OSCILLATION OF A MATHEMATICAL PENDULUM TAKING INTO ACCOUNT GLOBE ROTATION

Purpose. Development of mathematical pendulum model which considers rotation globe roundit’s own axis and parallel at has been installed with use Lagrange’s differential equations the second kind. Checking whether oscillation plane position respect to a meridian influences model.
 Methods research. Mathematical modelling, kind.
 Results. Two design schemes have developed consider installation place. They differ only by meridian. Formulas for kinetic energy both general formula potential developed. The corresponding nonlinear are received means analysis results show, that period depends not on amplitude but as well test executed, also meridian.
 Scientific novelty. kind, place.
 Practical value.It’s found out, amplitude, meridian, executed oscillation. In particular, it essential value when search minerals is carried out gravimetry using pendular devices, smallest changes gravitational constant estimated.
