HYDRAULIC SPRING STIFFNESS TESTING MACHINE. INTRODUCTION: A engineer is always focused towards challenges of . The most important properties of the hydraulic drives determining their use in the production machines, manipulators, robots and testing equipment are high power to weight ratio, good controllability of pressure and flow, high dynamics, fast time response, simple transformation of the hydraulic power in the mechanical power of the longitudinal motion.International Journal of Emerging Engineering Research and Technology Volume 2, Issue 7, October 2014, PP 184-190 ISSN 2349-4395 (Print) & ISSN 2349-4409 (Online)In many engineering machines and mechanisms spring is an essential component used for proper functioning of that machine for maximum efficiency, there are many applications of springs in automobile suspension system, IC engine valves , brakes, clutches, measurements of weights, for storing energy such as in spring type accumulator, in shock absorber, in hydraulic .

A digital spring stiffness testing machine comprising hydraulic cylinders of different diameters interconnected by same liquid was designed by Jadhav et al. (2014).Avdhut R. Jadhav [1] has prepared a hydraulic spring stiffness testing machine. It has been made up with two hydraulic cylinders of different diameters. Such hydraulic cylinders are interconnected .The hydraulic spring stiffness testing machine was designed is cheap as compare to digital stiffness testing machine. Hence this machine, it can be used in garages and small industries. It is easily manufacture in workshop. Ashfaq J., Basit Ali, Musawwir F., Huzaifa K. and AafaqG.[4]Inthis paper they have developed a machine that .

Springs are used for a wide range of products in heavy duty industries such as automotive, aerospace, railroad and military as well as in everyday household assemblies such as pens, beds, chairs, watches and staplers.To make sure that the springs live up to the strictest tolerance requirements, springs are tested on dedicated spring testing machines, also known as . In many engineering machines and mechanisms spring is an essential component used for proper functioning of that machine for maximum efficiency, there are many applications of springs in automobile suspension system, IC engine valves , brakes, clutches, measurements of weights, for storing energy such as in spring type accumulator, in shock .This spring testing system is equipped with three test axes to measure the damping characteristics of the hydraulic shock absorbers.The vertical force (wheel load) is applied by the testing machine axis. Horizontal forces and torsional moments that occur when maneuvering curves, when starting or braking, etc., are generated by a horizontally mounted .In many engineering machines and mechanisms spring is an essential component used for proper functioning of that machine for maximum efficiency, there are many applications of springs in automobile suspension system, IC engine valves , brakes, clutches, measurements of weights, for storing energy such as in spring type accumulator, in shock absorber, in hydraulic .

In Industries they purchase the springs for their hydraulic valves but they are facing the problem of checking the spring stiffness. After understanding the Industries problems for spring testing we designed and developed hydraulic spring stiffness testing machine. Only considering the two parameters load and deflection) we can calculate spring stiffness. The machine is .

The working of hydraulic stiffness testing machine is based on Pascal’s law which states that PRESSURE APPLIED AT ANY POINT ON ANY CONFINED LIQUID IS TRANSMITTED EQUALLY TO ALL OTHER POINTS” This principle is same as that used in hydraulic press. After understanding the Industries problems for spring testing we designed and developed hydraulic spring stiffness testing machine. The main objective of this project is to determine the stiffness which is commonly known as spring constant of a compression spring under various load. The kit which has been built into a machine to stretch or . 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.
