Virtual Prototyping Technology

According to the traditional design method, in order to manufacture a mechatronic system, from the initial idea, the designer designs the mechanical system by CAD (Computer-Aided-Design), this system is then fabricated, finally, the system will be tested on the working condition. If the system does not work properly, the design of the system will be changed, and hardware is re-manufactured. This method is more time-consuming and cost for repairing and manufacturing hardware repeatedly. To save design time and reduce the cost of the manufacturing hardware as well as to optimize the design process of a mechatronics system, this paper introduces an engineering model it is called a virtual prototyping technology which allows optimizing the designs on the computer before manufacturing the test-bed system. Based on the concept of the system working, the mechatronics system is designed on SOLIDWORKS and then exported to the ADAMS software (Automated Dynamic Analysis of Mechanical System). The flexible element is also modeling and analysis in ANSYS software then exported to ADAMS. The integrated simulation in ADAMS environment is executed to investigate the dynamic behaviors of the mechanical system and design will be adjusted. Virtual prototyping model will then be exported to MATLAB/Simulink to develop the control strategies. Co-simulation results in some contexts to evaluate the effectiveness of the proposed mechatronic system before implementing on test-bed

The optimal design of vacuum switch is becoming an important research topic with the extensive application and increasing demands of vacuum switches. This paper analyzes the main elements of the vacuum switch design, and gives the design process of the vacuum switch. An optimal design method is proposed for the vacuum switch based on the concept and characteristics of virtual prototyping (VP) technology. By using computer aided design and the related software, we propose a method for vacuum switch modeling VP, the stress field VP of parts, the thermal field VP of electric heat, the electric field VP of insulation parts and the mechanical dynamic VP of kinematics system, which are integrated for optimization design for vacuum switches. This work is expected to provide a new idea for optimal and rapid design of vacuum switches.

Optimization And Simulation

Mechanical design have experienced a long process of development, the improvement of design method and optimization method have always been the pursuit of any designer. In recent years, introduction of CAD/CAE have increased greatly the speed of design and experiment, making mechanical design undergo a fundamental leap. However, the whole process: design-trial-improve- ment, still needs manual control to complete, designers still face the problem of complex repeating process. In views of this bottleneck, we will conduct parametric modeling on complex mechanical system in PRO/E, and let key parts import into ANSYS to be flexible .Then, we will build and analyze rigid-flexible mixture virtual prototyping in automatic dynamic analysis of mechanical systems. At last, we will integrate this process in ISIGHT3.5, exploring design-trial-improvement integrated optimization and simulation method through the optimization of the size of key parts of complex mechanical system.

Stabilizing Controllers

SUMMARYAn underactuated mechanical system is generally a good test bed for advanced nonlinear controllers and can be applied to design a novel mechanical system with better energy efficiency and good controllability. It has been shown that the dynamics of many underactuated mechanical systems could be transformed into the chained canonical form. To improve the performance of the controllers presented in the literature, a novel controller design method is proposed in this paper. It is shown that the set-point stabilization problem of the second-order chained form systems can be changed into a trajectory-tracking problem based on the nonsmooth Hölder continuous feedback. By designing the tracked trajectory, the presented controller permits the achievement of exponential stability. Some numerical simulations demonstrate the stability of the proposed controller for an underactuated Hovercraft system.

In this paper we propose an Hardware-In-the-Loop (HIL) system for industrial drives. The system allows the user to optimize the design of control strategies by emulating complex mechanical applications. In fact, with this approach it is possible to simulate the behavior of the real mechanical system, and therefore to verify a priori the effectiveness of a control strategy and to achieve a rapid prototyping of the mechatronic system. The structure of the system consists of a couple of brushless motor which are connected by a mechanical joint. In one drive the control functions related to a specific application are implemented while the other one is used to replicate the mechanical system model of the application. A modular approach has been selected in order to allow a rapid development of a given application. In particular, a library of components has been implemented both in Simulink and in an IEC61131-3 language.

Expert systems, or knowledge based systems, are programs in which the answer to a user-posed question is reached by logical or plausible inference rather than strictly by calculation, although calculation routines can form a major part of an expert system. Based on the integration of expert system technology and optimization technology, an intelligent computer aided design method for mine ventilation systems is proposed in this paper. Firstly, the structure and control algorithm of the intelligent design system are explored. Secondly, the knowledge types required for the mine ventilation expert system and the acquiring method of knowledge are discussed. Finally, the inference method of this expert system is put forward.
