AbstractThe spring is an important mechanical part of which widely used in many industrial applications. There is an urgent need to know its stiffness property before use in any application. Since the stiffness varies according to the method of using the spring in this research, it is suggested to calculate the lateral stiffness of spring by the moment effect. the device meter of the lateral stiffness of conical springs has been designed and manufactured working principle applying a torque to the head of the spring and calculating the angle of inclination. This research includes an experimental aspect (tensile test of steel wires, manufacture of the device lateral hardness meter, manufacture of four conical springs from steel wire inspected with diameters of 3.4, 3.8, 4, and 5 mm, and testing the springs with the manufactured device). As for the simulation aspect, it comprises calculating the lateral stiffness by numerical analysis using the solid work program. After extracting the hardness values practically by the device and comparing them with simulation values, the device proved its efficiency for small diameters after the experimental results have been compared with the results of the simulation, as the error rate increased with the increase in the diameter of the spring wire, so the highest acceptable error that could be reached by the device was 5% for the diameter 4.36 mm and zero error at the diameter 1.2 mm.
- The meter able to use on conical and helical springs
- The meter is efficient for conical springs that wire diameter ≥ 4.36 mm.
- The meter read error rate disappears at wire diameter ≥ 1.2 mm.
