The structural topology optimization and lightweight design of copper forgings of construction machinery is to reduce weight, improve strength and stiffness, and meet the design requirements by optimizing and designing the structure of the forgings.
For topology optimization and lightweight design, the following steps can be taken:
- Set design requirements: Determine the design requirements, including mechanical properties, working environment and quality requirements. According to the specific use conditions and functional requirements, clear the use scenario and stress of copper forgings.
- Establish initial model: Use computer aided design and analysis software to establish initial model of copper forging. Models can be based on the geometry of actual parts or parametric models, taking into account relevant assembly and connection constraints.
- Topology optimization: The topology optimization algorithm is adopted to optimize the initial model according to the given design requirements and constraints, eliminate unnecessary materials and structures, and minimize weight. Common topology optimization methods include finite element method and topology optimization software.
- Optimization result verification: Verify and evaluate the results of topology optimization. Using finite element analysis and other tools, the mechanical properties of the optimized structure are analyzed, such as strength, stiffness and mode. Verify whether the results meet the design requirements and use conditions, and further adjustments and improvements are needed.
- Structure refinement and optimization: Refine and optimize the optimized structure. Including the determination of appropriate materials, processing and manufacturing processes, and local structural adjustment and reinforcement. At the same time, the manufacturability and assembly of the structure are considered to ensure the implementability of the design.
- Evaluation of optimization results: Based on the refined structure, the mechanical properties were evaluated and verified again. The process of optimization and evaluation is repeated until design requirements and conditions of use are met.
Through the above steps, in the design process of copper forgings of construction machinery, the topology optimization and lightweight design of the structure can be realized, the material consumption can be reduced, the performance of the parts can be improved, and the use requirements can be met. At the same time, it can also increase the manufacturing efficiency of copper forgings and reduce costs, and promote the technological innovation and development of construction machinery.
