jia Zhisheng Zhang Jinfei Shi

It is necessary to establish a dynamic model to predict and evaluate the dynamic performance of closed high-speed press system during design procedure, when it is impossible to carry out the test of prototype. In this work, a dynamic model for the closed high-speed press system is developed to predict and evaluate its dynamic performance. Unlike in previous models where the press frame is considered to be a single mass and the effects of the transmission mechanism and complex frame structure are neglected, the present model can be used to analyze the dynamic response of a multi-body vibration-impact system treating it as a coupled one. The simulation results reveal that the dynamic responses of press under piling condition include a transient impact and a free vibration process. The vibration acceleration and velocity curves of the upper beam of the closed high-speed press decrease with the increasing speed of rotation. In contrast, vibration acceleration and velocity curves of the lower beam of the press increase with the increasing rotation speed. The experimental results demonstrate that the dynamic model proposed herein is consistent with the actual working state of the closed high-speed press and the validity of the dynamic model is verified.

Mechanical properties of disc springs combined with PU

International Conference on Mechatronics and Machine Vision in Practice (2012)

Fang Jia Hongwei Sha Enlai Zheng Zhisheng Zhang

This study is focused on the mechanical properties of disc springs before and after adding polyurethane (PU) pieces. A static mechanical model of the disc springs combined with PU is established in this study by finite element method, which considers the effect of the friction between contact surfaces. Simulations and tests are carried out. The simulated static load-deformation characteristic curves match well with the experimental results, thus verifying the validity of the model. Simulation results reveal that PU piece has little influence on the static stiffness of disc springs. The dynamic load performance is also investigated through tests. Results from our experiments show that the PU piece is capable of lowering the dynamic stiffness of disc springs while keeping their static stiffness nearly constant. Our findings are supposed to provide theoretical basis for the reduction of the dynamic stiffness of disc springs as well as for the design of new combination isolators.

State-Feedback Stabilization for High-Order Output-Constrained Switched Nonlinear Systems

IEEE Transactions on Systems Man and Cybernetics Systems (2022)

Xiangze Lin Jinlin Xue Enlai Zheng Ju H. Park

For output-constrained switched systems, uniformly local stabilization problem via state feedback is addressed. A unified tool, a common tangent-type barrier Lyapunov function (Tan-BLF), is developed to deal with the stabilization problem of switched systems and to cope with constraints imposed on system output with or without. Then, combining adding a power integrator technique (APIT) and the developed common barrier Lyapunov function, state-feedback stabilizing laws are designed systematically to make the resultant closed-loop switched systems asymptotically stable while preventing the violation of output constraints. The efficiency of the proposed method is illustrated by numerical results.
