In theory,for the five models of electronic safety and arming(ESA),the highest degree of safety is attained through control with three electronic switches added by two time windows closed simultaneously.
The leverage of synchronously closing machine is important for multilayer hot-press in forestry industry because its closing precision directly affects product's quality.
Neutral magnetic field was found wide important applications in space physics and satrophysics[1-4].In a rectangular coordinate system x y and z,the neutral magnetic field is,given by Eq.(2-1),where h is a small northward magnetic field[5],a and e are the parameters of the field.When ε=0 the field is a neutral sheet.An analytical trajectory of the charged particle moving in this field has been calculated The results are:(1)By means of a perturbation method[5],we found that the motion of the charged particle...
In the designing of the simultaneous closing device of hot press model BY, the design methods and structure options of hydraulic cylinder compensator were discussed, and the value of compensation was calculated. The result proves that it is possible to make full use of hydraulic accumulator of rapid simultaneous closing and to reduce the overall dimensions of the device. On the basis of theoretical analysis, hydraulic circuits under various conditions were presented.
