This paper briefly touches upon the mechanics of strain gauge load cells and states the
problem of strain gauge load cell design. The mentioned problem is subdivided into two
tasks: picking and choosing the shape and the dimensions of the elastic element, and
finding the right spots for mounting strain gauges on the elastic element. We created
a system for designing strain gauged load cells having axis symmetrical elastic elements.
The system implements the method of parameter space investigation and utilizes capabili-
ties of the CAE system ANSYS. The system’s capabilities are demonstrated by designing
a load cell for Weigh-In-Motion scales. Solution of this design problem comprises defin-
ing the parameter space and setting the values of the criteria constraints. We investigated
the parameter space using the system mentioned above. Finally, we developed a finite-
element model of the load cell being designed. The numerical experiments resulted in
a Pareto-feasible set, which is given to the Decision Maker, so that he could choose the
best option.
Keywords: multicriteria design, finite-element method, elastic element, the parameter
space investigation method, strain gauge
