Keynote address:Research progress of hydraulic active suspension technology
Active suspension technology has been a hot topic in vehicle research in recent years. According to the driving method active suspension can be divided into hydraulic drive, pneumatic drive and electric drive. Among them, hydraulic drive, with its incomparable advantages, leads the development of active suspension technology. This report consists of three main parts. Firstly, introduction of the current research status and existing problems of active suspension technology. Next, introduction of the inertia control principle and basic control method of suspension proposed by the project team of the reporter. Additionally, it discusses the improvement in ride smoothness, handling stability, obstacle crossing ability, and wheel load fluctuation performance indicators after applying this method to all-terrain wheeled cranes and aerial ladder fire trucks. Finally, according to the development trend of suspension digitalization, the transformative impact of new suspension control technology on future vehicle development is prospected.
