A neural network is proposed to solve the second-order cone constrained variational inequality (SOCCVI) problems. In this method, a smoothed Fischer-Burmeister (FB) function is used  to deal with the KKT conditions corresponding to the problem, and then the KKT conditions are further transformed to an unconstrained optimization problem. The Lyapunov method is applied to show the Lyapunov stability, asymptotic stability and exponential stability of the neural network under given conditions. The effectiveness of the neural network is verified by numerical experiment.
