Abstract

A 2-DOF dynamics model of vibration isolation in vibratory piling is built up. Based above, the optimization model of parameters of vibration isolation is derived. Then, the parameters of vibration isolation are solved by complex method. Finally, the optimal result is compared with that by experience.

Abstract

Two methods is proposed to modify the shape of combined subdivision surface. One is to realize the shape modification of the combined subdivision surface by editing the curve network and updating the surface by the overlapping subdivision method, and the other one combines vertex constraint with the shape optimization method based on discrete PDE(partial differential equation), and realizes the shape modification of inner surface far away from the interpolating curves. The two methods effect on combined subdivision surface's different areas during shape modification. They can complement each other to realize the shape modification of the combined subdivision successfully.

14. The Multiobjective Optimization of Mechatronical System of Single Manipulator Based on Pareto GA.

Author

ZHU Deng-lin, WANG An-lin, WANG Shi-gang, and ZHUANG Han

Abstract

The integrated structure/control modeling of single-manipulator and concurrent optimal methodology for multiobjective were studied. According to the requirement of dynamical and control stability performance, the optimal model with multiobjective and constraints was proposed by combination of the dynamics of flexible structure and poles configuration, and solved by Pareto GA (PGA). In the process of PGA optimization, the technique of regularization of objectives, graded penalized function technique to remove constraints, Pareto-rank of population and Pareto set filter are used. To protect the feature and multiformity of Pareto set, a clustering analysis technique is used to limit the number of individual in Pareto set. [ABSTRACT FROM AUTHOR]

15. Integrative Design of Machine and Controller: Flexible Beam and Controller Syncretic Design.

Author

Abstract

Primary to solve the problem of model coupling between shape of structure and parameters of control system, this thesis focuses on the flexible arm with single-input & single-output as an example. Take the moment of inertia, inherent frequency and control energy as aim to optimize the structure of flexible arm, position of force and parameters of controller, to improve the performance of system. Give the method of design complicate mechanical and control system, reduce the dimension of controller using mode theory, and the model coupling design were proposed. Comparing with the traditional method of design mechanical and controller, it is proved that the integrated performance of the system can be improved. The method of synergetic design of mechanical and controller was proposed, which can be used to resolve the coupling between the parameter of mechanical and parameter of controller.
