The invention relates to a method for carrying out check calculation on secondary spring acting load of end contact type less-taper leaf primary/secondary springs, and belongs to the technical field of suspension plate springs. The method comprises the following steps: firstly calculating an endpoint deformation coefficient and half rigidity of each primary spring as well as a deformation coefficient GxCD, at a contact point of an end straight section and a secondary spring, of the Nth primary spring according to the structure size and elasticity modulus of each parabola type taper leaf primary spring, the end straight section of which is isotactic; carrying out check calculation on the secondary pring acting load according to the thickness of a root straight section of each primary spring, the helf rigidity of each primary spring, a primary/secondary gap design value and the GxCD of the Nth primary spring. Simulation verification proves that the method can be used for carrying out correct and reliable check calculation on the secondary spring acting load of the end contact type less-taper leaf primary/secondary springs, so that the product design level and performance as well as the vehicle smoothness are improved, the design and test expenses are reduced and the product development speed is improved.
