Identification Random Wind Pressure at Non-uniformly Distributed Pressure Taps with Proper Orthogonal Decomposition Method

The proper orthogonal decomposition(POD) technique was applied to identification random wind pressure time or frequency domain specific property.The wind pressure taps was always non-uniformly distributed on the complex structure.Thus,a POD procedure appropriate for a case of pressure specified at non-uniformly distributed taps by considered the weight of taps area.The dynamic response structure was analyzed in time or frequency domain by using the wind pressure data.At last,the results of random wind pressure low-dimensional power spectrum showed that the weighted POD approach was effective;the wind pressures at many locations on the structure were measured simultaneously in a wind tunnel.
