MNOGOBALOCHNY accelerometer to measure the acceleration of the physical body and an electronic model MNOGOBALOCHNOGO ACCELEROMETER

摘要

The invention relates to measuring equipment for conversion into electrical signals accelerations. The device can be applied in orthopedics as a control position of the spine in three-dimensional space of motion by measuring the 3-line and 3-angular accelerations common center of mass (GCM) of the patient's body. They solve the following technical problem - measuring simultaneously and a single 3 and a linear 3-angular accelerations. Having this information into electrical signals by allowing the integration over time of the signal path to restore spinal movement OCM. amount of elastic tenzometrirovannyh beams To solve this technical problem, the mnogobalochnom accelerometer for measuring accelerations of a physical body, containing more than one elastic tenzometrirovannoy beams and mechanical dipole in the form of two interconnected rod spaced masses, at least six, they are interconnected in a multicomponent beam sequentially so that each of the beams has the greatest sensitivity to a component force couple induced by three linear and three angular accelerations ma common center ss physical body, with one end of a multicomponent beam is connected to the formed rigid rod mechanical dipole whose axis is at an angle to the axis of the multi-component beam and the second end of a multicomponent beam is fixed on a physical body, while each tenzometrirovannaya beam comprises a strain gage integrated in tenzomost, and outputs tenzomostov connected to an electronic model mnogobalochnogo accelerometer.
