Faced with fierce competition at home and abroad, the tower crane design needs to improve design efficiency and reduce manufacturing costs. Introduces the parametric design technology of tower crane based on the secondary development of Pro / E; introduces the principle of solid modeling of tower crane in detail and the parametrization of dimensions through the secondary development of Pro / E based on Automation Gateway Establish the method of relational restraint, and discuss the process of parametric design of tower crane through introduction of parameterized design, assembly and analysis verification; take parametric design and assembly process of standard section as an example, Interface and various parts of the parametric interface design methods and assembly design methods; proposed parametric model, the use of finite element analysis software Ansys static and dynamic analysis to further optimize the design results. The parametric design of tower cranes has accelerated the pace of design and shortened the development cycle.
