Parabolic flat springs

This type of spring is among flat springs with this difference that for optimization of the weight of consuming materials and homogenization of the tension to spring, the thickness varies in layers' length and usually the length of layers is considered the same. Since the thickness variation is based on parabolic formula, it is called parabolic flat spring.
 The application of these springs is in freight vehicles and wagons and most commercial vehicles use this type of spring.
