ESTABLISHING CORRELATION BETWEEN LEAF SPRING’s SPECIFICATIONS AND CAMBER DROP

Camber drop is the study of the differences between the actual camber and the desired camber (master camber). Camber is one of the importing specifications that need to be followed by manufacturer to avoid rejection of the products by the customers. However, the manufacturer is said to be having difficulty in producing leaf spring with a camber matches the desired specifications in a first attempt, which can cause them to the losses in term of time and money. The importance of this study is to find a correlation between the leaf spring specifications and camber drop, and to establish an equation that can be used to estimate the amount of camber drop. This project is to be conducted by collecting the data required, which are the Quenching Camber, Half-length of the spring, Spring Rate, and End-thickness of the spring. All the data collected then will be converted into a graphical presentation based on each specs to start the finding of the relation and also to govern the equation of estimation of the camber drop. It is expected to obtain the correlation between the leaf spring specifications and the camber drop, and also to be able governing the equation of estimation of the camber drop.
