The starting rod is a key component often used in engines, hydraulics and mechanical transmission systems. The study of structure optimization design method aims to improve the performance and reliability of starting rod forgings by changing the geometry, material and process parameters.
In the structural optimization design of starting rod forgings, the following methods can be used for research:
- Design requirements analysis: First of all, it is necessary to clarify the conditions and requirements of the use of the starting rod forging, including load, working environment, service life, etc. According to these requirements, the objective of structural optimization design is determined.
- Material selection: Select the material suitable for the working conditions of the starting rod forging, and consider the strength, toughness, fatigue resistance and other performance indicators of the material. The properties of candidate materials can be evaluated by means of material tests and simulation calculations.
- Geometric shape design: According to the design requirements and material properties, determine the geometric shape of the starting rod forging. CAD software can be used for geometric modeling, and finite element analysis, fatigue life prediction and other calculations to evaluate the performance differences of different geometric shapes.
- Optimization of process parameters: Considering the influence of material processing and heat treatment on the performance of starter rod forgings. Through orthogonal test and other methods, the best combination of process parameters is determined to improve the strength and durability of the forging.
- Structure optimization: Comprehensive consideration of geometric shape design and process parameter optimization results, the use of structure optimization algorithm for global optimization. The commonly used optimization algorithms include genetic algorithm, particle swarm optimization, etc., which can optimize multiple design indexes simultaneously through multi-objective optimization method.
- Verification and verification: Physical manufacturing and testing of the optimized starting rod forgings. By means of fatigue test and strength test, the performance of the optimized design is evaluated to meet the design requirements. If necessary, the design can be adjusted and improved based on the test results.
The above is the general steps and flow of the structural optimization design method based on the starting bar forging. In specific research, it can also be adjusted and supplemented according to specific problems and goals.
