Abstract

The invention belongs to the technical field of helicopter model rotor testing, and relates to a special base rotating table for a phase Doppler particle analyzer. The base rotating table comprises alinear motion platform mechanism and a rotary motion platform mechanism, wherein the linear motion platform mechanism is fixedly connected with the rotary motion platform mechanism; and a screw rod isarranged in the linear motion platform mechanism, and a gear pair is arranged on the rotary motion platform mechanism. The rotating table has linear motion and axis around rotation functions at the same time, so that finally the special base rotating table of the phase Doppler particle analyzer can complete linear motion and rotary motion functions, and the requirement of wide-range measurement of the phase Doppler particle analyzer can be met.

Description

technical field [0001] The invention belongs to the technical field of helicopter model rotor tests, and relates to a base turntable of a phase Doppler particle analyzer. Background technique [0002] With the continuous development of rotor model test technology, the phase Doppler particle analyzer is also constantly developed to meet the measurement requirements during the test. At present, there are mainly two forms of phase Doppler particle analyzers. One is fixed position measurement, which can only measure fixed areas; the other is mobile measurement using a mobile platform, which can measure large areas within the moving range. . [0003] At present, the mobile platform used by the phase Doppler particle analyzer can only realize linear displacement movement, and the moving distance is short, and it cannot realize rotational movement, which limits the measurement range and efficiency of the phase Doppler particle analyzer and reduces the phase Versatility of Doppler...
