MULTIBEAM ACCELEROMETRE FOR MEASURING ACCELERATION OF PHYSICAL BODY AND ELECTRONIC MODEL OF MULTIBEAM ACCELEROMETRE Russian patent published in 2010 - IPC G01P15/02 A63B23/02 

FIELD: physics.

SUBSTANCE: accelerometre has a mechanical dipole in form of two spaced out masses joined by a rod and not less than six elastic strain-measurement beams which are joined to each other into a multicomponent beam in series such that each of the beams has the greatest sensitivity to one component of force couples caused by three linear and three angular accelerations of the common centre of mass of the physical body. One end of the multicomponent beam is joined to a rigid rod of the mechanical dipole whose axis lies at an angle to the axis of the multicomponent beam, and its second end is attached to the physical body. Each strain-measurement beam has resistance strain gauges combined into a strain bridge. Outputs of the strain bridges are connected to the electronic model of the multibeam accelerometre.

EFFECT: invention enables simultaneous and single-place measurement of three linear and three angular accelerations, which enables to reconstruct the motion path of the common centre of mass of the spine through time integration of the said signals.
