基于LabVIEW的基础激励随机振动仿真系统
Simulation platform of incentive-based random vibration based on LabVIEW
【摘要】 本文设计了一个基础激励随机振动仿真平台系统。具体介绍了系统主程序的设计思想和程序界面的操作流程。平台系统的主程序由较新的虚拟激励算法实现,加速了随机振动的计算效率,且能够方便处理复杂耦合的基础激励响应谱问题。系统的主界面在LabVIEW环境下设计,整个程序的操作完全界面化,操作简单,执行速度快。此外,平台显示仿真结果方便,改善了Fortran语言后处理数据功能不足的缺点。
【Abstract】 A simulation platform of incentive-based random vibration is designed in this paper.Specifically the system design concept and procedures of the main program interface is described.In order to improve speed,a new method with a high efficient in random analysis the Pseudo Excitation Method is used.Furthermore,it is realized for the complex coupling incentive-based random vibration problem.The main framework is built on LabVIEW and indicates the system has a friendly and comfortable interface.In addition,it makes up for the Fortran language’s shortcomings which is not convenient to display the simulation result.
