Fabrication of Spring Stiffness Measuring Apparatus Using Pneumatic System

摘要

Spring is one of the most utilized components in machines, equipment’s in industries.The stiffness of the spring is the characteristic property of the spring which determine both the spring and its application. This paper shows the fabrication and designing of a spring stiffness measuring device based on pneumatic system, which measures the stiffnessof 8 springs(4 compression and 4 tension , wire dia 2 mm and coil dia 3 cm) in terms load and deflection, thereby establishing linearity and making calculations easy.
