rudder deviation motion be smooth without blocking, the waveform be not distorted, and the phase shift be within a certain range. At the same time, the polarity
of loading can be changed, the assistant moment can be generated to simulate the
counter-maneuvering state, and the anti-counter maneuvering ability of rudder
system can be tested by using the parameters of ballistic characteristic points at
subsonic and transonic speeds. It should satisfy all the requirements of the loop
characteristics of control system.
(3) Vibration Modal Characteristic Test of Control Execution System
The rudder control system and the missile-borne hydraulic energy are in the working
state. The steering surface is clamped at zero position by the input return-to-zero
signal of the integrated amplifier. The wideband electromagnetic exciter is used to
excite the rudder surface. The displacement or velocity of each characteristic point
on the rudder surface is measured by a precise sensor. The natural frequencies and
modes of the rudder surface are obtained, and the torsion-bending frequency ratio is
determined, which provides a basis for the analysis of rudder control flutter. At the
same time, the frequency response characteristics of high-speed rotating components
of missile-borne energy, such as turbines, generators, and hydraulic pumps, can be
measured by vibration spectrum analysis.
