应用TCL/TK语言对柔性悬挂接触网系统的界面开发及相关动态分析算例
|
摘要
本文使用TCL/TK语言,编制基于ANSYS软件的界面程序,实现了接触网系统的参数化建模和各种分析功能(静态动态疲劳)融入一个主界面中,实现了方便,简易操作。
在本课题中,主要是集中利用了组件库中的一些组件程序,达到两个目的:第一个是实现了各个分析功能列在一个开发的界面中,通过点击不同的分析功能按钮实现进入各个不同的分析状态,第二个就是通过变量的互调和ANSYS软件发生联系,从而实现了各种分析中相关的参数数值的更改和调用。
针对柔性悬挂接触网系统,TCL/TK语言编制的主界面程序中包括以下几个模块:1、接触网系统模型建立所需的参数的输入;2、静态分析及后处理的查看;3、动态分析及后处理的查看;4、疲劳分析及后处理查看。
在主界面各个分析功能模块中,又包括了相应的各个不同的子模块,以实现更多参数的编辑。
通过进入各级界面的形式对各类参数进行设置并进入相关的分析模块对杆单元模拟的接触网系统进行了动态分析。分析了高速状态下影响弓网受流质量的因素,提出了弓网受流质量的技术指标,建立单弓/接触网有限元模型模拟了弓网动力耦合作用;利用有限元瞬态分析得到弓网间的接触力,并对跨距布置方式、列车运行速度、悬挂机构刚度、不同跨距、受电弓参数、接触网不平顺等因素对弓网间接触压力的影响进行了详细地分析。
In this paper, by using TCL/Tk, Intefaces procedures for analysis of flexible suspension overhead-catenary system are programmed to accomplish the follow functions including: parameterization input to create the finite element modle and which binds each sub-functions(static analysis、dynamic analysis、fatigue analysis) into the main intefaces,makes the operation convenient and have a very well eye-catching..
In this paper,we mainly write some tookits script and attain the two destinations:the first is binding each analysis functions into a single inteface,and only through clicking corresponding button which show the analysis function can entry each analysis states. The second purpose is link with ANSYS through transfering variables from entry which insall in the user-inteface.
Intefaces procedures based on ANSYS has a very clear direction. The objection of design is flexible suspension overhead-catenary system.for the diffrences of the analysis types,the main intefaces includes the following functions:1、system parameters input;2、static analysis and post-processor;3、dynamic analysis and post-processor;4、fatigue analysis and post-processor.
For each analysis module of the main inteface,in which nest correspoding sub-intefaces,through which can define more parameters for corresponding analysis types.
Define the parameters through the intefaces,and run the dynamic analysis module of theover-headcatenary system,and analogy the analysis results to the reality. The factors of current-carrying quality between pantograph and catenary at high speeds are studied and the necessary standards of the pantograph /catenary system are developed. The finite element model of pantograph /catenary system is established and the simple analysis and the comparison of the contact force are studied under the condition of the changes, such as the span of the catenary and the velocity of the locomotive.
The single dynamical model of couple pantographs/catenary systems is established and the contact force is calculated by means of limit element transient dynamic analysis. The analysis and the comparison of the contact force are studied in detail under the condition of the changes, such as the style of the span, the velocity of the locomotive, the stiffness of the rigid suspension, the span of the catenary, the parameters of the pantographs, and the catenary which is going unsmooth.
