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.
