Simulation of Residual Stress in Cold Working of Flat Spiral Springs

Abstract:

Spring residual stress is a great influence on the overall performance of springs. In this paper, a flat spiral spring is taken as the research object, based on ABAQUS, the finite element model of residual stress during cold working of flat spiral springs is built. The magnitude and distribution of residual stress in cold working of flat spiral springs are simulated under different parameters. The effect of residual stress on the use performance of flat spiral springs is investigated. Optimization of process parameters is acquired. A reasonable processing technology is formulated, which provides theoretical basis for the cold working process.
