Features
• Lightweight:
Magnesium alloy has a density approximately two-thirds that of aluminum and one-quarter that of steel. Under the same rigidity conditions, it can effectively reduce the overall weight of the vibration platform, facilitating installation and movement, while also lowering energy consumption during equipment operation.
• High Specific Strength and Stiffness:
The specific strength of magnesium alloy is significantly higher than that of aluminum alloy and steel, while its specific stiffness is comparable to those of aluminum alloy and steel, and far superior to that of engineering plastics. This enables magnesium alloy vibration table surfaces to maintain good structural stability and resistance to deformation even when subjected to large loads.
• Excellent Vibration Damping Performance:
Its damping capacity is 100 times that of aluminum and 300–500 times that of titanium alloy. It can effectively absorb vibrational energy, reduce vibration transmission and noise generation, thereby improving test accuracy and equipment stability.
• Strong Electromagnetic Interference Resistance:
Magnesium alloy has good electromagnetic shielding properties, which can effectively prevent interference from external strong electromagnetic fields on the vibration table control system, ensuring stable and reliable equipment operation.
• Good Heat Dissipation:
The thermal conductivity of magnesium alloy is slightly lower than that of aluminum alloy and copper alloy, but much higher than that of titanium alloy. It can quickly dissipate heat generated during vibration, preventing performance degradation due to excessive temperatures.
Application Fields
• Aerospace Field:
Used for vibration testing of spacecraft, such as the ultra-large electric vibration table employed in the construction of China's space station. Its platform is made of magnesium alloy, with a diameter of 4.6 meters, a height of 1.2 meters, and a net weight of 11.3 tons. It can simulate the vibration environment experienced by spacecraft during launch and operation, ensuring their reliability.
• Electronics Field:
Commonly used in vibration inspection equipment for industries such as communications and electronics, such as sweep frequency vibration test machines. These can simulate structural strength tests under actual working conditions, evaluating the vibration resistance of electronic products and identifying early-stage faults.
• Automotive Field:
Serves as a vibration testing platform for automotive components, helping to optimize vehicle structure design and improve ride comfort and reliability. Additionally, the lightweight properties of magnesium alloy contribute to reducing vehicle weight, thereby lowering fuel consumption and exhaust emissions.
