Design and Simulation of Cam Pressurized CVT by Hao Jianjun, Liu Yunyun, Lan Jiashui, Xiong Feng

“…Aiming at the problems of the current CVT actuated by hydraulic control system,such as high energy consumption,complicated control systems,speed ratio and transmission ability being limited by metal belt axial deflection,a new designed cam pressurized CVT hydraulic system is proposed,which is composed of cam automatic pressurized device and closed hydraulic system.The cam pressurized device automatically provides most of the clamping force,the closed hydraulic control system provides the auxiliary clamping force and changes the speed ratio.The new designed hydraulic control system with simple-structure can leave out expensive reversing values and reduce overflow loss,therefore it has advantages of less component parts,energy conservation,environmental protection and low cost.The structure design and working principle of the CVT system are introduced,and the simulation analysis is carried out by using the Matlab/Simulink software.The simulation results show that the cam pressurized CVT hydraulic control system has the significant advantages of fast dynamic response,stable performance and so on.…”

Experimental Study of Awash Soil under Static and Cyclic Shear Loading by Tigistu Abu Arficho, Argaw Asha Ashango

“…Cyclic simple shear tests were conducted to study the variation of shear modulus and damping ratio with a different number of factors for strain amplitudes of 0.01%, 0.1%, 1%, 2.5%, and 5% and for a frequency of 1 Hz at an axial stress of 150 kPa, 275 kPa, and 400 kPa. The result shows that the damping ratio decreases with an increase in confining pressure at different cyclic shear strains. …”

Peristaltic Transport of a Particle–Fluid Suspension through a Uniform and Non-Uniform Annulus by K. S. Mekheimer, Y. Abd Elmaboud

“…The inner tube is uniform, rigid and moving with a constant velocity V0, whereas the outer non-uniform tube has a sinusoidal wave travelling down its wall. The axial velocity of the fluid phase uf, particulate phase up and the pressure gradients have been obtained in terms of the dimensionless flow rate Q, the amplitude ratio ɸ, particle concentration C, the velocity constant V0 and the radius ratio ϵ (the ratio between the radius of the inner tube and the radius of the outer one at the inlet). …”

A Mathematical Model for Peristaltic Transport of Micro-Polar Fluids by S. K. Pandey, Dharmendra Tripathi

“…A mathematical model has been constructed for peristaltic transport of micro-polar fluid in a circular cylindrical tube of finite length by letting sinusoidal waves propagate along the wall that induce contraction and relaxation but not expansion beyond the natural boundary. Axial and radial velocities and micro-rotation components are formulated for micro-polar fluid transportations by applying the method of long wavelength and low Reynolds number approximations in the analysis. …”
