Automation of Axisymmetric Crimping Simulations for Pneumatic Suspension Components using Python in Abaqus/CAE

Abstract The paper presents the development of an axisymmetric numerical model for simulating the crimping process of pneumatic suspension components and the implementation of a Python script integrated into the Abaqus/CAE environment. Automation through the Abaqus Scripting Interface (ASI) significantly reduces preprocessing time and eliminates repetitive manual operations. The axisymmetric model describes the deformable behavior of metallic and elastomeric components, using CAX4R and CAX4H elements to ensure numerical stability and result accuracy. The script automatically generates geometry, material properties, contact definitions, boundary conditions, and analysis steps based on data provided in a parameterized Excel file. The proposed solution ensures consistency between simulations, allows rapid execution of parametric studies, and facilitates integration into industrial design workflows. The results demonstrate the efficiency of Python scripting in automating FEA-based analyses for complex industrial applications.
