It showed the correctness of the criteria of roundness error and relationship between the minimum zone circle, minimum circumscribed circle and maximum inscribed circle and the effectiveness of the methods for evaluation of roundness error.

也验证了圆度误差判别准则及最小区域圆、最小外接圆和最大内接圆特征点间的相互关系的准确性和误差评定方法的有效性。

Thus, evaluation of the minimum zone circle could be solved effectively.Three methods of assessment of roundness error were proposed in this dissertation. Based on the criteria of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle and convex hull, a unified approach was proposed to evaluate roundness error of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle. Evaluation of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle was fulfilled with rotation based the contact pattern. The minimum circumscribed circle and maximum inscribed circle were evaluated with curvature and the curvature circle.

本文提出了三种圆度误差评定的方法：根据最小区域圆、最小外接圆、最大内接圆在极坐标系下的判别准则，利用计算几何中的凸壳理论，提出了一种统一的评定方法，实现了对最小区域圆、最小外接圆、最大内接圆的误差评定；基于接触斑点的检验原理，利用旋转法，实现了最小区域圆、最小外接圆和最大内接圆的误差评定；利用曲率和曲率圆，实现了对最小外接圆和最大内接圆的误差评定。

The some basic methods in composite mechanics are introduced,and relative formulations are derived.Maximum stress criterion,Maximum strain criterion,Hill criterion and Cai-Wu criterion are showed.The solid model of level-stability-panel is built by CATIA software,its finite element model by PATRAN/NASTRAN software.Through finite element analysis,the stresses and displacements of level-stability-panel are obtained.In order to analyze the strength of asingle part of level-stability-panel,the software CLOP is developed.The process of taking the data from NASTRAN's results and importing them to CLOP is showed.The strength of back wall of lev el-stability-panel is calculated by CLOP.

论文叙述了复合材料力学分析的基本方法，并推导了相应的计算公式，给出了几种常用的强度准则；利用CATIA软件对某型直升机的平尾进行实体建模，然后在PATRAN/NASTRAN软件中读入该模型，形成了有限元分析模型，并进行有限元分析，获得了平尾的应力云图和位移云图；为了对平尾的局部复合材料结构进行强度分析，开发了CLOP程序；从平尾结构中取出后樯作为强度分析的对象，表示了从NASTRAN分析的结果到CLOP程序输入的方法，计算出了后樯的强度数据。
