The vibration characteristics and durability evaluation of agricultural machinery aluminum forgings is to determine whether there will be fatigue, fracture and other problems during use. The following are the general steps to evaluate vibration characteristics and durability:
- Determine the evaluation methods of vibration characteristics: commonly used methods include modal analysis, frequency response analysis and finite element analysis. Select a suitable method to evaluate the vibration characteristics of aluminum forgings.
- Vibration test: Through the experimental test, obtain the vibration information of aluminum forgings under different working conditions. Sensors such as accelerometers can be used for vibration measurement, and vibration frequency, amplitude, phase and other parameters can be recorded.
- Modal analysis: finite element analysis software is used for modal analysis to obtain the natural frequency and vibration mode of aluminum forgings. For agricultural machinery aluminum forgings, it is necessary to consider its excitation frequency under different working conditions, as well as its interaction with the surrounding structure.
- Frequency response analysis: frequency response analysis is performed according to vibration test data to obtain the frequency response function of the system. By analyzing the frequency response function, the vibration characteristics of aluminum forgings under different working conditions can be evaluated.
- Durability evaluation: Based on vibration characteristics and actual working conditions, fatigue analysis method is used to evaluate the durability of aluminum forgings. According to the fatigue performance curve and stress history of the material, the life and safety factor of aluminum forgings are calculated.
- Optimization design: If the evaluation results show that there are problems with vibration characteristics or durability of aluminum forgings, it is necessary to optimize the design for the problem. The vibration characteristics and durability of aluminum forgings can be improved by changing the material, structural form or increasing the support.
The above are general vibration characteristics and durability evaluation steps, the specific evaluation methods and steps may vary from case to case. In practical applications, it is recommended to seek the help of professional engineers to evaluate and optimize the design.
