Abstract:To develop the passing ability and the ride comfort of crawler power chassis, a set of new suspension system was designed. Each suspension system has 5 separate damping units, and each one includes a hydraulic cylinder and a coil spring. The mathematic model was built according to the structure and mechanical properties of damping units. It was revealed fromKeq-H curve drawn from the mathematic model that the suspension system had nonlinear stiffness characteristic. 1∶4 crawler power chassis prototype and the performance tests were made. The chassis could achieve all terrain profiling and its maximum grade ability was about 60%, its maximum speed was about 3km/h. From the vibration acceleration curve, the absolute value of vibration acceleration was lower than 2.0m/s2. The crawler power chassis with new suspension system is good in its passing ability and ride comfort.

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.
