Exact shell solutions for conical springs. III. Belleville springs with variable thickness

In the current dataset, we examine the Belleville spring with the variable thickness. The thickness is assumed to be variable along the meridional and parallel coordinates of conical coordinate system. The calculation of the Belleville springs includes the cases of the free gliding edges and the edges on cylindric curbs, which constrain the radial movement. The equations developed here are based on common assumptions and are applicable to the industrial calculations. There are 10 models with the different thickness distributions of the material thickness over the radius of the surface. For each model, the three load cases were simulated. One load case represents the freely gliding edges of the spring. Another load cases constrain the radial movement of inner or outer edge of the middle surface. The input files in ANSYS APDL language are saved for each model and each load condition. All APDL files are in the archive ANSYS.zip. The APDL files are used for the simulation with program ANSYS. The EXCEL files in the archive telle3.1.zip represent the results of finite-element simulations with the program ANSYS 2023.R2. The vertical reactions on the inner edge are stored in the file telle3.1.zip. These EXCEL data will be imported in MAPLE source file. With this MAPLE source file the comparison between the closed form solutions and finite-element analysis is performed.本数据集针对变厚度碟形弹簧（Belleville spring）展开研究。假设该弹簧的厚度沿圆锥坐标系（conical coordinate system）的子午坐标与环向坐标呈变分布。碟形弹簧的计算工况涵盖自由滑移边界与圆柱约束边界两类，其中圆柱约束边界可限制径向位移。本研究推导的公式基于通用假设，可应用于工业计算场景。本数据集包含10种不同表面半径方向材料厚度分布的模型，针对每个模型均模拟了3种载荷工况：其一对应弹簧的自由滑移边界，另外两种工况分别约束弹簧中面内边缘或外边缘的径向位移。针对每个模型与每种载荷工况，均保存了ANSYS APDL语言编写的输入文件，所有APDL文件均归档于ANSYS.zip压缩包中，用于借助ANSYS软件开展仿真计算。归档文件telle3.1.zip中包含的EXCEL文件，记录了基于ANSYS 2023.R2版本开展的有限元仿真结果，其中存储了内边缘的竖向反力数据。上述EXCEL数据将导入至MAPLE源文件中，借助该源文件即可完成解析解与有限元分析（finite-element analysis）结果的对比验证。
