电动静液压式互联馈能悬架参数优化与特性分析OA

To enhance vibration damping performance of vehicles under various operating conditions and recover the en-ergy from road-induced vibrations,a novel electro-hydraulic interconnected energy-regeneration suspension system was pro-posed.A mathematical model of the interconnected suspension was developed and used to simulate and analyze the damping force and energy recovery under four conditions by changing the suspension input parameters.The effects of internal hydrau-lic parameters on the suspension's characteristics were compared,and key parameters were optimized to maximize energy re-generation while maintaining the suspension's damping performance.Further validation is conducted under serpentine and bump road conditions to assess the system's anti-roll and anti-pitch capabilities.The results indicate that the suspension's damping characteristics remain consistent,and its energy-regenerative properties are similar under different conditions.Both damping force and average energy regeneration power increase with the increase of frequency and amplitude of road inputs.After optimizing the key parameters,energy regeneration performance is significantly improved.Compared to traditional sus-pensions,vehicles equipped with this system demonstrate superior ride comfort and handling stability.
