7 Fatigue Rated Universal Flat Load Cells The best features required by fatigue applications are provided for in the structure of the Strainsert Flat Load Cell. The structure of the Flat Load Cell is simple and compact, consisting of an inner loading hub and an outer supporting flange bridged smoothly by a uniformly continuous solid shear web. Strainsert gages are installed and sealed inside small gage holes along the neutral axis of the web. Structural stress raisers are avoided. The lowest deflection and highest natural frequency of any available load cell are thus obtained, along with the highest resistance to extraneous forces. Mechanical and Dynamic Properties of Flat Load Cells are fully tabulated. In all other similar, Low Profile Load Cells the shear web is cut up into so many spokes, not because a most efficient structure would require it, but to provide a manageable arrangement for the installation of shear gages on external surfaces, which then have to be sealed and protected by suitable covers. Both the shear web cutouts and sealing covers are undesirable sources of fatigue failures, avoided in the Flat Load Cell. Long fatigue life (10 9 cycles) and stability of the Flat Load Cell is mainly due to low strain levels Universal Flat Load Cell the shear gages are subjected to: ±500µe FS for completely reversed C/R rating and 750µe FS for unidirectional U/D rating at ±2-mV/V and 3-mV/V output signal levels respectively. Linearity and symmetry of output signal in tension and compression are obtained by equal straining of all shear gages in the bridge circuit of the Flat Load Cell. Barometric or hydrostatic pressures, or vacuum environment do not produce erroneous output signals in Flat Load Cells. Allowable loads that Fatigue Rated Universal Flat Load Cells will withstand for One Billion (10 9 ) cycles without failure are tabulated under Uni-Directional (U/D) and Completely Reversed (C/R) load headings. In Specifications the relation is stated as (U/D) = 150% (C/R). Allowable Intermediate Loads between Uni-Directional (U/D) and Completely Reversed (C/R) Loads can be read off the Limit Chart, where Completely Reversed (C/R) FS Fatigue Load Rating is defined as ±100% at One Billion Cycles. Peak Tension and Peak Compression, as well as Mean Tension and Mean Compression, loads are also given in % (C/R) FS. Low Profile Load Cell Overload allowance in Fatigue Rated Flat Load Cells can only be made at the expense of fatigue life. However, when the required service life of a load cell is less than one billion cycles, advantage may be taken of the reduced fatigue life and the cell may be rated at higher peak loads, per Overload Factors given in Specifications. Once this overload is applied, however, even for a few cycles, fatigue life of the cell must remain at the reduced value. Thus peak load ratings corresponding to one billion cycles should not be exceeded if long fatigue life is an important consideration for the load cell. The load capacity and corresponding life of a Fatigue Rated Load Cell is stated as follows: In the following example consider the case of FFL(180/± 120) U(C)-(3/±2) SPKT Where Uni-Directional (U/D) Rating is 180,000-lbs., and Completely Reversed (C/R) Rating is ±120,000-lbs. From Limit Chart intermediate ratings are available. Say at +50% (+60,000-lb) Mean Tension Load Allowable Peak Tension Load is +133% of 120,000-lbs. = +159,600-lbs. Allowable Peak Compression Load is -33% of 120,000-lbs. = -39,600-lbs. All at One Billion (10 9 ) Load Cycle Fatigue Life. If, on the other hand, required service life of the load is only One Million (10 6 ) Load Cycles, then, from Overload Allowance Chart, all load ratings can be increased by Overload Factor of 1.10, thus: (U/D) = 1.10 X 180,000 = 198,000-lbs. (C/R) = 1.10 X (±120,000) = ±132,000-lbs. At +50% (+60,000-lb) Mean Tension Load Allowable Peak Tension = 1.10 X 159,600 = +175,560-lbs. Allowable Peak Compression = 1.10 X (-39,600) = -43,560-lbs. All at One Million (10 6 ) Load Cycle Fatigue Life
