Mechanical transmission scheme optimal design based on a new ant algorithm

To solve the problems of transmission scheme optimization for complex mechanical products, a new ant algorithm combined the simulated annealing algorithm was put forward. The initial value setting of pheromone and update pheromone model of ant algorithm were improved. Commingled thoughts and design rules for the new ant algorithm were discussed. Process model of transmission scheme optimization design based on the new ant algorithm was also constructed. By using the method, the ideal searching direction of global optimal solution could be found as soon as possible and the convergence speed of ant algorithm was also improved, while the shortcomings of high initial temperature required and slow convergence speed of simulated annealing algorithm were also overcame. Application revealed the feasibility of this method.
