A Review on Materials and Experimental Process used in Air-sprig

Abstract

: The present paper reviews an air spring, its types and construction, manufacturing process, testing and process of FEA analysis. Air spring is of three types - Sleeve-type air spring (SAS), Rolling-Lobe Air-Spring (RLAS), and Convoluted Air Spring (CAS). Spring stiffness is the main factor during manufacturing; to obtain it by FEA analysis and experimentation process is shown. The essential component is either Natural Rubber or Neoprene Rubber. To provide strength and reduce the chances of puncture, fabrics like Nylon and Polyester are reinforced with the rubber and vulcanised. This paper shows the process for obtaining and manufacturing these materials. Metals like Steel, Aluminium, and zinc alloy are also used in Air spring assembly.
