随着对车辆性能要求的不断提升，广泛用于半主动悬架的阻尼可调液压减振器由于结构简单可靠、性能稳定、能耗低且性价比高成为关注热点。然而，当前该类减振器的精准模型及调节机理缺失、阻尼力输出失准成为制约其研究及应用的瓶颈。本课题中以阀控式阻尼可调液压减振器为对象，探究结构动力学引起的流体动力学不平衡状态，进而分析其引起的气液多相形态对压力响应及管路瞬态效应的影响，并在热耗散基础上实现基于先进人工智能算法的阻尼力温度补偿方法的研究。具体内容包括：阻尼可调液压减振器阀口阻尼特性的定义及其调节机理的建立；气泡与气穴在产生、共存及消亡的动态更迭机理及其对阻尼力波动及延迟的影响；热力学效应下减振器热耗散模式的分析及阻尼力温度补偿体系的建立。项目以揭示结构-流体耦合系统建模方法与调节机理、多室内腔的气-液-热状态分析为目标，最终实现阀控式阻尼可调减振器阻尼特性理论的建立及其补偿系统的工程实践。

With the increasing demand of the vehicle performance, the adjustable hydraulic shock absorber (AHSA) has attracted public attentions and has been widely employed in the semi-active suspension system due to its superiorities of simple and reliable structure, stable performance, low energy consumption and cost efficiency. However, the absence of the explicit model and regulating mechanism, and the inaccurate output of the damping force become the bottleneck of AHSA in terms of research and practical applications. Taking a valve controller AHSA as the object, this project investigates the imbalance status of the fluid dynamics caused by structural dynamics, and then studies the influence of the multiphase morphology of the gas-liquid on pressure response and transient effect of the pipe. Subsequently, based on the heat dissipation mechanism, investigations on temperature compensation system of the damping force with advanced artificial intelligent methods have also been conducted. The detailed contents of this project include: Definition of the damping characteristics of the AHSA valve and the establishment of its regulating mechanism; Dynamic mechanism of the bubble and cavitation in terms of generations, coexisting and extinction and their impacts on the fluctuation and delay of the damping force; Analysis of the heat transfer modes of the AHSA under thermodynamics and the construction of the temperature compensation system for the damping force. This project aims to reveal the modeling methods of structure-fluid coupling system and its regulating mechanism, as well as the analysis of gas-fluid-heat status under multi-interior cavity, and finally achieving the theoretical construction of the damping characteristics and the engineering application of the compensation system of the valve controlled AHSA.
