This paper describes the design and analysis of the strain gauge load cell, from the conceptional design stage to shape optimization (based on the finite element method (FEM) technique) and calibration, providing ample load capacity with low-cost material (aluminum 6061) and highly accurate force measurement. The amplifier circuit of the half Wheatstone bridge configuration with two strain gauges was implemented experimentally with an actual load cell prototype. The calibration test was conducted to evaluate the load cell characteristics and derive the governing equation for sensing the unknown load depending on the measured output voltage. The measured sensitivity of the load cell is approximately 15 mV\/N and 446.8 \u00b5V\/V at a maximum applied load of 30 kg. The findings are supported by FEM results and experiments with an acceptable percentage of errors, which revealed an overall error of 6% in the worst situation. Therefore, the proposed load cell meets the design considerations for axial force measurement for the laboratory test bench, which has a light weight of 20 g and a maximum axial force capacity of 300 N with good sensor characteristics.<\/jats:p>","DOI":"10.3390\/s22197508","type":"journal-article","created":{"date-parts":[[2022,10,10]],"date-time":"2022-10-10T05:12:21Z","timestamp":1665378741000},"page":"7508","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Design and Shape Optimization of Strain Gauge Load Cell for Axial Force Measurement for Test Benches"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5757-6276","authenticated-orcid":false,"given":"Omar Sabah","family":"Al-Dahiree","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, College of Engineering, University of Baghdad, Baghdad 10071, Iraq"},{"name":"Department of Mechanical Engineering, Faculty of Engineering, University of Malaya, Kuala Lumpur 50603, Malaysia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1662-6334","authenticated-orcid":false,"given":"Mohammad Osman","family":"Tokhi","sequence":"additional","affiliation":[{"name":"School of Engineering, London South Bank University, London SE1 0AA, UK"}]},{"given":"Nabil Hassan","family":"Hadi","sequence":"additional","affiliation":[{"name":"Department of Aeronautical Engineering, College of Engineering, University of Baghdad, Baghdad 10071, Iraq"}]},{"given":"Nassar Rasheid","family":"Hmoad","sequence":"additional","affiliation":[{"name":"Department of Aeronautical Engineering, College of Engineering, University of Baghdad, Baghdad 10071, Iraq"}]},{"given":"Raja Ariffin Raja","family":"Ghazilla","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, University of Malaya, Kuala Lumpur 50603, Malaysia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7637-9297","authenticated-orcid":false,"given":"Hwa Jen","family":"Yap","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, University of Malaya, Kuala Lumpur 50603, Malaysia"}]},{"given":"Emad Abdullah","family":"Albaadani","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Faculty of Engineering, University of Malaya, Kuala Lumpur 50603, Malaysia"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1147","DOI":"10.1007\/s40799-016-0115-8","article-title":"Load Cell Training for the Students of Experimental Stress Analysis","volume":"40","author":"Olmi","year":"2016","journal-title":"Exp.
