Research progress of curved plates in China. I: Classification and forming methods

Abstract

This paper expounds the classification, modelling and preparation methods of curved plates in China and emphasises the characteristics and application examples of various forming methods for developing a bionic curved plate. The forming methods of curved plates can be divided into three major categories – stress forming, solidification forming and composite forming. The integrated classification system of a curved plate is given in this paper. Due to the complexity of surface morphology and preparation methods, the creation of a systematic classification of surface plates and their preparation methods remains an area for further study. The characteristics of various stress forming methods are explained, providing a beneficial reference for engineering applications. However, these methods are dependent on the operator's experience and a future research topic is to promote mechanisation, automation and intelligence. Several engineering application examples and the identification of solidification forming are described, which provide a direct reference for buildings with tall and complex curved surfaces. How to develop common and individual technologies for curved plate forming will be the research focus of curved plate forming methods in the future.
