查询词典 hyperboloid

In this paper, a new method for aspheric conicoid machining is offered by using normal equidistance line offsetting methods.1、Obtain ecumenic equation of normal equidistance offsetting line methods for aspheric conicoid machining induced from mathematical equations of paraboloid, hyperboloid and ellipsoid surface; reason the conditions for avoiding of tool intervening.2、Bring forward the general design project for machining tool together with some primary components based on the conception of non-sphere conicoid machining by using normal equidistance line offsetting.

其主要内容有： 1、进行了二次旋转曲面法线等距离线加工方法的理论研究，分别建立了抛物面、椭球面和双曲面的法线等距离线模型，得出了避免加工过程中刀具干涉的必要条件。 2、根据法线等距离线加工法的理论，确定了二次旋转曲面加工机床的总体设计方案，并进行了零部件的选择。

In order to maximize change in the past vertical building structures, and overthrow the original shape influenced by it, these houses are anticlockly turned by 15 degree, supported and connected with 8 inclined steel columns. A core shaped-hollow construction is built to stand in the middle of this building to accomplish the rotating construction as the final formation. The outer curtain wall is hyperboloid metal net, which helps to form an overall rotation effects and well-protected the privacy of the residents.

为了最大限度的改变以往的垂直建筑结构，推翻在其影响下的建筑形态并满足面积为12*12的要求，我把每层的楼板按逆时针旋转15°并用8根钢柱连接，辅助斜向钢柱加以支撑，配合核心筒最终形成旋转的建筑结构，外表皮为双曲面金属网，能够有形成整体的旋转效果并很好的保护室内居民的隐私。
