Modeling and simulation of system design adjustment is respectable training for design and engineering decisions in real world jobs. In this paper, the exact perseverance connected with the strain of components is very important for structural designs, analyses, and for excellent control. The information linked to this type of test is usually related to the exact dimensions connected with the pressure within a flexible region. This paper proposed the design and simulation of a torque sensor with a piezoresistive V-shaped strain gauge. The piezoresistive measure of a precious metal for a stable base was made according to the results of an ANSYS simulation. A torque sensor with a piezoresistive V-shaped tension measure on a base was made. The result of the particular simulation shifted the fraction of tension on the base to enable the torque on the substrate to be measured. Theoretical studies on the piezoresistive measure of a metal for the stable base as well as the torque sensor were introduced. A maximum of 127.29 με and a maximum resistance change in gauge equal to 0.091Ω were achieved for an applied torque of 22.0725 Nm. Here, computer systems modeling and simulation are going to be used.

Static Torque

Professionals and students alike create high-performance Remotely Operated Vehicles (ROV)s to complete a multitude of tasks underwater. The student ROV competition created by Marine Advanced Technology Education (MATE) simulates the tasks faced by the modern professional underwater robotics industry. Students often design their ROVs with techniques used by the professional underwater robotics industry. Unlike professionals, students do not have many resources comparing manufacturable ROV components that fit within their design restrictions. Without information about components that they choose to use on their ROVs, students might miss an opportunity to implement a better alternative technology. Such is the case with older Shaft Sealed Housings (SSH) and less common Magnetically Coupled Housings (MCH). In this paper, essential aspects of both alternative designs for waterproof motor housings are tested to determine overall performance. The waterproofness of each housing is tested experimentally over long periods of time in an environment simulating the most extreme depths experienced at the MATE ROV Competition. Maximum static torque is measured on a torque sensor. Cost and manufacturability of each housing are recorded in tables. Ultimately, student robotics teams are left to determine which motor housing best fits their design requirements, based on the data discovered and presented in this paper.

This paper deals with the head-type torque sensor, on the basis of magnetoelastic effect, installed on the main shaft of machine tool for sensing cutting torque in order to monitor cutting process. The tests of two types of sensor are carried out under various cutting conditions. In order to confirm the accuracy of these sensors measuring cutting torque, the torque values obtained by two types of magnetic torque sensor are compared between measuring value of strain gauge and calculating value of cutting force experimental formula. The investigation demonstrates that the on-line monitoring of cutting force can be detected through measuring cutting torque by means of magnetoelastic torque sensor, and the cutting state can be shown by cutting parameters.

Reaction Torque

Various high-performance force/torque sensors have been developed for the purpose of advancing automation systems. However, the demand for simple torque measurement of rotating shafts continues to exist, and expensive multi-axis sensors need not be wasted here. In this paper we propose a simple motor-equipped single-axis reaction torque sensor to measure the applied torque continuously using a load cell. The proposed sensor has long lever and base linkages, and the adjustable moment arm consequently enables adjusting measurement range and sensitivity by repositioning the assembled load cell on the two linkages. This paper shows the design of the proposed torque sensor, and it is evaluated by experiments for various applied torque and lever length. Moreover, the sensor is applied to an existing example: a commercial balanced-arm lamp with and without its balancing spring. The proposed torque sensor can continuously and successfully measure the applied torque, and it will be utilized in various industries and laboratories without much money.

Face Mill

Machine tool supervision and control algorithms require reliable and effective sensor signals to operate properly. In effort to satisfy this need, a high stiffness, wide bandwidth torque sensor for use in milling has been developed which directly measures the torque applied to a milling cutter during operation. The sensor is designed to fit between the tool and holder on conventional tooling with very little effect on the cutting process. The sensor is strain gage based and provides a virtually distortionless torque measurement over a bandwidth from DC to 2000 Hz when using a 100 mm diameter face mill on a commercial machining center. High torsional stiffness was achieved to provide a wide measurement bandwidth while allowing enough material strain, in the sensing element, to provide sufficient resolution of the milling torque. The radial stiffness of the sensor was also designed to be large enough not to compromise the stability and accuracy of the machine tool. The sensor is designed to house the critical electronic components which amplify the small voltage strain gage signal and convert the measurement into digital samples. These samples are continuously transmitted from the rotating spindle, in all positions, to a stationary receiver. Because the sensor is part of a structural system which also includes the spindle, tool holder and tool, the frequency response has distortions associated with the vibrational modes of the system. In order to obtain a wide undistorted bandwidth, a compensation filter having the reciprocal response of the sensor has been designed and implemented on a digital signal processor (DSP). The combined system of the sensor cascaded with the DSP provides a flat magnitude and linear phase frequency response.
