推导压力容腔的新公式

  钰,邹炳燕

(天津中德应用技术大学  航空航天与汽车学院,天津  300350

   要:现存的压力容腔公式描述的是压力增量、压缩的体积、初始体积和体积弹性模量之间的关系,但是随着压力的增加,气体或液体的体积弹性模量也是增加的,这样就找不到压力增量与体积变化之间一一对应的关系了。如果按照低压状态下,体积弹性模量的数值计算,压力增量则会比实际值偏小;因此该文通过重新定义体积弹性模量,来保证压力在逐渐变化的情况下,压力增量与体积变化之间仍然存在一一对应的关系;并根据该体积弹性模量定义,推导了压力容腔的新公式;又通过实验,验证了新的压力容腔公式的准确性。新公式虽然只经过气体验证,但同样适用于液体。它为计算液压系统的压力动态响应问题提供了新的理论依据。

Deduce New Pressure Chamber Formula

HAN YuZOU Bing-yan

TianJin Sino-German Vocational Technical CollegeTianjin 300350China

AbstractThe original pressure chamber formula describe the relationship, which between pressure changecompressed volume original volume and bulk modulus. However, the bulk modulus value will increase as the pressure goes up, it is impossible to find the one-to-one correspondence relationship between pressure change and volume change. The pressure change value will be smaller than the actual value if calculating with bulk modulus in low pressure. So in order to find one-to-one correspondence between pressure change and volume change even if the pressure goes up, the bulk modulus will be redefined in this paper. And according to the new bulk modulus definition, the new pressure chamber formula is redefined, then the new formula is verified to be credible by means of experiment. Though the new formula is tested by the experiment via the air equipment, it also can be applied in hydraulic system. It provides the new theory evidence when calculating the pressure dynamic problem in the hydraulic system.

AbstractIn order to address the problems of the traditional servo valve like the complex structure, the expensive cost, and the low upper frequency, a new rotary high speed four-way reversing valve with dual-spool and two degrees of freedom is designed. The flow characteristics of this valve are studied by Computational Fluid Dynamics. In addition, based on the rotation angle, the characteristics of the pressure and velocity distribution under static and dynamic condition is analyzed, and the analysis results under static condition is compared to the results under dynamic condition. The research results prove that the pressure loss of the rotary valve are concentrated in the contact parts between axial channel of the left spool and axial channel of the intermediate shaft. Meanwhile, as the angle increases, the pressure loss of the contact parts and the low pressure regions are reduced gradually. What is more, as the angle increases, the velocity of the contact parts  is changed slightly and the average velocity is increased.

AbstractDesign of the power stage spool is generally the beginning part of servovalves design. The structural parameters of the spool valve are determined on the basis of the flow saturation design theory, and then the structural parameters of the pilot stage are determined. The spool flow saturation coefficient regulated in the existing design theory should not be less than 4, but it’s found that the regulated coefficient is high for practice and fails to be optimized. By means of analysis, modeling, calculation and verification in practice, the effective value of flow saturation coefficient is confirmed, and accordingly the servovalve flow saturation design theory has been revised so as to provide theoretical basis for similar research activities, shorten the R & D cycle and reduce R & D expenses.

  要:液压传动是现代工程机械中广泛应用的一种传动方式,而液压缸是液压传动系统中最重要的执行元件之一。当液压缸承受较大的载荷做高速运动至行程末端时,往往会产生剧烈的机械碰撞,从而产生很大的机械冲击与振动,为防止或减轻这种机械冲击与振动,一般采用缓冲装置,可在一定程度上起到缓冲作用。该文首先对工程机械液压缸采用缓冲装置的原因进行阐述,重点讨论缓冲原理与常用缓冲形式,并对其进行对比分析,为液压缸缓冲装置的设计与选型提供一定的参考意见。

AbstractWe design an alarm device for mountain bike lock, which is based on hydraulic force transmitting device. The device is refitted by combining brake lever, brake pad and lock device, and connected with T-Cock. When we press the operation bar, both ends will press the bar of sliding block and make it turn round under a circular motion. The other end of sliding block is spliced with the bar of pressing oil, in order to oppress the oil pipeline. In combination with the warning device, the bicycle is locked. At the same time, when the vehicle is subjected to vibration, the alarm is turned on. The purpose of double protection is achieved. This kind of device not only protects the mountain bicycle in a better way, but also improves the efficiency of locking. Most importantly, it can reduce the probability of bike theft.
