杉原条的数学模型

MATHEMATIC MODEL OF CHINESE FIR TREE LENGTH

贮木场生产过程自动化,利用电子计算机控制已成为木材采运企业的一个主要发展趋势。但是,使用电子计算机进行生产过程的优化和自动化控制,必须对加工对象建立数学模型。为此,进行了数学模拟方法的探讨,以建立木材(原条)的数学模型。 由于在造材过程中,主要关注的是原条的外形,因为造材方案的确定和出材率的高低都与树木的外形相关,所以原条的数学模型要用原条(树干)外形干形母线方程来表示(见图1)。

Mathematic model of tree bole (tree length) form is the necessary condition for computers to control and automatize bucking process. This thesis has investigated the method of setting the mathematic model of tree bole, and on the basis of investigation, the mathematic model of Chinese fir tree length has been set up. On this basis, the general method of setting the mathematic model for tree bole of various species is inferred.
