Modeling and model reduction of the luffing system for boom-type aerial work platforms
摘要
Abstract
This study focuses on the boom luffing hydraulic system of boom-type aerial work platforms.A hydraulic simulation model is developed using AMESim software,and its accuracy is verified through mechanical-hydraulic co-simulation.To optimize the model for real-time simulation,a linear frequency domain analysis method,supplemented by active energy index analysis,is used to simplify and reduce the model's order.Components with higher natural frequencies and lower activity indices are either removed or modified,and parameters of certain high-frequency models that could not be removed are adjusted to achieve real-time simulation compatibility.The reduced-order hydraulic system model significantly reduces computational time while maintaining a high level of fidelity,meeting real-time simulation requirements effectively.关键词
