With the rapid development of rail transit equipment,lightweight and high performance have become important design goals.Thermoplastic resin-based carbon fiber composite materials have become one of the rapidly developing emerging materials in the rail transit field thanks to their high specific strength,high specific stiffness,excellent impact resistance and process performance.By taking advantage of the welding feature of thermoplastic resins,rapid production of components can be achieved and manufacturing costs can be reduced.In order to quickly analyze the structural performance of thermoplastic carbon fiber composite material welding,a parametric modeling method for thermoplastic carbon fiber composite material welding connection is introduced.The theoretical method and specific implementation steps of parametric modeling for welding connection are expounded.A typical parametric modeling plugin for welding structure is developed.Finally,the effectiveness and practicability of the plugin are verified through examples,and its significant advantages in improving calculation efficiency and shortening design cycle are demonstrated.
