CWGD250 Double Rocker BMU Structure Optimization And Analysis

With the rapid development of economy and urbanization construction, high-rise building by leaps and bounds, Building Maintenance Unit has received widespread promotion, Building Maintenance Unit in order to satisfy different structure form adapted to the specific building roof structure, need to constantly improve the Building Maintenance Unit itself structure and reduce its own weight, improve security. However, for the domestic market, due to the development of the Building Maintenance Unit later, design experience is relatively weak, lead to the inherent design method can’t meet the needs of construction to complicated and varied, seriously restricted the healthy development of our country’s Building Maintenance Unit.In this paper, the research and design of new Building Maintenance Unit as the main task, on the basis of the current existing Building Maintenance Unit model, digital prototype design technology as the main means, to design and research the Building Maintenance Unit of CWGD250. First of all, according to the modern design concept of digital design and technical route, to sure this article Building Maintenance Unit digital prototype design process: design the Building Maintenance Unit â†'three-dimensional entity modelâ†'Digital simulation and simulationâ†'Structure optimization design; Secondly, on the basis of wipe a window machine dynamic parameters, through designing the power of the motor drive power, in order to meet the basic rated parameters of Building Maintenance Unit design, at the same time, through to Building Maintenance Unit rigidity calculation, determine the Building Maintenance Unit in the process of working stability and Building Maintenance Unit the rationality of the design of overall structure; ANSYS finite element analysis software to Building Maintenance Unit main working parts of crane jib statics analysis and dynamic analysis, to verify whether the stiffness and strength meet the design requirements, determine the stability in the working status of; In order to further determine the stationarity of Building Maintenance Unit at runtime, using dynamic analysis software ADAMS Building Maintenance Unit of digital virtual prototype is established, and the lifting mechanism of Building Maintenance Unit dynamics simulation, determine the Building Maintenance Unit in the process of lifting boom of parallel lifting, joint ANSYS analysis software, the mechanics analysis of lifting mechanism, verify the strength and stiffness, Dynamic problems can be converted to statics problem to deal with;Finally, In order to check strength of the whole machine, use of finite element analysis software to Building Maintenance Unit has carried on the finite element analysis, verified the strength, stiffness of the Building Maintenance Unit, and at the same time in the section size of the bar and material thickness as the design variables, in order to reduce material consumption as objective function, to Optimization analysis of the most dangerous parts, in the finally,complete digital prototype simulation analysis process.In this paper, the research results will Provide certain scientific basis and theoretical reference for Building Maintenance Unit and promoted the development of the industrialization of Building Maintenance Unit.
