Effect of Geometrical Parameters on Sensitivity and Volume of Rectangular Beam Force Transducer

Vaibhav Varne, Vasudev Shinde, Vijay Kamble


Load cells are transducers employed to measure force or weight. There is a wide variety of transducers;most of these transducers are based on strain gauges. In current research, optimization of strain gauge basedtransducer is carried out by maximizing sensitivity and minimizing the volume. A simple strain gauge based model of ‘Rectangular Beam Type’ load cell is considered for finite element method and finding an effect of critical dimensional parameters on sensitivity and volume. The experimental plan is constructed based on Response Surface Methodology (RSM). Next, multi-objective optimization is performed. Analysis of variance (ANOVA) is carried out to get contribution of each parameter on the performance characteristic.
