Abstract
Double pig tail conical springs are used in automotive applications such as air braking system, suspension system etc. There is no standard design methodology, analysis and manufacturing data available for double pig tail double conical springs. Also it is very difficult to achieve the required spring parameters like load at fitted heights, minimized transverse loads, coil diameter and pitch. These kinds of spring can have variable pitch, variable coil diameter and variable wire diameter to get the optimum performance. The effects of excessive spring transverse load will cause damage to the adjacent parts like diaphragm, seals, bearings and it also leads to leak thereby affecting the performance of the product. To achieve better design with fatigue life, load at fitted heights and minimized transverse loads, more number of samples are to be manufactured and tested. This is a time consuming methodology and it is also expensive. Computer simulation of these spring design can significantly reduce the time and cost required to meet the optimized spring design. In this paper systematic approach has been established for double pig tail double conical spring design and analysis.
