Abstract

Valve springs play an important role in the breathing of I. C. Engine. Inaccurate stiffness of valve spring in an I.C. Engine adversely affects the combustion process and hampers the Dynamic characteristics of engine. Therefore, it is very essential to measure the stiffness of spring before replacement. Hence, there is a need of a machine that could easily measure the stiffness and stresses induced in those springs failing which may lead to failure of those springs. This spring testing machine mainly comprises of lead screw mechanism with hand wheel to apply the load, frame and measuring units to measure the applied load and resulting deflection of spring. S-beam load cell is used to measure the load and ultrasonic transducer or sensor to measure the deflection. Interfacing of these sensors with LabVIEW software is done to get the value of spring stiffness directly. Coil springs having diameter up to 50mm and length up to 100 mm can be easily tested on the machine. The second part of the project involves comparison of experimental results with the analytical & simulation results.
