Parametric design and static behaviour analysis of single-layer conical shell

摘要

The parametric design macro programs of two basic types of single-layer conical shell are developed by using APDL(Ansys Parametric Design Language) parameterized design language. The parametric design of single-layer conical shell structures can be built under the condition of giving the macroscropic geometric parameters such as specifical span S, rise f, valley number Kn, radial node number Nx etc. Ansys software is applied to study comparison of characteristics of the structure of different vector height f and boundary constraintson. The results show that modeling design of conical shell can be built conveniently and quickly by the application of parametric design. The three-way grid is more reasonable force performance than Kiewitt. Thus it is suggested to give priority in the project.
