Cut file, sawing skills by learning the grip, standing position, body movements, and many other points force factors and the impact of the traditional grip of the emergence of file-grip handle to stand up after slightly outside the site of the palm, when a file cut Force, after the file handle a gradual shift,"hold" to "grasp", resulting in the introduction file enough; saw grip handle full point higher than the thrust of the saw blade to install center hole of about 30mm, the high point of thrust is likely to result in the bow saw On both sides of the swing, resulting in a broken saw blade and saw seam askew.

锉削、锯削技能的学习是受握法、站立部位、身体动作、作用力点等诸多因素的制约和影响的，传统的握法出现握锉柄后顶住部位稍偏离手心，锉削时一用力，锉柄逐渐后移，&握&变成&抓&，造成锉刀推出力度不足；满握锯柄的推力点高于锯条安装孔中心约30mm，偏高的推力点很容易造成锯弓向两侧摆动，造成锯条折断及锯缝歪斜。

Wave is the rotor blades hinges on the hinge between the propeller blade hub, the hinge allows the blade perpendicular to the rotor plane up and down waving, in order to make it not have chatter and the shutdown will not touch the ground, usually limited to damping and compatible digital devices ...

On the basis of analyzing the theory of the modeling of the propeller surface, this paper transforms the section data given by design to the data in Descartes coordinates. Interpolates the section data to get enough data and fits the blade surface with the least square method. A perfect C2 blade surface can be obtained by adjusting the deviation weight and fairing weight. According to the cylinder rough, two rough cut methods are preferred.

本论文在深入分析螺旋桨曲面成型原理的基础上，将设计时给定的桨叶曲面的切面数据转化为笛卡尔坐标系中的坐标，利用B样条方法对截面数据点插值并加密，得到足够的数据点，进而利用最小二乘法拟合出桨叶曲面，通过调整偏离权和光顺权得到了理想的二阶连续的桨叶曲面。

An equal cross-section blade was investigated and a finite element model was built parametrically. Geometrical parameters (such as length, width and thickness), material parameters (such as young's modulus and density) and speed of blade were considered as input random variables while the static frequencies and dynamic frequencies were output random variables. Combining the finite element method, response surface method and Monte Carlo method, the statistical properties and cumulative distribution functions of static frequencies and dynamic frequencies were obtained. Probability sensitivities analysis, which combined the slope of the gradient and the width of the scatter range of the random input variables, was applied to quantitatively evaluate the sensitivities of static frequencies and dynamic frequencies with respect to the random variables. The Scatter plots of structural responses with respect to the random input variables were illustrated how to adjust the values of the static frequencies and dynamic frequencies by changing input random variables.
