CST STUDIO SUITE 2018 -电缆模拟 3 Chapter 1 — Introduction 第一章——导言 Welcome 欢迎 Welcome to CST CABLE STUDIO, the powerful and easytouse package for analyzing conducted transmission, EMI (Electromagnetic Interference) and EMS (Electromagnetic Susceptibility) on complex cable structures. 欢迎来到 CST电缆工作室，这是一个强大而易用的软件包，用于分析复杂电缆结构上的传导传输、电磁干扰和电磁敏感度。 This program combines transmission line theory, circuit simulation and 3D "fullwave" calculation methods in a convenient and sophisticated way, which makes it highly suitable for simulating cables inside electrically large systems. 该程序将传输线理论、电路仿真和三维“全波”计算方法以一种方便而复杂的方式结合起来，使其非常适合于模拟大型电力系统中的电缆。 CST CABLE STUDIO is embedded into the design environment of CST STUDIO SUITE, which is explained in the Getting Started manual.The following explanations assume that you have already installed the software and familiarized yourself with the basic concepts of the user interface. CST CABLE STUDIO被嵌入到 CST STUDIO SUITE的设计环境中，这在《入门手册》中有所解释。以下解释假设您已经安装了软件，并且熟悉了用户界面的基本概念。 How to Get Started Quickly 如何快速开始 We recommend that you proceed as follows: 我们建议您按照以下步骤操作:  I  I  I 

I Read the CST STUDIO SUITE Getting Started manual. 阅读 CST STUDIO SUITE入门手册。 Work through this document carefully.It should provide you with all the basic information necessary to understand the advanced documentation found in the online help. 仔细阅读这份文件。它应该为您提供理解在线帮助中的高级文档所需的所有基本信息。 Look at the examples provided in the Component Library (File: Component Library 查看组件库中提供的示例(文件:组件库  Examples).Especially the examples which are tagged as Tutorial provide 的例子)。特别是被标记为教程提供的例子 detailed information of a specific simulation workflow.Press the Help button of the individual component to get to the help page of this component.Please note that all these examples are designed to give you a basic insight into a particular application domain.Realworld applications are typically much more complex and harder to understand if you are not familiar with the basic concepts. 特定模拟工作流的详细信息。按下单个组件的帮助按钮，进入该组件的帮助页面。请注意，所有这些示例旨在让您对特定应用领域有一个基本的了解。如果你不熟悉基本概念，现实世界的应用程序通常要复杂得多，也更难理解。 Start with your first own example.Create your first CABLE STUDIO model and simulation.Choose a reasonably small and simple harness that will allow you to quickly become familiar with the software. 从你自己的第一个例子开始。创建您的第一个 CABLE STUDIO模型和模拟。选择一个合理的小而简单的工具，让你快速熟悉软件。 What is CST CABLE STUDIO? 什么是 CST CABLE STUDIO？ CST CABLE STUDIO is an electromagnetic simulation tool specially designed for fast and accurate simulation of realworld cables inside electrically large systems by combining transmission line theory, circuit simulation and 3D fullwave calculation methods.It closes the gap between pure 2D cross section analysis and pure 3D full-wave analysis. CST CABLE STUDIO是一款电磁仿真工具，专门设计用于结合传输线理论、电路仿真和三维全波计算方法，快速、准确地模拟大型电力系统内部的真实电缆。它缩小了纯 2D截面分析和纯三维全波分析之间的差距。 CST CABLE STUDIO offers a user interface that makes it easy to define a complex cable harness.The 3D topology can be defined either from scratch or by loading an existing harness via a NASTRAN or STEP AP212KBL import filter.Separate dialog boxes enable the definition of four

