The main jobs of this paper are as followed: 1 The reuse of the frame design technology for aircraft assembly fixtures is researched. a frame line part library is built with the templet driven technology, the reuse of the frame line part come true by the tools for instantiation and instance modification. The design resources are effectively used, some repeating work is cut. 2 Two methods to obtain the assembly feature are proposed: the straight way by the Enumeration method and the indirect way by project features to the assembly plane. All of the assembly features of the frame and the adjustable bearings are obtained by these two methods which makes the frame automatic assembly technology for aircraft assembly fixtures come true. 3 The frame automatic assembly technology aircraft assembly fixtures based on assembly features is researched. A binary tree assembly model is used to express the assembly information of the frame for aircraft assembly fixtures, the automatic assembly between the frame, the aircraft and the adjustable bearing is completed within the three steps: distribute, obtain and evaluate assembly feature. Finally, the efficiency of the frame assembly design is proved. 4The frame interpart modeling technology for aircraft assembly fixtures is researched, the intersection methods are concluded and the arithmetic of the single-cut, double-cut and inter-cut intersection is proposed, the interpart fast modeling of the frame design for aircraft assembly fixture come true. 5Based on the researches mentioned before, a sub-system of frame fast design for aircraft assembly fixture is developed on CATIA. The sub-system is used to design the aircraft assembly fixtures in a large aeronautics corporation and make a good- effect.

论文的主要工作如下： 1研究了飞机装配型架骨架设计重用技术，在总结归纳骨架线框结构类型的基础上，应用模板驱动的方法建立了骨架线框库，通过骨架线框零件的实例化和离线编辑实现骨架线框的重用，有效利用设计资源，减少重复劳动； 2提出穷举几何对象的装配特征直接获取方法，遍历零件模型的几何对象，从中捕捉所需装配特征，该方法简捷、高效；提出向装配面投影的装配特征间接获取方法，该方法在现有特征基础上生成装配特征，解决了部分装配特征难以直接获取的问题； 3研究了基于装配特征的飞机装配型架骨架自动装配技术，采用一种二叉树装配模型表达骨架的装配关系，并通过装配特征的分配、获取和赋值三个步骤，实现了骨架分别与飞机产品和可调支承的自动装配，避免了繁琐的人工交互操作，提高了骨架设计的效率和规范化程度； 4研究了飞机装配型架骨架零件间建模技术，在总结归纳骨架元件相贯处理方式的基础上，提出了骨架元件单剪切相贯、双剪切相贯和互剪切相贯的实现算法，简化了骨架相贯处理的过程； 5基于以上研究，在CATIA平台上开发了飞机装配型架骨架快速设计子系统，并应用于某大型航空企业的装配型架设计，提高了设计效率和设计质量。

On moving base, a new initial alignment algorithm for strapdown inertial navigation system is proposed. In the algorithm, two special inertial frames, the initial-time inertial frame (i0 frame) and the initial-time SINS body inertial frame (ib0 frame), are defined and are selected as calculation reference frames, then, the calculation of initial alignment direction cosine matrix is expanded into three parts:(1) the DCM between i0 frame and the navigation frame will be easily obtained via local geographical coordinates and initial alignment time;(2) attitude updating using gyro samples gets the DCM between SINS frame and ib0 frame;(3) by explaining SINS specific force equation in SINS body frame, the relation between velocity log, accelerometer measurement and gravity acceleration is established to achieve the constant DCM from ib0 frame to i0 frame.

在运载体运动情况下，提出了一种适用于捷联惯导系初始对准的新算法，该算法以惯性空间为参考基准，即建立了初始时刻惯性坐标系（i0系）和初始时刻捷联惯组惯性坐标系（ib0系）两个惯性坐标系，将初始对准姿态矩阵的实现分解为三部分：（1）通过地理位置和初始对准时间求解i0系至导航坐标系的变换矩阵；（2）使用姿态更新算法实时计算捷联惯组相对于ib0系的变换矩阵；（3）通过惯导比力方程变形，获得测速仪辅助测量、加速度计输出和重力加速度之间的关系，从中可以求解出从ib0系至i0系的常值变换矩阵。

Y0u'll be the only one; We meet in the night in the Spanish café I look in your eyes just don't know what to say It feels like I'm drowning in salty water A few hours left 'til the sun's gonna rise tomorrow will come an it's time to realize our love has finished forever how I wish to come with you how I wish we make it through Just one last dance before we say goodbye when we sway and turn round and round and round it's like the first time Just one more chance hold me tight and keep me warm cause the night is getting cold and I don't know where I belong Just one last dance The wine and the lights and the Spanish guitar I'll never forget how romantic they are but I know, tomorrow I'll lose the one I love There's no way to come with you it's the only way to do Just one last dance before we say goodbye when we sway and turn round and round and round it's like the first time Just one more chance hold me tight and keep me warm cause the night is getting cold and I don't know where I belong Just one last dance Oh,Baby Just one last dance before we say goodbye when we sway and turn round and round and round it's like the first time Just one more chance hold me tight and keep me warm cause the night is getting cold and I don't know where I belong Just one last dance before we say goodbye when we sway and turn round and round and round it's like the first time Just one more chance hold me tight and keep me warm cause the night is getting cold and I don't know where I belong

你是唯一的我们相会于夜间在西班牙咖啡厅我期待你的眼睛里，只是不知道该说些什么感觉就像我溺死在咸水几个小时左'的TIL太阳的崛起在哪里明天会来一个，它的时间去实现我们的爱情已经结束永远我多么希望您同来我多么希望我们可以通过刚才最后一个舞蹈然后，我们说再见当我们摆度转身和打转这就像第一次只是多一个机会持有我紧，让我温暖事业夜越来越冷我不知道我是属于刚才最后一个舞蹈葡萄酒及灯光和西班牙吉他我永远不会忘记如何浪漫，他们是但我知道，明天我将失去我的爱有没有办法来与你它这样做的唯一方法刚才最后一个舞蹈然后，我们说再见当我们摆度转身和打转这就像第一次只是多一个机会持有我紧，让我温暖事业夜越来越冷我不知道我是属于刚才最后一个舞蹈哦，宝宝刚才最后一个舞蹈然后，我们说再见当我们摆度转身和打转这就像第一次只是多一个机会持有我紧，让我温暖事业夜越来越冷我不知道我是属于刚才最后一个舞蹈然后，我们说再见当我们摆度转身和打转这就像第一次只是多一个机会持有我紧，让我温暖事业夜越来越冷我不知道我是属于
