Document Type and Number:
Japanese Patent JPH0810149
Kind Code:
B2
Abstract:
Most prior mounting systems for accelerometers have been noncompliant and have therefore resulted in stress being applied to the transducer due to differential thermal expansion. This limitation is overcome by the mounting system of the present invention that is adapted to support a precision transducer (14) in spaced alignment with a supporting case (12). The mounting system comprises a plurality of mounting elements (30), each mounting element having a first end (34), a second end (32) and a resilient intermediate portion (36). The first end is connected to the transducer, and the second end is connected to the case. The first ends of adjacent mounting elements are preferably joined to one another by bridge sections (38) to form a continuous mounting ring (16), and the second ends of adjacent mounting elements are preferably separated by gaps (56). At least the first ends and bridge sections are composed of a substance that has a coefficient of thermal expansion approximately equal to the coefficient of thermal expansion of the transducer. Each intermediate portion is adapted to provide a low resistance to relative movement between the transducer and case in a radial direction, and a high resistance to relative movement in other directions. The mounting system therefore securely mounts the transducer against rotation and overall translation, while being compliant with respect to differential thermal expansion.
