Abstract: In order to more accurately and realistically describe the characteristics of the wind field flow in complex terrain, this paper uses the Reynolds time average (RANS) and large eddy simulation (LES) methods to numerically simulate Bolund island based on the Bolund island experiment results carried out by the Ris laboratory. The study shows that the simulated value of Bolund island is closer to the experimental value at the height of 5 m on the Line B characteristic Line than at the height of 2 m. The simulation results of the pre-island position are more accurate than those of the post-island position. Moreover, LES method can effectively reveal the characteristics of flow around the topography of Bolund island and the vortex characteristics of wake area.

(Lanzhou University of Technology Institute of Electrical and Mechanical Engineering, Lanzhou730050, China)

Abstract: in order to study the effect of cylindrical overflow and circular spillway on the separation performance of hydraulic cyclone, the internal velocity flow field and pressure field were solved by ANSYS software, and the stability of flow field was analyzed. The results show that the tangential velocity is zero on the central axis of the circular spillway hydraulic cyclone, and the outward extension speed is increasing. At the inner wall of the cyclone, the tangential velocity drops to zero, and the tangential velocity of the cylindrical spillway hydraulic cyclone is similar. However, the shear velocity of circular spillway is more stable. The overall pressure drop of the hydrocyclone is 13 kPA greater than that of the hydrocyclone. The separation efficiency and turbulence intensity of the two hydrocyclone are further analyzed It is found that the separation efficiency and turbulence intensity of the round-shaped overflow port are higher than those of the cylindrical overflow port, and the solid-liquid two-phase flow stays longer in the hydrocyclone.

摘要:傳統的自適應洗出算法隨著輸入幅值的增大,其輸出會變得不穩定,從而造成平臺的異常抖動。為了克服這一缺陷,對自適應律提出一種歸一化的修正方案。此方法使得自適應洗出算法中的輸入幅值的大小不會對自適應增益造成影響,進而確保輸出不會因為輸入幅值過大而產生發散,提高動感模擬的真實性及穩定性;而且,改進算法沒有引入額外的懲罰項,因此并未使算法變得更加復雜。經過特定的運動數據進行驗證,結果顯示此方法可以降低輸出發散,減少平臺的異常抖動,提高模擬駕駛的逼真效果。

Adaptive Washout Algorithm Based on Normalization

(1. Jiangsu XCMG Construction Machine Research Institute Co., Ltd., Xuzhou221000, China;

2. Hebei Provincial Key Laboratory of Heavy Machinery Fluid Power Transmission and Control, Yanshan University, Qinhuangdao066004, China)

Abstract:  With the increase of input amplitude, the output of the traditional adaptive washout algorithm appears unstable, resulting in the abnormal jitter of the platform. To overcome this defect, a normalized correction scheme is proposed for the adaptive law. This method makes the adaptive gain independent from the input amplitude, thus ensuring that the output does not diverge with the increase of the input amplitude to improve the authenticity and stability of the motion cueing; moreover, the improved algorithm does not introduce additional penalty terms, so it does not make the algorithm more complex. The improved washout algorithm is tested by using the start-up, uphill-going and braking data of the loader. The results show that this method can reduce the output divergence, reduce the abnormal shaking of the platform, and improve the realistic effect of simulated driving.

Key words: adaptive washout algorithm; normalization; motion cueing; parallel six degree of freedom platform

Study on the Dynamic Characteristics of Cooling Oil in the Hydraulic Cylinder Piston

WANG Xiang

(Yantai Automotive Engineering Career Academy, Yantai265500, China)

Abstract: In order to avoid the failure of sealing ring caused by the high temperature of hydraulic cylinder piston, the two-phase flow model in the cooling cavity is established, and the flow field and heat transfer characteristics in the cavity are simulated and analyzed based on Fluent. The VOF multiphase flow calculation model and SST k-ω turbulence model are selected, and the inlet parameters are defined by UDF method in combination with the piston stroke characteristics. The change rules of liquid phase proportion distribution, oil velocity field and convective heat transfer coefficient at different piston positions are obtained. The results show that the proportion of oil is closely related to the speed, and improving the oil speed is an important means to improve the heat transfer performance. The reliability of the multiphase flow model is high. There is no obvious difference between the average convective heat transfer coefficient obtained by the near wall model method and the wall function method.

Abstract: Aiming at the clamping phenomenon of valve core caused by solid particles in oil, this paper focuses on fitting clearance of sliding valve, in order to explore the influence on the movement of valve core with different particle size. The experimental test was built to measure clamping force along motion of sliding valve. The Euler model of Fluent was used to simulate volume distribution of different particles size in fitting clearance. The results shows that: the particles with different size enter clearance at unilateral size of 0.6 mm, and the clamping force caused by the particles presents pulsating changes. As particle size increases, the clamping force increases. When particle size reaches 70%-90% of clearance size, the clamping force increases rapidly, and the maximum clamping force reaches 19 N. In fitting clearance, solid particles are more distributed in inlet section and less distributed in outlet section, and the larger particle size, the more volume distribution in the clearance.

Study on the Effect of Hydraulic Crushing Hammer on Clamping Force

ZHOU Guang-xing

 (Rocket Force Petty Officer College, Qingzhou262500, China)

Abstract: In this paper, the radial force of the structure at the oil return hole inside the front chamber of the hydraulic hammer is analyzed. Because the piston is subjected to radial unbalanced force in the cavity and the piston reciprocates at high speed, the surface of the piston is damaged. Based on the CFD visualization study and the original model, the large radial force of the original model was verified through the extraction of the front cavity runner. In order to optimize the flow channel structure, two other flow channel models were evolved, and the flow channel models were constructed and digitally simulated. The radial force generated by the optimized flow channel on the piston is greatly reduced, which indicates the direction for the optimization of the structure at the oil hole of hydraulic crushing hammer.

摘要:某企業的萬能軋機功能是軋制高精度鋼軌的重要設備。萬能軋機屬于開式軋機,由傳動側和操作側兩部分機架牌坊組成,更換輥系時兩機架牌坊分離,更換完輥系后兩機架牌坊在軋線上合攏并鎖緊,兩機架牌坊在軋線上合攏并鎖緊是依靠四件預應力拉桿在四個油缸的牽引力作用下實現的。即就是兩機架牌坊分離時四件油缸要釋放牽引力,兩機架牌坊合攏后四件油缸要加上牽引力。在實際的更換輥系中,四件油缸出現了一件油缸只能加上牽引力,不能實現釋放牽引力的故障現象(四件油缸是分別控制的),嚴重影響了萬能軋機的有效作業率。故此,該文著重探討分析了預應力拉桿油缸典型故障原因,從而找到了原因并加以排除解決。
