Affine Frames of Multivariate Box Splines and their Affine Duals
      
We investigate the fractal interpolation functions generated by such a system and get its differentiability, its box dimension, its packing dimension, and a lower bound of its Hausdorff dimension.
      
At last, we discuss the series expressions of these functions and give a Box-counting dimension estimation of "critical" fractal interpolation functions by using our smoothness results.
      
The Box dimension, Packing dimension and Hausdorff dimension of such surfaces are investigated.

The conception of "the trace model of power flow" given in this paper has been pointed out to the analysis of the construction types and their specific characteristics of gear box for fixed shaft in step gear transmission. In accordance with the trace model of power flow, various kinds of gear boxes can be classified into four basic types so as to establish a series of tractor transmission gear box.According to "the trace model of power flow" as stated in the paper, the establishment of transmission...

The conception of "the trace model of power flow" given in this paper has been pointed out to the analysis of the construction types and their specific characteristics of gear box for fixed shaft in step gear transmission. In accordance with the trace model of power flow, various kinds of gear boxes can be classified into four basic types so as to establish a series of tractor transmission gear box.According to "the trace model of power flow" as stated in the paper, the establishment of transmission construction series, by the usage of its specified feature, is helpful to the design of new systematic gear box and also to improve the present used gear box construction. Furthermore, it offers as a referential principles to justify the various kinds of gear-box constructions.

本文提出按“功率流印迹模型”分析定轴齿轮传动有级变速箱的结构型式及其特点,将各式各样变速箱按功率流传方式归并为四个基本类型,依此建立拖拉机变速箱结构谱。 文章阐明按功率流印迹模型建立的结构谱,有助于设计工作的进行,有助于系列化设计和对现有结构进行改进,并为评价各类变速箱结构提供可参考的准则。

This paper presents the synthesis of path generating mechanisms as a constrained optimazation problem. General design equations are derieved whilh can be applied successively to the synthesis of 4-bar, 6-bar or linkage with more links. The optimum set of dimensions of a mechanism are determined by using a program based upon the Complex method of Box, The effectiveness of the method is illustrated by several examples.

The stress of the connective part of the thin-wall beam system is analysed by the finite element method. In the analysis,the connective part is divided into many triangular plate elements. For the membrane stress state the constant strain element (the displacement function is the linear function of cartesian coordinates) is used and for the heading stress state the constant curvature element (the displacement function is the cubic function of the area coordinates)is used. Then,as a shell the connective part...

The stress of the connective part of the thin-wall beam system is analysed by the finite element method. In the analysis,the connective part is divided into many triangular plate elements. For the membrane stress state the constant strain element (the displacement function is the linear function of cartesian coordinates) is used and for the heading stress state the constant curvature element (the displacement function is the cubic function of the area coordinates)is used. Then,as a shell the connective part is computed. A node of the plough frame (the connective part that consists of the beams with box section) and a node that consists of the beams with channel section are computed and analysed by this method.

本文用有限单元法对薄壁杆系连接部分进行了应力分析,分析中将结点区域离散为三角形平板单元,单元位移模式采用平面元和板弯曲元的组合,平面应力状态采用常应变单元,板弯曲应力状态采用面积坐标表示的三次元,按薄壳有限元法进行计算。用此法分别对犁架接头(一种闭口矩形管接头)和一种槽钢截面杆组成的结点进行了计算和分析。
