“…Many examples can be found on axial force test benches based on the load cell, such as the syringe test stand, catheter track force test, wire bond testing, spring testing systems, medical valve sensors (TAVR fatigue testing), and prosthetic hip fatigue testing. In addition, thrust (axial) force measurements can be found in rocket propellant systems and underwater vehicles [ 29 , 30 ]. For example, the work in [ 29 ] suggests new tension and compression test tools that prevent fluctuation of the measured force of specimen deformation during hardening behaviors for sheet metal forming and spring-back in the automotive industry.…”

The load cell is an indispensable component of many engineering machinery and industrial automation for measuring and sensing force and torque. 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 µV/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.

“…The realization is multidisciplinary because it requires skills in electrical and mechanical engineering. Several laboratories have been interested in the realization of test benches in order to identify their thrusters and a bibliographical analysis made in [15] shows this. The objective of this research is to obtain an accurate dynamic model of marine thruster using a low-cost test bench and a hybrid identification approach, this approach reduce effort in developing complex analytical solution by combining between the simulation parts and the experimental part.…”

In recent years, underwater vehicles play a very important role in the marine field, and tasks cannot be accomplished quickly and accurately without the use of such devices. Despite the progress achieved, these vehicles still have prob- lems with their controls in order to have a very good dynamic positioning or a path tracking accurately, and these problems have a direct link to their thrusters, either by negligence or by ignorance of its mathematical model. Several works were carried out to have an accurate model of them, but its behavior is still diffi- cult to be described and it strongly influences the behavior of a vehicle in which it is integrated. In this work we try to deal this problem in the aim to iden- tify a marine thruster designed by us using a low-cost test bench and a hybrid identification approach, which combines the both experimental and simulation parts. The thruster will be integrated on a remotely operated vehicle under devel- opment by AVCIS-Lab to make simulation using UUV (unmanned underwater vehicle) Simulator and ROS (Robot Operating System) toolbox under Matlab. The outcomes will be presented at the end of this paper.
