[Abstract]:Tower crane is widely used in industrial and civil construction, transportation, electric power and water conservancy construction and shipbuilding engineering. The working mechanism of tower crane equipment includes lifting mechanism, amplitude changing mechanism and rotary mechanism. Truck operation mechanism (fixed tower crane is not used) to complete the whole process of lifting work, that is, lifting heavy objects, transporting heavy objects to the designated place and installing the heavy objects in place, and so on. The design process of tower crane and the design process of software are studied, the architecture of tower crane CAD system is analyzed, the user interaction mode and interface structure are determined, and based on the principle of function decomposition, The CAD system of tower crane combines modular design and object-oriented programming organically, and uses Visual C as the main development tool to construct the function module of tower crane according to the modular design, which makes the function module more cohesive and less coupling. The encapsulation, inheritance and polymorphism of object-oriented programming make it easy to reuse and extend code. It is easy for designers to think abstractly and to improve the readability and reusability of code. The function module interface of tower crane is constructed by object-oriented programming. The function module of tower crane represents the attribute and realization behavior by encapsulating data and methods in the object, which makes the design and calculation of tower crane more programmed and standardized. In the process of tower crane design, a large amount of attribute data, performance characteristics need to be optimized, and the parameters of tower crane design and calculation have randomness and uncertainty. The parameter optimization module of tower crane is constructed, and the mixed programming of MATLAB and VisualC is adopted. Using Visual C to create the optimization interface, borrowing the excellent algorithm of MATLAB and calling MATLAB optimization toolbox to solve the problem in the background, a more scientific, reasonable and objective optimization design scheme is obtained. ADO technology is used to establish seamless integration of application program and Access database, to realize reasonable data flow and communication, to use structured query language SQL and message-driven mechanism to realize operation behavior, to realize data reuse, and to reduce redundancy. Accurate and reliable results are obtained.
