Systems and methods for potted shock isolation

摘要

Systems and methods for potted shock isolation are provided. In once embodiment a shock isolation system comprises an isolator comprising an outer ring for mounting to an external housing, and an inner ring connected to the outer ring via an isolating element; and an inertial sensing assembly comprising: at least one circuit board secured to the inner ring of the isolator, the at least one circuit board further comprising a triad of gyroscopes and a triad of accelerometers; and a low durometer highly dampened supporting material encapsulating a first surface of the at least one circuit board.

1. A method for providing a shock isolation for an inertial measurement unit, the method comprising:
securing at least one circuit board to an inner ring of a shock isolator, the at least one circuit board and shock isolator defining an inertial sensor assembly; and applying a low durometer highly dampened supporting material across a first surface of the at least one circuit board so as to encapsulate electrical components mounted to the first surface within the low durometer highly dampened supporting material; wherein the low durometer highly dampened supporting material forms an external enclosure of the inertial sensor assembly, the low durometer highly dampened supporting material of the external enclosure further encapsulating and potting one or more electrical components mounted to the first surface within the low durometer highly dampened supporting material.
