Abstract:
The air
cushion field’s pressured rectangular pad with multiple supply holes are
analyzed theoretically by use of complex potential theory and slit flow
theory. An appropriate potential function, which satisfies the boundary
condition is found by using arrays of infinite sources and sinks. Then
calculation formulas of this air cushion field’s pressure distribution
with any evenly distributed air-supply holes are derived. A calculating
program is worked out and theories mentioned are proved to be correct by
tests.
Key words:
Air
cushion field’s pressure Complex potential function
Air-supply holes Load capacity flow
