A number of scientific and technical experiments were carried out and are s
till being carried out onboard the Mil orbital station in various fields: p
hysics of fluids, space materials study, astrophysics, biotechnology, and s
o on. The duality and reliability of space experiments are essentially depe
ndent on a knowledge of real microgravitational situation onboard a satelli
te, which essentially depends on vibrational perturbations. A lot of vibrat
ion processes studies have been done up to now on the Mir station in the fo
llowing lines of research: control of dynamic and exploitation regimes when
carrying out biotechnological and technological experiments; determination
of the contribution of different onboard systems and mechanisms to the tot
al vibration perturbations power; and investigation of distributions of mic
roacceleratiou levels and dynamics of vibration processes in different modu
les and segments of the orbital station. This paper presents the results of
the analysis of vibration perturbations produced by some standard onboard
Mir station systems in a configuration when the KVANT-2 and KRISTALL module
s were arranged along the yaw axis of the mainframe. It is shown that due t
o strong requirements for tolerable levels of the microaccelerations onboar
d the International Space Station (ISS), the investigations of microgravita
tional situation, as an integral part of the technological environment, now
have a high priority.
