INERTIAL MEASURING UNIT WITH REDUCED SENSITIVITY TO THERMOMECHANICAL CONSTRAINTS

摘要

A measurement unit comprising at least two elements, namely a block and an inertial sensor, a first of the elements being provided with studs, each having a surface against which a bearing surface of a second of the elements is applied under a force substantially normal to said surfaces, which force is exerted by at least one clamping element, the studs being of dimensions and shape adapted:to allow the studs to deform under the effect of a thermomechanical stress occurring in an operating temperature range of the measurement unit so as to avoid any slip of said surfaces relative to one another under the effect of that stress; andto keep the inertial sensor in position while ensuring that any transmission of vibration is limited and compatible with the operation of the sensor.
