The Equivalent Resistance Gradient Model of Metamorphic Mechanisms and the Design Approach

Abstract

The practical metamorphic process, which include configuration transforming, configuration keeping and working sequence problems, is introduced. The concept of equivalent resistance gradient of metamorphic joints is proposed to investigate a new way for regulating the constrained metamorphic process and/or design of metamorphic joints. A kinds of metamorphic cyclogram is introduced, and the resistance characteristics of typical metamorphic joints are studied. A non-dimension equivalent resistance coefficient of metamorphic joints and the equivalent resistance gradient model of metamorphic mechanism are defined. The connection ships of equivalent resistance, constraint characteristics and forms, and the structure of metamorphic joints in the working stages are revealed. A design approach is demonstrated based on the metamorphic cyclogram and the equivalent resistance gradient model.
