The algorithm can give the solution of resultant finite element equations by means of the combination of direct Crout decomposition method and blocking technology. Thereby, we have solved the problem that the computer stops running the program because of not enough memory. 该算法采用直接法中克劳特分解法与分块技术相结合来求解已合成的总体有限元方程组,从而解决了计算机因内存有限而使程序经常死机的问题。
The empirical formula of the mean cutting component of the resultant forces was analysed by computer using a program of linear regression. In addition, the noise in the cutting condition was compared to the noise in the idle run. 工件进行车削试验,用计算机按多元回归程序打印出切削力经验公式,同时测定切削状态和空转状态的噪音,并进行了比较。
Because the resultant graph is third dimension, it can directly check the accuracy of NC program, also make NC programmer check collision and interference, verify NC program by the graphics display. 由于产生的图形是真实感效果图,数控编程人员和机床操作者能够通过图形显示进行干涉和碰撞检查,校验数控程序。
