Employing the method of complex helical drill point design,the formula of the clearance angle of inner cut edge for the socket drill is derived and the relationship between the clearance angle and the slantwise angle of the inner cut edge is deduced to innovate the design and manufacture of the socket drill.

通过复杂螺旋面钻尖设计方法导出锪窝钻钻尖内刃后角公式及内刃后角与内刃偏角的关系表达式，改进了锪窝钻的设计与制造。

However, due to disturbances caused by sea wind, sea wave, sea flow and some other uncertainties such as variance of ship physical parameters, how to control autopilots properly is a very difficult problem. An autopilot based on fuzzy logical control is proposed to make a ship follow the virtual course, which is calculated from real course and track deflection.

针对实际航向中，船舶受到来自海风、海浪、海流的干扰和船自身物理参数时常变化使得自动舵的控制变得困难的缺陷，提出了一种基于模糊逻辑控制的自动舵，并提出将期望航向角和航迹偏差共同计算得到的虚拟航向角作为新的期望航向角。

This thesis also improves the algorithm of iterative calculation of direct kinematics on two aspects. One is to solve the "floating" problem, which is the change of the leg lengthes when nuts of ballscrews rotate around their own axises.

通过对几类关键受限变量——杆长、关节摆角、倾倒角和旋转角进行相关运动学计算，实现对它们的限位约束；同时，针对因滚珠丝杠螺母副引起的杆长随角度变化而&浮动&的特殊问题，对正向运动学迭代算法进行改进，加快了收敛的速度； 3。
