Fault Damage Power and Self-recovery System of Machinery
Animals possess the function of self-recovery for adapting the change in their living conditions.Can machinery,by bionic design,just like animals,also possess the function of self-recovery for making itself free of fault,or for eliminating fault automatically during operation? In this paper,a new theory of Engineering Self-recovery is discussed,which could provide theoretical basis and new methodology for creating a new generation of machinery with fault self-recovery function.The engineering self-recovery theory is different from engineering cybernetics.Engineering cybernetics endows machinery with purposive behavior which originally is one of animals common characteristics,while engineering self-recovery theory endows machinery with the new function of fault self-recovery which originally is another one of animals common characteristics.Under the guidance of engineering cybernetics,the automation of machinery has come true.While under the guidance of engineering self-recovery theory,a new generation of machinery with the new function of fault self-recovery could also be realized.The self-recovery system,which can provide fault self-recovery force to restrain fault force,is investigated in detail.Based on fault mechanism and risk analysis,and by bionic design,a fault self-recovery system,which is a dynamic system to store,supplement and transfer the self-recovery force,is endowed to a machine with the ability to maintain the machine in a health state.Also,the research in engineering application of the new concept,fault self-recovery,is on the way.As an example,the new concept centrifugal compressor with fault self-recovery function is discussed here with axial displacement and flow induced vibration fault self-recovery as examples to show the steps of fault self-recovery system construction such as fault mechanism,necessity,determination,possibility,fault tolerance,limitation and execution.
