Spring Stiffness Testing Machine “Spring testing machine are used for different purposes, this include SF1240 series spring testers which are commonly used to test stiffness of disc springs, ware springs, coil springs, and spring type components [1].” The Reference [4] shows the Nagre et al. developed a hydraulic spring stiffness testing machine. In this machine, a hand-operated hydraulic jack is used to cause movement to hydraulic piston rod that compresses the spring to be tested. This force applied for compression is measured through a pressure gauge and deflection of spring is read in units of length.
the stiffness or force of the spring. There are two options for this. One is a load cell and the other is a pressure gauge. Formula for calculating spring stiffness k = force / deflection N/mm. Results: Procedure For Calculation of Stiffness By Using Hydraulic Spring Stiffness Testing Machine. For spring length = 227 mm wire dia. 7 mm.In our project Helical spring load testing machine is used to find out the stiffness, modulus of rigidity, bulk modules for the given coiled spring; it is very much useful for design and inspection of the helical spring.
