This paper mainly aimed to study buffer structure design on the traction transport system when the traction transport boundary conditions were given.With such conditions as the maximum impact force,traction speed,maximum speed of alluvium,the elasticity coefficient and the mass of buffer structure,a mathematical model was established and the solution of differential equations was solved.At last,a program was compiled with MATLAB language.With this program the elasticity coefficient and the maximum impact force which meet the requirements in impact process could be solved as long as the boundary conditions were input.This provided a quick design basis of buffer structure for most mechanical engineers.%主要研究牵引运输中的缓冲结构设计；通过对给定的牵引运输的边界条件：最大冲击作用力、牵引速度、冲击物最大速度、缓冲结构弹性系数及质量，建立数学模型，求解微分方程，得到问题的解；最后通过MATLAB语言对问题的求解过程进行了程序设计，只要将边界条件输入，就可以解出满足要求的缓冲结构的弹性系数及冲击过程的最大冲击力。给广大机械设计人员提供了快速的缓冲结构设计依据。
