double plate
1.Digital simulation and CAD program of force feedback electrohydraulic servo valve with double nozzle-plate
3.The paper describes the arrangement characteristics of feed plate androller for C4 card, calculates and contracts some technological parameters,deducting the formulas of carding parametric length, distance between holdingand initial carding points, as well as the distance between the feed plate noseand the surface of licker-in respectively. Then the double are plate cardingfunction and some problems about straight forward feed are discussed.
8.Design of Electric Control System of Double-action Paper Plate Punch YB28-630A
9.It produces 15,000 tons high-quality paper, mainly double-faced offset plate paper, offset book paper, art printing paper, poker paper, computer printing paper, electrostatic duplicating paper and so on.
10.With the help of nonlinear finite element software ADINA, the distribution pattern and magnitude of back earth pressure of the anchor slab retaining wall with double layered anchor plate with various material parameters were analyzed, and the factors influencing the earth pressure ware discussed, also.
