Abstract:The active steering system can provide steering intervention to improve the vehicle handling stability. In order to improve the vehicle stability, a rear wheel active pulsed steering system was proposed and its performance was analyzed and verified by simulation and vehicle test. Firstly, a hydraulic pulsed steering system was designed and modeled. A simplified 2 DOF vehicle model was considered as the analytical model, and a rear suspension ADAMS model with the hydraulic pulse actuator was developed. Secondly, the effect of the steering system on vehicle stability was studied and the pulse signal parameters (frequency and amplitude) were evaluated to determine their optimum values. And then, a control structure and algorithm were designed, and the simulations were addressed based on CarSim and Simulink to verify the performance of the proposed system. Finally, a set of hydraulic pulse steering device was designed and assembled to carry out road experiments to assess the applicability of the proposed system. Results from simulation and test indicated considerable improvements in vehicle yaw stability can be achieved and also the roll angle was reduced for improving the vehicle rollover ability. Sideslip angle and lateral acceleration in the peak were reduced by 46.8% and 23.5%, which improved the vehicle lateral stability. Roll factor can be controlled in the set threshold limits \[-08,08\] and vehicle roll angle was decreased by 25.4%, the vehicle anti rollover ability was improved and showed a better control effect than the active steering system. The considerable improvements in vehicle stability can be achieved.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
