If we transform fluid power systems into networks, network theory can be used as a powerful tool for analyzing them. The development of network theory has provided us with many standard and symmetric methods which can be used to establish mathematical models for fluid power systems.

If we transform fluid power systems into networks, network theory can be used as a powerful tool for analyzing them. The development of network theory has provided us with many standard and symmetric methods which can be used to establish mathematical models for fluid power systems. Network methods can, therefore, facilitate the computer analysis of fluid power systems and help to create computer simulations and computer-aided designs.In this article the linear models of the elements of fluid power systems are described. On this base we establish the networks for flow control valves withpressure compensation and two-stage relief valves. The impedance matrix andadmittance matrix for these valves are deduced separately, using the loop method and the node method. Their dynamic character is accordingly analyzed by analytical and numerical method.At the end of this Paper, we introduce a programme which is derived through the above mentioned method. It is used to compute the frequency character of the y-type two-stage relief yalves,

液压系统是由油路构成的网络,它和电路一样,都服从克希霍夫结点定律和回路定律,因而可以用网络理论提供的规范化的方法来建立液压系统的数学模型,以便实现液压系统的计算机辅助分析和计算机辅助设计,使得能够在设计阶段予测系统的最终性能并实现最优化设计。 本文建立了油路元件的线性化模型。在此基础上,构作了调速阀和二级溢流阀的网络图,分别用回路法和结点法建立了它们的阻抗矩阵和导纳矩阵,并对它们的动态特性进行了分析。 在本文的最后,介绍了根据上述方法拟定的一个计算机分析程序,用来计算Y型溢流阀的频率特性。

It has been described in literatures[1] and[2] that the common feature of forced and self-excited vibration encountered in motor vehicle front wheels lies in the fact that a certain amount of energy is fed back via tire-road interaction from the engine to front axle steering system, which may result in the presence of negative damping as in self-excited vibration. Besides tire properties influence the energy input directly and seriously, many other structural modal parameters appreciably influence wheel shimmy....

It has been described in literatures[1] and[2] that the common feature of forced and self-excited vibration encountered in motor vehicle front wheels lies in the fact that a certain amount of energy is fed back via tire-road interaction from the engine to front axle steering system, which may result in the presence of negative damping as in self-excited vibration. Besides tire properties influence the energy input directly and seriously, many other structural modal parameters appreciably influence wheel shimmy. They play the role of energy input control. Literature[2] has investigated the influence of structural modal parameters of frontaxle steering system on vehicle front wheel shimmy.This paper presents the investigation on the influence of vehicle suspended structural system parameters on wheel shimmy. With the complexity of the structural system the simulation becomes difficult and the technique of modal synthesis is necessary. By employing the technique of modal synthesis, a twelfth order mathematical model with five degree-of-freedom is established. A first order torsional mode and a rigid body rotational mode of the suspended structure are counted in the modal synthesis. According to this model, computation for the truck CA-10 and its modified types(tanker truck) was carried out. Computation results agree with experimental results quite well. The difference in the first order torsional modal parameters of suspended structure makes the tanker truck liable to self-excited vibration. The proper selection of the matching first order torsional modal parameters of suspended structure with other parameters of front-axl steering system cn eliminate front wheel shimmy.Elastic modal of the suspended structure being considered in this model, thus all main structural parameters that influence front wheel shimmy apart from alignment angles are taken into account. In such a way we can investigate the influence of many other parameters of structures, including the structures of suspended part, on front wheel shimmy in detail by using the presented mathematical model in the future.

对整车的实验研究表明,整车悬置以上结构模态参数对前轮摆振有重要影响.本文利用了模态分析和模态综合技术建立了十二阶的分析汽车转向轮摆振的数学模型.利用该模型对我国存在前轮摆振问题的CA-10解放牌汽车、以及其变型油罐车进行了仿真计算,计算结果与实车存在的情况相吻合.故此模型可以用于指导前轮摆振的研究工作和有关的设计工作.
