Abstract:In order to effectively realize the damping control and regenerative energy recovery of vehicle suspension, electro hydrostatic actuator (EHA) technology in the aerospace field was introduced into vehicle suspension system and a kind of vehicle semi active suspension with EHA was put forward. For the following simulation analysis of suspension performance, 2 DOF mechanical model of vehicle semi active suspension and EHA mathematical model were established. The EHA prototypes were designed and developed for test parameters identification and regenerative energy recovery. Then, the characteristic tests of the generator and energy regenerative tests of EHA were completed. The optimal control and energy management control strategies of EHA semi active suspension were designed. The dynamic performances and energy regenerative characteristics of semi active suspension with EHA were simulated by AMESim and Matlab/Simulink software. The test bench systems for semi active suspension were developed. Then, the tests of semi active suspension with EHA were done. The simulation results show that for semi active suspension with EHA, sprung mass acceleration drops by 23.97%, suspension dynamic deflection drops by 18.36%, and tire dynamic load drops by 11.50%. And the energy regenerative efficiency is 36.4% under vehicle speed of 30km/h and C level road excitation is 67.4% under amplitude of 0.05m and frequency of 4Hz sinusoidal excitation. The test results show that compared with passive suspension, sprung mass acceleration of semi-active suspension with EHA drops by about 20%. The damping effect of developed semi-active suspension with EHA is obvious.

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.
