It has some advantages and disadvantages compared with other processes (casting, welding, stamping, etc.). For example the advantages of the shot peening process: the process has the simple equipment, low cost of doing, not restricted by the shape and location of the parts, easy operation, etc. And the disadvantage is the poor operation condition ([1], [2], [3]). Index Terms—Shot peening process, Finite element analysis, Python script, Residual stress, Random impact model I. INTRODUCTION The finite element analysis (FEA) is a method which uses the mathematical approximation method to simulate the real physical system (geometry and loading conditions). And based on the simple and interacting elements which are called unit can use a limited number of unknown variables to approach the infinite unknown quantity of the real system. With time, the engineer has developed so many finite element software which can be used at some areas, and we can use the finite element to do simulation which can see the condition after the stress and others boundary conditions. Firstly we use the intrinsic component in ABAQUS to do the simulation and find that the intrinsic component is difficult for the definition of the boundary conditions. Because of the distributed arrangements and sequences are predetermined by an intrinsic component which is far from the random impact model in actual production. I need to get the random impact model we developed a random impact model by python language in ABAQUS, and run
