All along, the Bucket, circular stacker-reclaimer FEM analysis, are used to design the program first, then design the finite element calculation device model based on the program. Equipment as a result of the establishment of a detailed calculation of the finite element model of a large workload, therefore, in the design of the results of the calculation results has been scheduled for this process will generate a lot of time spent, and as a result of the analysis software designers themselves are not necessarily well versed in the analysis of During that time, on the work of designers created a blind spot, reducing the efficiency. Secondly,as many designers and analysts when there is room for differences, as well as modifications in the model, the designers and analysts will spend a lot of exchanges of energy, resulting in waste.Consider the characteristics of designers, they design programs to develop, so the key components for the various parts of equipment size will be very sensitive to and familiar with the results of the analysis for the request, for a typical device, the results of its request that there is great similarity. Take into account the above characteristics, if there is a system of staff in the design of the case of input parameters can be automatically generated finite element models and automatically calculated by the designer to extract the required results, you can greatly improve the computational efficiency and speed up product development speed .Described in this paper YDQ system parameters is developed based on these ideas. Designer import the parameters in user interface (PMS system),after that obtain finite element anlysis result based on the parameter about the equipment,and output the data in the docment.The system uses ALGOR finite element analysis software, with PMSG parametric modeling system. Use DOS language system, ALGOR programming languages Eagle and Scripts to complete assemble and auto-parts analysis.YDQ parameters of the system is Cooperation with the Changchun Co., Ltd. power equipment. Completing the entire system spend nearly a year.The first phase: receiving Changchun Co., Ltd. provided power generation equipment YDQ90 Stacker detailed design drawings, according to the establishment of a detailed model of the drawings, the design has been to conduct a detailed analysis of the results of detailed calculations;The second phase:The Stacker YDQ90 structure-based design, the circular stacker-reclaimer is divided into newel,anticipate arm,turnplate,gantry,upper bracket and Long men six parts, use PMSG parametric modeling process is complete all parts of the parametric modeling;Phase III: the assembly of existing components of the model parameters to handle connections, as well as the constraints imposed load, the realization of the automatic calculation of the model and extract the required results;Phase IV: The results of the extraction of secondary processing, by setting the output format for results;Phase V: The results of detailed calculations of the system and parameters and are coMPared with the parameters of the system to verify the validity of the calculation and improve the system design completed;Phase VI: Business exchanges, and consider the recommendations of coMPanies to carry out further changes to the system, and guide enterprises to use. Now the system has been applied into the users, after a few exchanges to improve, users have mastered the use of the system and applied to the actual design.YDQ system parameters of the system of finite element software is ALGOR, but the framework of this system is very versatile, when the finite element method using ANSYS software, simply to the internal procedures of the modified executable program, programming language ANSYS programming language into the same framework can use this system to achieve the use of ANSYS software system parameters.
