Modeling and Dynamic Characteristic of a Pneumatic Solenoid Valve Xiaowang Pan, Min Lin, Bin Guo and Yi Lu College of Metrology and Measurement Engineering, China Jiliang University Hangzhou, China linm@cjlu.edu.cn Keywords: Pneumatic Solenoid Valve, Mathematical Models, Air Model Abstract.
Great attention was paid to the fact that all parameters have a physical meaning and therefore can be measured directly or can be obtained from material data sheets.
The spring pretightening force is the key factor to accelerate the open, but it could not exceed a limit [2].

To ensure the grinding quality as well as the grinding efficiency for SiC wheel grinding of Si3N4, grinding parameters are proved to be a key factor.
Under a certain material removal rate, the results of prediction of both ground silicon nitride surface roughness and surface damage can be acquired by using the approaches presented above.

This experiment chooses the steel tube, its diameter is 48×3.5mm, but the steel tube’s diameter is 48×3.21mm in the actual measurement, experimental materials buys from manufacturers configuration, the fastener’s dead load is 10.2~11.1N.
Test model parameters’ set and fittings materials’ selection refer to the actual status of the construction site.
Using ANSYS makes the finite element analysis of template stents, because fastener tubular steel template stent takes the tube whose diameter is 48×3.5mm as the main supporting material, the text chooses the pipe 20 as the element.

Bearing lifetime is running time of the bearing until the appearance of signs of material fatigue on the contact surfaces of solids of revolution or the races [4].
The rotor design is the key to the operation of the open-ended spinners.

Evolution of Recrystallization Textures in Cold-Rolled Commercially Pure Aluminum Dong Nyung Lee1,a * 1Department of Materials Science and Engineering, and RIAM, Seoul National University, Gwanak-ro 1, Seoul 08826, Republic of Korea adnlee@snu.ac.kr Keywords: Aluminum, Cold-rolling, Recrystallization, Texture, Strain-energy-release-maximization Abstract.
At this stage the material contained plate-shaped intermetallic FeAl3 particles having the diameter to thickness ratio in the range 1-8.
The texture of the starting material was relatively weak, with {001}<100> and {110}<001> as the dominant texture components [1].
The starting material was cold rolled by 90% reduction in thickness, and circular discs of 15 mm in diameter were stamped out.
