The possibility of simulating lunar microseismic conditions
Abstract
The possibility of simulating lunar microseismic conditions in laboratory testing of seismometers for lunar missions is investigated. The ability of a simple antiseismic filter consisting of a chain of identical masses suspended on inextendable threads to ensure isolation from terrestrial microseisms is considered. The dampening of horizontal and vertical oscillations is analyzed, and peturbations arising from convective air currents and acoustical effects are analyzed. It is shown that an antiseismic filter can be used to simulate lunar microseismic conditions in the one Hz frequency range; placing the filter in a vacuum is unnecessary as acoustical effects are negligible.
