A STUDY ON THE METHOD FOR THE PORT MACHINE SAFETY DESIGN BASED ON STRUCTURAL INTEGRITY
This paper introduces the design methods and the actuality of the port machine structures and the main failure types of the existing port machines are analyzed. So far the most of the designers didn’t consider the existed defects’ in the structures influenced on the machines’ safety, and in fact a lot of port machines’ structures became failure as a result of ignoring these defects. In view of these conditions this paper brings a new method for designing the port machines’ structures based on the failure analysis theory. This method was put forward with combination of failure analysis theory and specifications of safety assessment according to many engineers’ practical experiences and a lot of tests’ results. When we design a structure we can suppose that one or more defects have existed in the structure, then according to the stress, the material’s capability, apply the failure assessment curve (FAC) to assess the structure’s safety. After the machine is manufactured we measure the key stress points’ defects, once the defects exceed the case which we supposed, we can consider that the machine is not safe to be used. In the end a typical example of this approach is presented.
