雕塑建模特点和结构布置原则!

来源:http://www.aswjc.com/ 发布人:admin 发布时间:2020-06-29

  由于雕塑雕像结构的外形无论在平面还是立面方向都特别复杂,因此其内部结构的有限元建模工作要比一般的规则结构困难得多。
  Because the shape of sculpture structure is very complex in both plane and elevation direction, the finite element modeling of its internal structure is much more difficult than the general regular structure.
  其基本原则是:建模必须充分考虑外轮廓壁板的次安装,即杆件和节点的布置,在预留一定的安装空间后,必须满足外形要求。具体布置方法是,依据像体外形的电子扫描曲线(通常沿高度方向每隔0.2~0.5m截取一根曲线),在每隔2m左右的一层曲线范围内布置杆件和节点,每个节点离外轮廓曲线的近否则不能满足二次安装壁板的空间要求。节点之间距离,一般应控制在350~1布置的杆件,应尽量形成三角形的几何不变体系,特别需要指出的是,在进行结构平面布置时,对于沿曲线方向的外圈边梁,由于直接承受二次外挂壁板传来的扭矩,其截面形式宜采用具有良好抗扭性能的封闭型截面,如方钢管、圆钢管等,不宜采用角钢或H型钢等开口截面。
  The basic principle is: the secondary installation of the outer contour panel must be fully considered in the modeling, that is, the arrangement of members and nodes. After a certain installation space is reserved, the shape requirements must be met. According to the electronic scanning curve of the image shape (a curve is usually cut every 0.2-0.5m along the height direction), the members and nodes are arranged within the curve range of about 2m, and each node is closest to the outer contour curve, otherwise the space requirement for secondary installation of wall panel cannot be met. Generally, the distance between nodes should be controlled between 350-1 bars, and a triangle geometry invariant system should be formed as far as possible. In particular, for the outer ring side beam along the curve direction, the section form of the closed section with good torsion resistance should be adopted, for it directly bears the torque from the secondary external wall panel, such as square Steel pipe, round steel pipe, etc., should not use angle steel or H-section steel.

  在各层平面的结构布置完成后,再进行竖向结构的布置,即沿像体高度方向连接各层平面上的节点,基本沿竖向的构件按柱截面设置,一般采用H型钢或箱形截面,并注意其主轴的放置方向,斜向的构件按纵向支撑设置,通常采用等边或不等边的双角钢截面也可采用圆钢管、方钢管或H型钢截面。
  After the structural arrangement of each floor plane is completed, the vertical structural arrangement shall be carried out, that is, the nodes on each floor plane shall be connected along the height direction of the image, and the vertical components shall be set according to the column section, generally H-shaped steel or box section shall be adopted, and the main axis shall be paid attention to, the oblique components shall be set according to the longitudinal support, and the equal or unequal double angle steel section can also be adopted Circular steel pipe, square steel pipe or H-section.
  这里需要注意的是:
  Here we need to pay attention to:
  ①在连接像体外围的竖向构件时,由于某两层曲线之间像体的实际外轮廓可能存在内凹部分,此时该处的某些构件可能会与二次安装的壁板位置相冲突即所谓的“犯界”
  ① When connecting the vertical components around the image, there may be a concave part in the actual outer contour of the image between two layers of curves. At this time, some components may conflict with the position of the second installation of the wall panel, which is called "boundary breaking"
  ②在雕像的身体与头,颈部轮廓突变处,应将杆件的网编织密切不能留有任何不牢固。
  ② In the body and head of the statue, where the contour of the neck changes, the net of the rod shall be woven closely without any unsteadiness.
