Influence of complex environment on forging stability of Marine rudder system
Marine corrosion: salt and microorganisms in seawater cause corrosion to rudder forgings, leading to degradation of material properties and affecting its stability.
Temperature change: The temperature change in the Marine environment will cause the temperature difference stress of the rudder forging, resulting in material deformation and affecting its normal operation.
Wave impact: The impact of waves on the forgings of the rudder system may cause structural fatigue, damage accumulation, and reduce its service life.
Ship vibration: The vibration generated by the ship during the voyage may cause resonance of the forgings of the rudder system, posing a threat to its stability.
Research method for forging stability of Marine rudder system
Material performance test: Through tensile, compression, bending and other tests, to understand the mechanical properties of Marine rudder forging under different environmental conditions, to provide a basis for stability assessment.
Finite element analysis (FEA) : The finite element analysis method is used to model the rudder forging, simulate its stress distribution and deformation in a complex environment, and predict its stability.
Environmental adaptability design: According to the influence of complex environment on the rudder forging, its structure is optimized to improve its environmental adaptability. For example, the use of corrosion-resistant materials, reasonable layout to reduce the impact of vibration.
Life evaluation and prediction: Fatigue test and simulation analysis are used to evaluate the life and reliability of rudder forgings in complex environments. The degradation trend of its performance under different working conditions is predicted, and the basis for maintenance and replacement is provided.
On-line monitoring and early warning system: The sensor technology is used to monitor the working status of Marine rudder system forgings in complex environment. When the monitoring data shows that the stability of forging is threatened, timely warning is issued and corresponding measures are taken.
The stability of Marine rudder forgings in complex environment is one of the key factors affecting the safe operation of ships. In order to ensure the stable operation of rudder forgings under various complex environmental conditions, it is necessary to deeply study and evaluate its performance under complex factors such as ocean corrosion, temperature change, wave shock and ship vibration.
