Mathematical Model of a Testbed for Accelerometer Trials

Abstract

We develop a mathematical model of a dynamical testbed for testing accelerometer assemblies created at the Keldysh Institute of Applied Mathematics. It has a movable platform with one degree of freedom. It can rotate about the axis fixed in the prescribed direction. The tested accelerometer assemblies are placed in the platform that rotates arbitrarily. Its real motion is reconstructed a posteriori by measurements of the vision system. The reconstruction is carried out in digital form and allows us to calculate the real acceleration felt by the assemblies. The calculated acceleration is compared with the measured one. The comparison results are used to test and calibrate sensors, electronic units, etc.
