The Manufacture and Properties of Automobile Suspension Springs

In this paper is given a description of the manufacture of laminated, coil and torsion bar springs, together with some notes on the various defects which may arise and the precautions taken to prevent them occurring.The mechanical properties of springs are discussed, and tentative design data are presented.Consideration is given to shot peening and scragging, and an analysis is presented of the internal stresses caused by these processes.The MS. of this paper was received at the Institution on 23rd May 1953.
