(大连理工大学机械工程学院,辽宁 大连  116024

   要:土力学试验中的三轴试验仪,能够测量土壤的强度、应力应变及其它力学性能等,是研究土壤特性极其重要的设备。土壤试样在大围压、重载荷下获得的排水量是衡量试样体变的一个重要参数,它的测量精度决定试验的成败。然而对于超大试样体变(排水量)的测量,由于排水量大、排水时间长等特点,对其连续高精度测量是非常困难的。该文提出了一种超大试样体变(排水量)实时连续高精度检测方案,利用自带的12ADC模块的ARM微处理器STM32F103ZET6对注入AB量筒内的排水进行连续模数转换和数据处理,根据AB量筒内注水液面的高度,控制多个电磁阀动作,实现AB量筒交替注水/排水。利用LABVIEW作为上位机通过RS-232串口控制整个检测过程,显示并存储两通道的采集结果。最后对该方案进行了试验验证,试验结果表明,该方案稳定性好,测量精度高,可以实现对超大试样体变(排水量)连续高精度检测。

(School of Mechanical Engineering, Dalian University of Technology,

Dalian 116024, China)

AbstractThe tri-axial test apparatus in soil mechanics test can measure the strength of the soil, the stress strain and other mechanical properties. It is a very important equipment for the study of soil properties. Water drainage obtained from soil samples compressed by high confined pressure and heavy load is a key measurement index of specimen deformation. The measurement precision on water drainage determines the success of the test. However, it is very difficult to achieve the continuous and high accuracy measurement for the large sample volume change (water drainage) due to the large amount of drainage and a long drainage time. This paper proposes a solution to achieve high-precision continuous measurement for the large sample volume change (water drainage). ARM microprocessor STM32F103ZET6 which owns 12 bit ADC module is used to do continuously analog-digital conversion and data processing for water drainage injected into A, B graduated cylinder. According to the situation of how much water A, B graduated cylinder are filled. The electromagnetic valves are controlled to achieve A, B graduated cylinder alternately filling/drainage. LABVIEW is used as a upper computer to control the entire testing process, display and store two channels results. According to result from experimental verification, this solution shows higher measurement accuracy, stronger stability and can achieve high-precision continuous measurement for the large sample volume change (water drainage).

AbstractTwo symmetrical actuators hydraulic system being synchronously controlled by single pump could be realized with axial piston pump with four distribition windows, which could also directly controlled differential cylinder in a closed-loop way. The pressure and flow characteristics were analyzed based on the single piston motion characteristics and the change of assignment area. SimulationX software was applied in the modeling and simulation analysis of axial piston pump with four distribition windows. The hydraulic pump output flow was adjusted by setting the swash plate angle or cylinder speed. Taking the oil leaks and viscous friction into consideration, the characteristic response curve of plunger cavity, oil-pumping port pressure and flow has been analyzed under the condition of load and no-load. The simulation results show that the flow pulsation frequency increases with increasing pump speed; the pressure pulsation amplitude increases as the load increases, and the pressure pulsation frequency is independent of the load.

AbstractThe two cylinders with the synchronization machine of gears and racks were used to make the carriage stretch and withdraw. Compared with the shape of two electric handspikes, this form advanced the synchronization performance. For improving the intelligent and abide errors abilities, the button, remote device and Pad all could be used to manipulate it. Furthermore, if the pressure exceeded the limit, the system will stop automatically to protect the motor. The electric-hydraulic system controller (EPEC 2024) was connected with the centralized control system of the vehicle, so the pad could detect electric-hydraulic states conveniently. The complexity was decreased and the automatic degree was increased.

AbstractThe butadiene isoprene copolymers (BIRs) were synthesized by n-Butyllithium (n-BuLi)  tetrahydrofuran (THF)  Cyclohexane (Cy) initiator system. The hydrogenated butadiene isoprene copolymers (HBIRs) were obtained by catalytic hydrogenation of the BIRs proceeded by Nickel 2-ethylhexanoate  triethyl aluminum. The molecular weights and molecular weight distributions of the polymers were characterized by gel permeation chromatography (GPC), and the microstructures of the polymers were determined by 1H-NMR, and the thermostabilities were measured by thermo gravimetric analysis (TGA). The HBIRs were  dissolved in 150SN base oil, and effects of the microstructures and the molecular weights on the performance including the thickening abilities, the shear stabilities, and the low temperature start abilities were investigated, and the compatibilities with pour point depressant were studied. Several low temperature hydraulic oils with different viscosity grade were formulated using HBIR as viscosity index improver. HBIRs could improve the viscosity index of the oils drastically, but had no effect on pour point.

AbstractThe chamfering radius of sealing groove mouth could avoid scratching by sharp edges during installation and using , But  the selection of the chamfering radius mostly based on experience. It is found that the chamfering radius has important effect on sealing performance in practice using. In the paper, the O-ring of 18 x 1.8 under GB/T3452.1-2005 is selected, in the case of other parameters constant, using ABAQUS to analyze the effect of chamfering radius on Von Mises stress and contact stress of O-ring when the medium pressure change from 2.5MPa to 16MPa. The analysis shows that the chamfering radius changes from 0.1 to 0.5, the effect of chamfer is not obvious on sealing performance under small medium pressure, but the maximum Von Mises stress increases about 43% when the high medium pressure, and the volume squeezed into seal clearance increased, the maximum contact pressure points moved to the groove mouth, which has obvious effect on sealing performance.

AbstractThe driver for the impellers of a blower is operated at a high speed by a 25-gear shaft in accessory machine. Hence, it forms the inside-outer diameters channels. The blower drive is encapsulated by magnetic sealing device from outside and an O-ring from inside. Affected by vibrations, shifts, specific pressure, frictional heat and other factors, the lubrication leakage and the blower drive sealing device often breaks down while working at high speed. Thus, this paper analyzes the problems employing the method of complete switching installation. This paper aims to explore the relations between the improvement of the assembly accuracy and the precision of manufacturing. It is believed that adopting improved methods to control assembling can contribute to the precision of manufacturing. This is of important significance for eliminating leaking problems.
