Abstract	The objective of this study was to quantify the dynamic response of the living grass-like crops structure under free and forced vibration. The living grass-like crops may become the key component in a new technology which extract and make use of unwanted energy associated with structural vibration. The proposed procedure is firstly illustrated with a simulated example of the simple pendulum configuration with the tray holding the grass. Output of the vibrating grass is measured through frequency analyzer (FFT Analyzer). The relative decay of the amplitude of vibration is used to measure the damping effect of grass. Secondly, forced vibration effect is studied by designing the slider crank mechanism over a frequency range from 0.7 to 1.7Hz. Resonant effect is studied. The difference in the acceleration, velocity, and displacement between the vibration tray loaded with the crop and the tray without the crop for the same power input will measure the vibration suppression capabilities of grass-like crops. The result of the experiments quantifies this damping effect and extrapolates the data to estimate the effects of a crop-based life support system on a spacecraft.