basic types of cables: single wires, ribbon cables, twisted cables and shielded cables (compact, foil or braided shields). CST CABLE STUDIO提供了一个用户界面，便于定义复杂的电缆线束。3D拓扑可以从零开始定义，也可以通过 NASTRAN或步进 AP212KBL导入过滤器加载现有线束来定义。单独的对话框允许定义四种基本类型的电缆:单线、带状电缆、绞合电缆和屏蔽电缆(紧凑型、箔式或编织屏蔽)。 4 CST STUDIO SUITE 2018 - Cable Simulation 4 CST STUDIO SUITE 2018 -电缆模拟 Any combination of these basic cable types can be defined and stored in a user defined library.A couple of dialog boxes allow the convenient definition of exact or random cable cross sections. 这些基本电缆类型的任何组合都可以定义并存储在用户定义的库中。几个对话框允许方便地定义精确或随机的电缆横截面。 The transfer impedance of a shielded cable can be either directly defined or calculated by using the builtin transfer impedance calculator, which extracts the impedance from the geometric characteristics of the shield.In addition, it is possible to load and assign measured transfer impedance curves. 屏蔽电缆的传输阻抗可以直接定义，也可以使用内置传输阻抗计算器计算，该计算器从屏蔽的几何特性中提取阻抗。此外，可以加载和分配测量的传输阻抗曲线。 CST CABLE STUDIO generates equivalent circuits from the cable harness based on classical transmission line theory.It automatically meshes the cable harness along its length and calculates the transmission line parameters on these segments.Skin effect and dielectric loss are modeled in both frequency and time domain simulations.The equivalent circuits can be exported in several SPICE formats. CST CABLE STUDIO根据经典传输线理论从电缆线束中产生等效电路。它会自动沿线束长度对其进行网格划分，并计算这些线段上的传输线参数。集肤效应和介电损耗在频域和时域模拟中都进行了建模。等效电路可以几种 SPICE格式导出。 CST CABLE STUDIO uses the powerful 3D solid modeling front end of CST MICROWAVE STUDIO to set up or import arbitrary metallic 3D shapes, ranging from simple ground planes to complex chassis structures.Moreover, the powerful 3D full-wave solvers from CST MICROWAVE STUDIO are used to calculate the electromagnetic fields in the environment surrounding the cable. CST CABLE STUDIO使用 CST微波工作室强大的 3D实体建模前端来设置或导入任意金属 3D形状，从简单的接地面到复杂的底盘结构。此外，CST微波工作室强大的三维全波解算器用于计算电缆周围环境中的电磁场。 CST CABLE STUDIO uses CST DESIGN STUDIO's easytouse schematic to define passive and active devices at cable terminations.The powerful builtin network simulator in CST DESIGN STUDIO enables the simulation of a whole system consisting of the equivalent circuit of the cable harness and its terminations. 科技电缆工作室使用科技设计工作室的易用原理图来定义电缆终端的无源和有源器件。CST DESIGN STUDIO中强大的内置网络模拟器能够模拟由电缆线束及其终端的等效电路组成的整个系统。

CST CABLE STUDIO controls the data exchange between the circuit simulation engine and the various 3D EM solvers for currents (on the cable harness) and electromagnetic fields (around the cable harness).This enables simulating both the effects of fields coupling into the cables and fields radiating from the cables. CST CABLE STUDIO控制电路模拟引擎和各种 3D电磁解算器之间的数据交换，用于电流(在电缆线束上)和电磁场(在电缆线束周围)。这使得能够模拟耦合到电缆中的场和从电缆辐射的场的影响。 Applications 应用程序  I  I  I Transmission and crosstalk simulations of extended cable structures in time and frequency domains 扩展电缆结构在时域和频域的传输和串扰模拟 EMI: analysis of radiated electromagnetic fields from complex cables lying along metallic structures 电磁干扰:沿金属结构敷设的复杂电缆辐射电磁场的分析 EMS: analysis of coupled electromagnetic fields into complex cables lying along metallic structures 电磁搅拌:分析沿金属结构排列的复杂电缆中的耦合电磁场 CST STUDIO SUITE 2018 - Cable Simulation 5 CST STUDIO SUITE 2018 -电缆模拟 5 CST CABLE STUDIO Key Features 科技有线电视演播室的主要特点 An overview of the main features of CST CABLE STUDIO is provided in the following list.Please note that availability of some of the listed features may depend on the individual license configuration.Please contact your local sales office for details.
