In this article we seek to model a base valve of a twin tube shock absorber and study the behaviour of the valve under loaded conditions replacing a mono tube shock absorber. A top down approach was adopted for this work wherein a commercially available shock absorber was stripped down to obtain the individual valves inside. Product teardown was done for the various subassemblies and the base valve was isolated. Modelling was done in PTC Creo 2.0 and the FEA study for the stress and flow analysis was done using ANSYS 15.0. The materials as well as the hydraulic fluid selected for the design were validated and proved to give a better performance than a mono tube shock absorber currently being used in automobiles.

Vibrations are unwanted mechanical phenomena which cause performance deterioration of dedicated equipment and critical electronic hardware. In order to reduce this vibration during the transportation of the dedicated payloads, that is, optical payload or microwave payload and critical electronic hardware such as atomic clocks, detectors and containers with vibration isolation devices are used. Traditional vibration or shock absorbing systems are big in size which makes the whole container huge and bulky. In our present paper, we try to characterise different types of springs (helical and wave) and develop a FEM methodology to calculate the stress and displacement of the springs under load. Generally, helical springs are used with shock absorber systems having large displacement area. Instead of helical springs, we have proposed wave springs. In this study we have selected helical and wave springs for our experiments and compared them for the fulfilment of our objective. The future aim of this study is to select a suitable spring which can be used with a small size damper in order to make a compact vibration isolation system which will provide the same load carrying capacity in a constrained space as that of a traditional system. The CAD files of both the springs are modelled using Autodesk Inventor Professional 2019 and Creo Parametric 5.0, while FEM methodology is performed using HyperWorks 2019 for both the springs. The theoretical calculations of the models are compared with the FEA results and then validated experimentally.

“…Many authors have developed different type of isolators with different elastomeric elements and investigated their behaviours [16]. A survey regarding the recent developments in the isolators is conducted by Ibrahim [15] which reveals that the introduction of nonlinear damping and stiffness in the isolator would yield better results. Such nonlinear damping and stiffness would be possible if we use metallic elastomeric elements instead of rubber.…”

An ideal vibration isolation system should have low transmissibility, extensive isolation range, and stiffness to support any static load. Isolators are designed and developed for various applications where vibrations in the system become a bane to it, we find that most of the isolators use rubber as an electrostatic element while other designs also adopt wire rope and springs. The spring-type isolators are metallic and offer better flexibility in addition to the longevity of their performance as rubber loses its elasticity over the period. Helical springs are extensively used in many applications where the isolator is intended to perform for longer periods. In this paper, we present a detailed design and analysis of the metallic spring conical isolator that finds its application in airborne systems.
