Abstract

This paper describes design and fatigue analysis of mono leaf spring. Weight reduction is now the main issue in automobile industries. In the present work, the dimensions of an existing mono steel leaf spring of a Maruti 800 passenger vehicle is taken for modelling and analysis of mono leaf spring with two materials namely, steel and Carbon/Epoxy subjected to the same load. The design constraints were stresses, deflections, damage, and life and safety factor. The two different leaf springs have been modelled by considering uniform cross-section, with unidirectional fibre orientation angle for each lamina of a laminate. Fatigue analysis of a 3-D model has been performed using ANSYS workbench. Keywords: Composite leaf spring (CLS), Fatigue analysis, Steel, Carbon/Epoxy. The fatigue analysis is performed under different repetition loads 250 and 397.27 with different time 10, 20, 30 and 40sec respectively.

Abstract

Hydraulic and pneumatic system equipments are the important components of engineering applications. Hydraulic cylinders are one of the most common components of the hydraulic systems used in many engineering applications like; automatic manufacturing and montage lines, heavy construction equipments, control systems, sensitive measurement and test systems. They are used for producing linear motion in the hydraulic systems and they convert hydraulic energy to mechanical energy. Many machines and machine mechanisms run under static and dynamic working conditions. The vibrations produced under static and dynamic conditions affect many important design parameters such as strength, production costs, productivity. In this paper, the dynamic and static analysis of a composite hydraulic cylinder subjected to pressure by varying fibre orientation and different boundary conditions is determined. The finite element methods used in the analysis are applied by using analysis software ANSYS.

Keywords

Static and Modal Analysis, Hydraulic Cylinder, Finite Element Method, ANSYS.
