INVESTIGATING THE EFFECT OF THE VARIOUS STIFFNESS COEFFICIENT ON THE CONTROLLED DAMPER MASS SPRING SYSTEM BASED ON THE ELECTROMECHANICAL SENSOR

This work is concerned with investigation the effect of the stiffness coefficient for the spring elements in the mechatronics applied system consists of damper mass spring system linked to the electrical position sensor. The suggested approach contains experimental work as well as theoretical analysis to meet the demand of the proposed system. In the application of the system; the practical work requires to set up a test rig involves the apparatus as well as three models of spring which has been selected to achieve the desired performance. It has been treated as un-damped vibrations case to measure the tolerance in the displacement distance with respect to specified reference point due to apply various values of mechanical load. The electrical position sensor has been used to convert the obtained values of the displacement distance to corresponding value of electrical signal which has been sent to electrical control unit. Comparison between practical and theoretical results has been carried out to realize the best results of the employed system. The simulation process results with using Matlab software package showed that there is a much greater similarity between the obtained practical and theoretical results and the proposed model can be applied with high efficiency. The little bit difference between theoretical and practical results may be occurred due to the accuracy of the employed measurement devices.
