The utility model has the advantages of simple and practical structure and low manufacture cost, can accurately measure the curved surface total slack water pressure without valuable instruments, and solves the problem that no instrument is used for measuring the curved surface total slack water ...
The value and direction angle of the perpendicularity error of the thrust surface and bearing bush in hydrostatic thrust bearings directly affect the motion accuracy. In this paper, a rapid onsite measurement method and evaluation model for the value and
The aqua planet configuration is used to test cloud changes that are related to increased surface temperatures in order to imitate global warming conditions. Miura et al. ([2005]) compared the cloud cover responses between NICAM and the Model for Interdisciplinary Research on Climate (MIROC) (Hasu...
1 is established on the upper surface of layer 1, the x- and z-axes are respectively along the horizontal array direction and perpendicular to the interface between adjacent layers, while the y-axis is perpendicular to the xz-plane forward. The entire acoustic space can be divided into three...
In the experiment, 35 wave gauges were distributed in the wave flume to measure the actual focusing location of incident waves. Meanwhile, an acoustic Doppler velocimeter (ADV) was located at 0.15 m below the water surface and at the actual focusing location of the incident focused wave groups...
Compared with the smooth surface, the LCC of the structural model is reduced by about 22%. The variation of shear force on the fixed wall and moving wall of the streamwise and transverse microtextures with the dimensionless texture depth is obtained through analysis. Figure 9 shows the ...
The viscous shear force, due to the existence of the velocity difference, converts mechanical energy into heat energy through frictional power consumption. On the one hand, the temperature of the hydraulic oil is increased, and the viscosity is correspondingly reduced, which leads to the change ...
The Stribeck static friction force model was used to identify the friction force; the unmodeled friction force was regarded as an external disturbance. The state equation was used to judge whether the disturbance and the control law were on the same channel. The disturbances were divided into ...
Simulation outcomes indicated the effectiveness of the variable damping sliding mode surface in restraining overshoot and oscillation. Moreover, the optimal value range of the damping ratio was determined. Lastly, we performed an experiment showing the capability of the proposed DV-SMC with double-loop...
