| 摘要减振器的作用就是为了减少车辆震动，降低震动对车辆零件的损害以及提高乘员的舒适性。一般的减振器除了以上作用外，并没有实现对因震动而损失的能量进行回收并加以利用。而这篇论文所讨论的是对一种液电式馈能减振器进行仿真，这种液电式馈能减振器可以对部分振动机械能进行回收利用，实现降低耗能，保护环境的目的。39787 本文所讨论的液电式馈能减振器是对传统减振器在实现减振时热能自然耗散的优化，改变减振器节能性能，使大部分能量得以回收，从而实现能量回收。本文通过简要的汽车悬架介绍，并介绍了减振器的研究发展状况，着重对液电式馈能减振器的描述展开的，了解了其定义、作用和性能要求，并对其进行仿真。 在大量了解了减振器压缩行程和复原行程的工作情况、对减振器油液的特性对减振器的了解以及油液在通过各种阀（包括压缩阀、复原阀、补偿阀、流通阀）的阻尼分析之后，明确其阻尼力的影响因素，发现其容积可变特性、稳压特性、主动可控特性,这便于我们改善系统的性能，发现减振器可能存在的不足与缺陷。根据对液压系统的分析，我们根据减振器独特的结构形式对主活塞的受力分析，利用AMESIM软件进行分析，对液压系统和阻尼特性参数进行选择后，探索并总结了液电馈能式减振器速度-阻尼力关系、示功特性，该结果符合馈能特性。本次课题以汽车节能这个方向出发，众所周知，能源的稀缺是当今社会的首要问题，因此任何对节能的研究都是具有非凡的意义的。这不仅对环境有着十分重要的作用，而且对人们的贡献也很大。 毕业论文关键词:液电馈能减振器、系统仿真、曲线分析。 Abstract The role of the shock absorber is to reduce the vehicle vibration, reduce the vibration damage to the vehicle parts and improve the comfort of the passengers. In addition to the above role of the general shock absorber, and did not achieve the loss of energy due to shock and the energy of the use of recycling. And this thesis discussed is of a hydroelectric power fed to shock absorber is simulated and the liquid and electricity fed to shock absorber can be on the part of the mechanical vibration can recycling, reduce energy consumption and environmental protection. Discussed in this paper, the electro hydraulic feedback type energy absorber is of traditional damping in vibration of natural heat dissipation optimization, change absorber energy performance, making most of the energy is recovered, so as to realize the energy recovery. Through automobile suspension for a brief introduction, and introduces the study and development of shock absorber, focuses on the electro-hydraulic fed to the description of the shock absorber, know the definition, function and performance requirements, and carries on the simulation. In large understand the damper compression stroke and stroke recovery, the characteristics of shock absorber oil understanding of shock absorber and oil through various valves (including damping analysis of the compression valve, a restoring valve, compensation valve, flow valve), clear the influence of the damping force influencing factors found the volume variable characteristic, voltage characteristic, active controllable characteristics. It is convenient for us to improve the system performance, discover deficiencies and problems of shock absorber may exist. According to the analysis of the hydraulic system, we according to the unique structure of the shock absorber of the main piston force analysis, using AMESim software for analysis, hydraulic system and damping parameters of choice, explore and summarize the electrohydraulic feedback type shock absorber damping force, indicator characteristics. The results conform to the characteristics of feed. This subject is based on the direction of automobile energy saving. It is well known that the scarcity of energy is the primary problem in today's society. So any research on energy saving is of great significance. This is not only a very important role in the environment, but also a great contribution to people. (责任编辑：qin) |
