(1)三维有限元方法用于研究不规则物体是一种有效、准确的数值方法，不仅能考虑到所研究物体的几何形状，而且也考虑到物体的内部结构特性；股骨颈处的压力骨小梁和股骨距是重要的承载结构，内固定物的放置应循压力骨小梁方向尽量紧贴股骨距钻入；载荷主要通过压力骨小梁和股骨距传导至股骨干的中下1/3处；一定角度的下肢外展（10-30°）会较明显的增加股骨颈区的应力，而下肢的内收反而会减小此区的应力；暴力作用时股骨上端应力分布特点从生物力学角度说明老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

Shutdown, removed the row fan, fan struck by hand, the sense of rotation of the fan is very flexible, so use flat screwdriver inserted under the roots of the gap fanleaf bend to the will of the fan and fan-Block separation and jumped over the fan, the fan to see in the center of a small arc with several magnet surrounded a round shield-shaped, it is clear that this is the fan motor rotor, while the stator is fixed together with the fan-Block a micro-winding, if the fan and fan blocks together, the micro-coil is inserted to the internal rotor.

关机，将该排风扇拆下，用手拨动扇叶时，感觉扇叶的转动很不灵活，故用平头起子插入扇叶根部底下的缝隙内向上翘，将整个扇叶与扇座分离，翻过扇叶时，看到在扇叶的中心部位有一个用数条小弧形磁铁围成的圆罩形，显然，这就是该风扇电机的转子，而定子是与扇座固定在一起的一个微型绕组，若将扇叶与扇座组合在一起，则该微型绕组正好能插在转子的内部。

The technical characteristics of the invention is that: the rotor end face tooth profile contains four, five or six sections of tooth curves with the circular nature; when it has five sections, addendum circular arcs and dedendum circles are added to the addendum or the dedendum of the rotor; when it has six sections, both the addendum circular arcs and the dedendum circles are added to the addendum and the dedendum of the rotor at the same time, to form four different combination schemes; there are common tangents at the connection points of the two adjacent teeth forming curves, which has a smooth tooth-profile without cusp, a high-wearing feature, a long life of the rotor, a small leakage triangle, and a good sealing property.

本发明的技术特征是：转子端面齿型是包含四段、五段或六段圆弧性质的齿曲线；当为五段时，在转子的齿顶或齿根加上齿顶圆弧或齿根圆弧，当为六段时，在转子的齿顶和齿根同时加上齿顶圆弧和齿根圆弧，形成四种不同的齿型组合方案；相邻的两组成齿曲线的连接点处具有公切线，齿型光滑，没有尖点，耐磨性好，转子的使用寿命长，泄漏三角形小，密封性好。

The wavelet time-frequency features of the cracked rotor and the uncracked rotor were discussed, and the difference between them was presented.

将小波分析方法引入到裂纹转子时频特性研究中，得到了有无裂纹转子的小波时频特性，并讨论了它们的差别。

The analysis results indicate that the vibration fractional factor with rotating frequency has a close relationship with both rotating speed of rotor and damping of bearing under constant acceleration. When rotating acceleration is small and damping is large, the transient response is not sensitive to the variation of rotating speed; otherwise the imbalance response with constant acceleration and the response in stable state will build up obvious differences near critical rotating speed.

研究结果表明：在恒加速条件下，转子同频振动分量与转子的转速、支承阻尼等因素密切相关，当角加速度较小且阻尼较大时，其瞬态响应对转速的波动不敏感；而当角加速度较大或阻尼较小时，恒加速过程不平衡响应与稳态响应在临界转速附近将产生明显的差异。

The rotor and its bearing, linked with small clearance restrict, makes up of the whole rotating system of unit power in ball pen production machine; its breakage and failure, first appear in the form of the failure of small clearance restrict, is caused directly by the unit vibration. Therefore, how to ensure good dynamic characteristics of rotating system is the thing worthy of note.

在多工位制笔机械的小动力头旋转系统中，转子与其支承之间是依赖小间隙约束而构成完整系统的，机组失效也总是最先表现在这类小间隙约束的破坏与失效上，而机组振动则是导致小间隙约束破坏的直接原因。
