Abstract: A testing platform of hydraulic system was built, and the experiments about fine adjusting the pressure of wheel cylinder was performed based on PWM technology. Controlling carrier wave frequency of PWM was confirmed, and the oil-entered valve of ABS was tested with PWM. The duty ratio scope of oil-entered valve of ABS in PWM controlling was asserted. The experienced model of pressure increasing speed of wheel cylinder in PWM controlling was established. At last, the experienced model was validated with the tests.

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.
