Modular load structure assembly having internal strain gaged sensing

摘要

A modular assembly for measuring forces on a structure. The structure may contain a strain gage module that is insertable in a cavity or hole in the structure. There may be numerous structures that can contain a strain gage module. These structures may have various configurations, sizes, and shapes. Despite the various configurations, sizes and shapes, the structures may have cavities or holes of the same size that accept strain gage modules of the same size. Modules of the same size may be easier and less expensive by being produced in multiple quantities, than modules of various sizes. An electronics module may be attached to or separate from the structure. Electronics modules may also be the same items for various structures and be produced in multiple quantities. One example application of the structure may be a strain gage instrumented load pin replacing a standard connecting pin.
