The paper introduces the principle of torsion vibrationsimulator on turbo-generator rotor system, and computes natural characteristics using Riccati matrix.
In this paper, a method of designing a vibrationsimulator based on FPGA, ADC and high-speed DAC is discussed. Hardware block diagram and main FPGA design for this simulator are introduced.
In June, a Crew Module Adapter (CMA) simulator arrived at NASA Glenn's Plum Brook Station for testing, including all-important acoustics and mechanical vibration tests to simulate launch conditions.
