Abstract:  In 1955, Allison released the “C Series” transmission oil specification. The “C Series” specification has been continuously improved, including new and improved tests, test methods, and acceptance criteria. In 2011, Allison stopped using the “C Series” specification and introduced the Allison TES-439 specification. In this paper, the performance change brought by the upgrade of the Allison off-road hydraulic transmission oil specification from C-4 to TES-439 is studied, and the development trend of heavy-duty hydraulic transmission oil performance is discussed.

Abstract:  Taking the fullness coefficients of the valve flap profile line and the shroud profile line in the spool of the axial flow check valve as design variables, the combination optimization design is carried out by using the elliptic cluster method. Eight groups of schemes are obtained by uniform experimental design. In order to improve interpolation accuracy and reliability, eight groups of experimental results are supplemented. After numerical experiments, the optimal combination of fullness coefficients of the valve flap profile line and the shroud profile line is obtained by Biharmonic spline interpolation, and finally, the valve flap profile and the shroud profile with minimum pressure loss are achieved. The results show that the fullness coefficient of the valve flap profile line obtained by Biharmonic spline interpolation is 0.574, and that of the shroud profile line is 0.986. From numerical experiments the theoretical minimum pressure drop is 524.06 Pa and the flow resistance coefficient is 0.26. The minimum pressure drop corresponding to the combination of the valve flap profile line and the shroud profile line is verified by numerical simulation. The simulation result is 525.50 Pa with an error of 0.27%. Compared with the axial flow check valve before optimization, the flow resistance coefficient decreases by 84.97% from 1.73, and the drag reduction is obvious.

摘要： 为研究树脂对丁腈橡胶密封材料的性能研究，利用机械共混法通过添加不同比例的树脂与丁腈橡胶混合制成复合摩擦材料进行拉伸和撕裂试验。采用CFT-I型多功能表面综合测试仪研究在不同转速及不同载荷下其摩擦磨损性能，采用三维形貌仪，SEM分析了在不同转速，不同载荷条件下丁腈橡胶复合材料的摩擦性能。结果表明：添加5份树脂的丁腈橡胶其拉伸及撕裂性能较好，拉伸强度达到10.34 MPa，撕裂强度达到34.75 MPa。但添加过量时，随酚醛树脂用量的增加，拉伸强度和撕裂强度会相应的下降。复合材料中添加5份树脂时，在不同转速下和不同载荷条件下，添加树脂可明显降低其摩擦系数，减小其磨损量。酚醛树脂可以增强丁腈橡胶的基体强度，增大其硬度，增强其耐磨性能。

Abstract:  In order to study the properties of resin on nitrile rubber sealing material, the mechanical blending method was used to make a composite friction material by adding different proportions of resin and nitrile rubber for tensile and tear tests. CFT-I multifunctional surface comprehensive tester was used to study the friction and wear properties under different rotating speeds and loads, and SEM was used to analyze the friction properties of nitrile rubber composites under different rotating speeds and loads. The results showed that the tensile and tearing properties of nitrile butadiene rubber with 5 resin contents were better, the tensile strength reached 10.34 MPa, and the tear strength reached 34.75 MPa. However, the tensile strength and tear strength will decrease with the increase of phenolic resin dosage. When adding 5 pieces of resin to the composite material, the friction coefficient and wear amount can be significantly reduced by adding resin at different rotating speeds and under different loading conditions. Phenolic resin can enhance the strength, hardness and wear resistance of nitrile rubber.

BING Chang-song, ZHANG Yue-yang, FU Yu

(Sino-Italian Taida (Yingkou) Garage Equipment Co., Ltd., Yingkou115000, China)

Abstract:  A practicable hydraulic synchronization system for super low profile alignment scissor lift is introduced. According to the requirements of this kind of the Super Low lift, 6 pieces of the hydraulic cylinders are used. The synchronization of two platforms is guaranteed by double master/slave hydraulic circuits with two assistant cylinder. Automatic oil filling and air bleeding process could be implemented thanks to this specially designed hydraulic cylinder's structure. Two platforms could be synchronized perfectly during every raising and lowering cycle by oil filling or bleeding against the signal given by the sensor so that the cumulated asynchronism could be eliminated. In order to solve the shaking problem during the platforms synchronizing, the throttling structure is added into the hydraulic system. In order to make the front and the rear of the platform are at the exact same level horizontally when the safeties are engaged, a micro limit switch is installed on the mechanical safety rack to detect the signal of safety engagement, thus to stop the master cylinders from moving further.

HE Lei, YUAN Hong-chao

（China Railway Engineering Machinery Research & Design Institute Co., LTD., Wuhan430000, China）

Abstract:  introduce the hydraulic system of front leg of bridge erection machine. When the cylinder stops in operation, there is big vibration and abnormal noise in the pump station high pressure pipe and oil return pipe. When the folding cylinder extends to the end, the system pressure is high and there is instability. By changing the transition function of solenoid directional valve，the vibration and abnormal noise are effectively eliminated. Increase the strength of piston rod, add secondary relief valve to limit the system pressure, which greatly improves the stability of cylinder.

Key words: bridge erecting machine ; solenoid directional valve; transition function; cylinder stability

Abstract:  In view of the traditional hydraulic foot robot foot-type gait walking process, the foot end will be the ground impact, easy to the body impact, resulting in the fuselage is not stable and other issues, a soft control algorithm based on the position inner ring impedance outer ring, effectively reduce the foot end impact, so that the foot end and the ground friendly contact. First, with the hydraulic foot robot single-legged as the object, the robot's single-legged structure and working principle are introduced, secondly, the one-legged hydraulic servo control circuit system is designed, and the hydraulic foot robot components are selected, and finally, the soft control algorithm of the position inner ring impedance outer ring is designed for the soft touch of the foot-walking foot-side touch. The soft touch experiment was carried out using the one-legged experimental platform. The experimental results show that the soft control algorithm based on the position-in-loop impedance outer ring effectively reduces the impact of the foot end, and verifies the design idea and the feasibility of the algorithm application.
