多畴模拟:挖掘机的机械学和液压学(中文4600字,英文3300字,外文PDF)
概要:
通过使用用于多体和液压系统的Modelica程序库,示范通过Modelica和Dymola如何模拟和仿真挖掘机。液压系统由“负载传感”控制器控制。一般,模型包含难以模拟的三维机械和液压组件。对于挖掘机将演示Modelica有效适用于这种系统的仿真。
1. 绪论
一种新产品的设计在开始阶段需要一系列决定,这些决定对最终产品是否成功产生很大的影响。因此,今天在初始阶段使用数字模拟来检验不同的想法。这篇论文的目的是设计一台新的挖掘机并评估几个备选的液压系统。
Multi-Domain Simulation:
Mechanics and Hydraulics of an Excavator Abstract
It is demonstrated how to model and simulate an excavator with Modelica and Dymola by using Modelica libraries for multi-body and for hydraulic systems. The hydraulic system is controlled by a “load sensing” controller. Usually, models containing 3-dimensional mechanical and hydraulic components are difficult to simulate. At hand of the excavator it is shown that Modelica is well suited for such kinds of system simulations.
