AbstractThe hydraulic pulsation active control technology is widely studied because of its strong adaptive ability and good attenuation effect. In the current study has not yet the active control method of inflow small flow oil into pipeline to offset the pressure pulsation of the trough value. This paper took the lead in the research on the active control of the flow pulsation with inflow method, and carried out the theory and simulation. And the model of piezoelectric direct drive throttle valve was also built in this paper. In the control algorithm, due to the nonlinear characteristics of the actual system, the BP neural network algorithm was used to adjust the parameters of the controller, to make the piezoelectric throttle valve generate the secondary pulsation, while the secondary pulsation and the initial pulsation in the pipeline were mutually offset to achieve the best effect of pulse attenuation. The results show that the active control of the flow pulsation with inflow method based on neural network can reach 67% of the pulse suppression effect.

AbstractRelief valve is one of the most important components to guarantee construction machinerys stabilization. Noise and vibration exist in the relief valve that nears the main pump outlets during the mechanical operation process of the loader. To solve this problem, the direct relief valve with level 2 pressure regulating sets the secondary damping hole, uses double spring system, and sets up a damping hole between the spring chamber and the oil outlet. The thesis analyses its static characteristics and dynamic characteristics by mathematical modeling. Doing some simulation in AMESim, the parameter is analyzed, the model correctness is verified. Better precision regulatorlarger range of pressure and faster response speed than ordinary relief valve is showed in the improved one in the simulation results. At the same time, it prevents valve cores and valve seats from colliding, reduces the failure rate, and decreases pre-compression spring value to improve the spring life. The aim is to provide assistance to the study and design of the relief valve.

   要:当前传统液压挖掘机在一次工作循环中,回转过程的能量消耗约占总能量消耗的25%40%,其中回转动能很大一部分都通过溢流阀损失,最终以热能的形式而散发掉。为此,该文基于二次调节技术构建液压挖掘机回转系统,利用仿真软件AMESim建立了整个系统的仿真模型,并根据液压挖掘机回转90度的典型工况,进行挖掘机回转制动能量回收效率的节能仿真研究,结果表明:系统总的制动能量回收效率可达到[η]=62.4%,在相同的工况下比普通液压挖掘机节能24.7%。与此同时,该文应用该仿真模型,对影响能量回收效率的因素进行定性研究,结果表明:随着转动惯量的增大或系统压力提高,能量回收效率[η]及节能效率[ηs]均增大;而随着蓄能器容积的增大,能量回收效率[η]几乎不变,节能效率[ηs]明显减小。

Swing System Based on Secondary Regulation Technology

WEI Peng-bin, ZHANG Hong, GUO Kai, SHI Jian-wei, MA Meng-qi

School of Mechanical Engineering, Dalian University of Technology, Dalian 116024,China

AbstractThe energy loss during rotation accounts for 25%-40% of the total energy consumption of conventional hydraulic excavator in a working cycle, and most rotary kinetic energy loses through the relief valve, finally dissipating in the form of heat. This paper builds a hydraulic excavator swing system based on secondary regulation technology and establishes the simulation model of the whole system via simulation software AMESim. Additionally, based on a typical working condition that the hydraulic excavator slews 90 degrees, the energy-saving simulation of excavator slewing brake energy recovery efficiency is investigated. The results show that the total brake energy recovery efficiency of system can reach 62.4%,and that the hydraulic excavator with secondary regulation technology can save 24.7% more energy compared with ordinary hydraulic excavator under the same working condition. Influence factors of energy recovery efficiency are also investigated. According to the results, energy recovery efficiency [η] and energy-saving efficiency [ηs] increase with the increment of rotational inertia or system pressure; while increase of the accumulator volume results in an almost unchanged energy recovery efficiency [η] and an obviously decreased energy saving efficiency [ηs].

Finite Element Analysis of the Detachable Lip Seal Separating Speed

Xian Aerospace Propulsion Institute , Xian  710100, China

AbstractThis paper presents the research of the separating rotate speed of the lip seal with high rotation using the finite element method The results of rotate test of the lip seal with water are in good agreement with the finite element simulations. The calculation indicates that the centrifugal load of the spring slightly affect the separating rotate speed . When the pressure gap from foreside to rear end is invariability, the separating rotate speed increases with reducing the middle thickness of the lip seal. When the structure is invariability, the separating rotate speed increases with the pressure gap increaseing. To compare with the thickness of the lip seal, the pressure gap has a strongly effect on the separating rotate speed.
