Study on the Multi-domain Modeling and Optimization Designing Method for the Band Sawing Equipment

Abstract

This paper is oriented to the design and analysis process of the high-level band sawing equipment, and studied the modeling and the simulated optimization design method for the high-level band sawing equipment based on the unified modeling language. The unified constraint model is used to describe the multi-domain model of the CNC band sawing equipment. The model libraries for the mechanical structure, the hydraulic pressure and the control of the CNC band sawing equipment are established to complete the unified multi-domain constraint model for the simulation optimization. Aiming at the multi-domain, multi-objective, multi-constraint and multi-variable characteristics for the model of the high- level band sawing equipment, we studied the planning solution, the optimization strategy and the analysis methods for the multidisciplinary design optimization based on the multi- domain model. The unified simulation platform for the multi- field of the corresponding cutting equipment is developed to provide the research foundation and the technical support for optimizing and improving the accuracy and efficiency of the band sawing equipment. The band sawing equipment is a complex system of the mechanical-electric-hydraulic-control, and its design is a very difficult and complex task. While the present various engineering applications gradually improve the performance of the band saw equipment, the design of the band saw system is becoming increasingly complex and difficult. When the band saw equipment is developed today in China, the empirical design method is widely used. It is reliable in quality, but it is difficult for product innovation and technological innovation. The much material consumption, more complex structure, high cost and difficulty in the application of new technologies are increasingly unable to adapt to the applications of the modern engineering technology in the band saw equipment. How to successfully apply new technologies and to implement new design concepts for improving the technical level of the band saw equipment and developing the high-level band saw equipment becomes a major issue need to be solved. The multidisciplinary design optimization (MDO) is just the new design method of the complex system proposed to achieve better the new design concept. Its main idea is to fully utilize the distributed computer network technology to integrate the various disciplines of knowledge in the entire design process of the complex systems. In accordance with the design- oriented thinking, the various disciplines of models and analytical tools are integrated. Through the effective design, the optimization of the strategy, and the management of the design process, the coordination interaction between the various disciplines is fully used to obtain the optimal solution of the overall system. On the foundation of the multidisciplinary design optimization method, the analytical tools are used to build the efficient design and analysis platform for the band saw equipment. So that can get the optimal design of the overall system. The design platform is of great significance for the innovative design of the band saw equipment, the applications of new technologies to improve the design efficiency, technical level and competitiveness of the band saw equipment, the reduction of costs and the shortening of the design cycle.
