INERTIAL MEASURING DEVICE WITH REDUCED SENSITIVITY TO THERMOMECHANICAL STRESSES Russian patent published in 2022 - IPC G01C19/5783 

FIELD: measuring equipment.

SUBSTANCE: invention relates to an inertial measuring device containing two elements: a block of sensors and an inertial sensor, wherein the first of the specified elements is equipped with racks, each of which has a surface, to which a support surface of the second of the specified elements is adjacent, pressed by a force essentially perpendicular to the specified surfaces, wherein the specified force is created by one attachment element, wherein the specified racks have such a shape and such dimensions so that to provide a possibility of deformation of racks under the action of thermomechanical stress occurring in an operating range of temperatures of the measuring device, so that to avoid any slip of the specified surfaces relatively to each other under the action of this stress; and to provide retention of the sensor in a required position, providing only limited transmission of vibration and compatibility with sensor operation.

EFFECT: creation of a means for limitation of impact of a temperature on operating characteristics of an inertial measuring unit.
