EPLAN中元器件3D宏的创建与应用

EPLAN软件作为专业的电气设计软件,其3D布局设计、布线设计功能广泛应用于电气项目的设计中。EPLAN软件中,元器件的3D宏的创建是进行3D布局设计和布线设计的核心。本文从设备的3D模型转化、定义安装和连接信息等方面,详细介绍软件中3D宏的建立方法,为控制柜三维布局设计软件的应用提供参考。

Coupled 3D discrete-continuum numerical modeling of pile penetration in sand

A coupled discrete-continuum simulation incorporating a 3D aspect and non-circular particles was performed to analyze soil-pile interactions during pile penetration in sand.A self-developed non-circular particle numerical simulation program was used which considered sand near the pile as interacted particles using a discrete element method;the sand away from the pile was simulated as a continuous medium exhibiting linear elastic behaviors.The domain analyzed was divided into two zones.Contact forces at the interface between the two zones were obtained from a discrete zone and applied to the continuum boundaries as nodal forces,while the interface velocities were obtained from the continuum zone and applied to the discrete boundaries.We show that the coupled discrete-continuum simulation can give a microscopic description of the pile penetration process without losing the discrete nature of the zone concerned,and may significantly improve computational efficiency.
