Development On Reconfigurable Digital Experimental Platform For Mechanical-electronic Measurement And Control

The Reconfigurable Manufacturing System (RMS) is designed for rapid change in structure, as well as in hardware and software components, in order to quickly adjust production capacity and functionality within a part family in response to sudden changes in market or in regulatory requirements. RMS, which combines the advantages of Dedicated manufacturing lines (DML) and Flexible manufacturing Systems (FMS), has become the key technology of improving the competitive capability in companies. As an advanced modern manufacturing philosophy, the reconfigurable theory is used in manufacturing field, information field and so on, displaying its specific superiorities. The modular method is the main technology to realize the reconfiguration of system's hardware. The development of reconfigurable products emphasizes the products' components and modular design, requires the reuse and recycle of all kind of resources that are existing during the period of design, in order to realize the rapid reconfiguration of the products.This thesis presents the basic theory of RMS and modular design, analyses the design course of applying modular design to the development of reconfigurable products. The development of reconfigurable hardware in products falls into three successive phases: architecture design, module design and development, and product assembly. The total design course of reconfigurable hardware in products consists of the above three phases. The thesis introduces the method applying reconfigurable theory to the development of experimental platform for mechanical-electronic measurement and control. According to the above course of modular design, using the Computer-aided Error Measurement and Control Device (EMCD) as the prototype, we completed the design of experimental platform's mechanical structure, developed a digital experimental platform for mechanical-electronic measurement and control based on the reconfigurable theory. The experimental platform is manufactured and the rationality of this product's modular design ideas is proved to be valid. The experimental platform can be rapidly reconfigurated in terms of the different requirement of each experiment item. The design of this product meets the anticipating demands.The thesis also presents the realizing courses of computer numerical control (CNC) dividing head experiment and planar cam profile dynamic measurement experiment, introduces the two experiments' principles and their reconfigurable processes of the mechanical structures, analyses the error which will affect the results of the measurement. Aimed to the two experiments, we developed their corresponding application programs.
