An Analysis of Structural Optimization Methods and Performance Improvement of Hydraulic Lifts

The reliability and performance of hydraulic lifts directly affect safety and energy efficiency. With increasing automation and heavier load demands, safety and performance criteria have tightened, hence making structural optimization vital for improving reliability and prolonging service life. This paper reviews current structural optimization methods for hydraulic lifts and their performance enhancements, emphasizing the application and impact of topology optimization, geometric reinforcement, and material substitution strategies. By analyzing relevant literature, it highlights the specific influences of different optimization methods on lowering weight, reducing energy use, and extending fatigue life. The results indicate that topology optimization reduces weight by 15% to 30% but increases stress at welds, geometric reinforcement lowers bending moments and energy use, and material substitution like carbon fiber composites cuts weight and boosts durability despite adhesive uniformity challenges. Yet, computational inaccuracies and high material expenses continue to restrict the broad adoption of these optimization techniques. Future work should combine digital twins with physical tests and advance certification frameworks based on artificial intelligence to accelerate industrial adoption of structural optimization.
