摘要
应用流体的复势函数理论及缝隙流动理论 ,对具有多供气孔的矩形荷载的气垫场进行了理论分析。用大量的源和汇排列的方法找出了满足边界条件的势函数。从而建立了均匀分布的、任意布孔方式的、多供气孔矩形荷载的气垫压力场压力计算方法和公式 ,编制了计算气垫场任意一点的压力、气垫承载能力 ,压力中心和流量的计算程序 ,并用试验验证了理论分析的正确性。
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.
