Circular plate deflection under effect of a gas pressure fixed along a parameter and having random number of supports

A study was made on dependence of deflection of a circular plate, fixed along a perimeter, on location of point supports on deformed surface under gas pressure. Plate deflection is presented in analytical and diagram form, enabling to find the result more quickly. Such problems occur when designing some electrophysical facilities and cyclotrons in particular. The use of a large member of plates is necessary in order to decrease plate deflection under the effect of gas pressure. 8 figs
