  cam profile
A method is presented to determine the location and magnitude of cam profile errors.
      
A recursion formula for the cam profile errors is derived using a finite-difference scheme.
      
The mathematical cam profile must be interpolated at some increment to create the numerical data for CNC machining.
      
Using piecewise polynomials, the complete cam profile can be designed as a combined linear system.
      
The system can be used to generate the cam profile, transmission angle, position, velocity, and acceleration of the follower.

Utilizing a cylindrical cam framwork as the main output power of down-raiser was found to provide such strong points as large output, low impact, and high feed-on rate. A comparison with other means, using ADAMS mechanical system simulation software, shows that a cam profile designed by spline interpolation possesses perfect theoretical ASU, AS·U and J. And design precision can be improved by increasing the number of points. At the same time, it effectively solves the problem of rigid impact or flexible impact,...

Utilizing a cylindrical cam framwork as the main output power of down-raiser was found to provide such strong points as large output, low impact, and high feed-on rate. A comparison with other means, using ADAMS mechanical system simulation software, shows that a cam profile designed by spline interpolation possesses perfect theoretical ASU, AS·U and J. And design precision can be improved by increasing the number of points. At the same time, it effectively solves the problem of rigid impact or flexible impact, making interpolation an effective means for designing destination curves.

采用圆柱滚子直动凸轮机构作为扬弹主动力输出机构,以保证新型舰炮下扬弹机构具有加速性能好、输出动力大、运转机构冲击小等优点。对比常用供弹机构设计曲线,及应用多体动力学软件-ADAMS进行的性能实验表明:样条插值方法设计的凸轮轮廓线具有理想的理论加速度¨S、理论速度·S、理论跃度J值;增加插值点数目,可以提高曲线的计算精度;有效地解决了在高速、重载条件下凸轮机构刚性冲击和柔性冲击大的突出问题.因而,插值法适合应用于获得不同条件下的预期运动规律曲线的设计.
