Abstract

The study aims to investigate the mechanical system optimum design based on collaborative theory. Due to the complexity of the modern machinery, mechanical systems are readily to damage when unexpected failures occur on important components. It is therefore, critical to monitor the machine state for preventing the impending faults. The key issues to realize the feasible and reliable mechanical condition monitoring is information acquisition, which relies on the available design of the detection devices. Literature review indicates that an extensive attention has been put on the so called Monitorability in the systematic design of mechanical systems. Monitorability is emphasized that in the original design of mechanical systems one should consider available information acquisition property. Moreover, monitorability-based design is known as a design attribute of mechanical system worldwide. However, less work has been done in this field. In this study, a novel method based on collaborative theory is proposed for the monitorability design. The connotation and application of collaborative theory for monitorability design are discussed in details. The information synergy model and organization framework of monitorability-based design are established by using computer technology and network technology. The experiments demonstrate the effectiveness of the proposed monitorability design system for a more powerful optimum design of mechanical systems and show a promising future for the industrial applications.

Highlights

With the rapid development of science and technology, mechanical systems are growing larger, its working environment is becoming more complex and its importance is becoming more important (Zhang et al, 2010a; Zhang and Yan, 2010; Li et al, 2010, 2011a, 2011b, 2012a)
In order to deal with these challenges, some proprietary attributes of mechanical system are more required by users of mechanical system except performance requirements, function requirements and quality requirements of products
Reliability and intelligence of mechanical system is more attention based on accomplishing high-efficient and reliable operation and minimum the life cycle cost of mechanical system (Liang et al, 2009; Yan et al, 2010; Yu et al, 2010; Li et al, 2012b, 2012c)

Summary

INTRODUCTION

With the rapid development of science and technology, mechanical systems are growing larger, its working environment is becoming more complex and its importance is becoming more important (Zhang et al, 2010a; Zhang and Yan, 2010; Li et al, 2010, 2011a, 2011b, 2012a). Application and implementation of the theory has important significance to improve accuracy and technologies of condition monitoring, reduce maintenance costs and save security costs for mechanical system. Application and implementation of monitorability-based design has much something to do with design development, safe and reliable operation, maintenance comprehensive logistics safeguard and the life cycle cost of mechanical system. Application and implementation of monitorability-based design can improve accuracy, real-time and reliability of condition monitoring and fault diagnosis system for mechanical products system.
