Motorcycle magnesium alloy forgings, as a key component, need to have good reliability during use to ensure safety and performance. This paper will discuss the reliability requirements of motorcycle magnesium alloy forgings and the common verification methods.
First, reliability requirements:
The reliability requirements of motorcycle magnesium alloy forgings mainly include the following aspects:
- Strength and stiffness: Motorcycle magnesium alloy forgings need to have sufficient strength and stiffness to withstand the load from the engine, suspension system and other aspects, and maintain the stability of the shape.
- Anti-fatigue performance: motorcycle magnesium alloy forgings need to have good anti-fatigue performance, which can not occur fatigue fracture or deformation during a long working cycle.
- Corrosion resistance: motorcycles often encounter various environmental conditions in use, such as humid environment, high temperature, corrosive media, etc., so motorcycle magnesium alloy forgings need to have good corrosion resistance.
- Dimensional stability: Motorcycle magnesium alloy forgings need to have good dimensional stability to ensure that no excessive deformation occurs under different temperature and load conditions, and maintain good matching performance.
Ii. Verification method:
- Strength and stiffness verification:
a. Material mechanical properties test: through tensile test, hardness test and other methods to evaluate the strength and stiffness of the material.
b. Simulated loading test: simulated equipment is used to carry out loading tests on motorcycle magnesium alloy forgings under actual load scenarios, observe their deformation and stress conditions, and verify their strength and stiffness.
c. Finite element analysis: The stress analysis of motorcycle magnesium alloy forgings is carried out with the help of finite element simulation software to predict and verify its strength and stiffness. - Anti-fatigue performance verification:
a. Fatigue test: fatigue test is carried out on motorcycle magnesium alloy forgings to simulate the actual working cycle and observe its fatigue life and fracture.
b. Finite element fatigue analysis: The finite element analysis method is used to predict the fatigue life of motorcycle magnesium alloy forgings, and its anti-fatigue performance is verified according to the actual use conditions. - Corrosion resistance verification:
A. Salt spray test: the motorcycle magnesium alloy forgings are placed in a salt spray environment to observe its corrosion and evaluate its corrosion resistance.
b. Chemical corrosion test: motorcycle magnesium alloy forgings are placed in a specific corrosive medium to evaluate their corrosion resistance. - Dimensional stability verification:
a. Heat treatment and thermal expansion coefficient test: Through heat treatment test and thermal expansion coefficient test, evaluate the size change and stability of motorcycle magnesium alloy forgings at different temperatures.
b. Coordinate measurement: Use coordinate measuring instrument for accurate dimensional measurement of motorcycle magnesium alloy forgings to verify their geometry and dimensional stability.
To sum up, reliability verification of motorcycle magnesium alloy forgings is a key step to ensure its normal operation during use. Through strength and stiffness verification, fatigue resistance verification, corrosion resistance verification and dimensional stability verification, the reliability of motorcycle magnesium alloy forgings can be evaluated and confirmed, and its good working performance and service life can be guaranteed.
