Abstract:The process of heat transfer in tracked vehicle transmission was investigated. A heat transfer model based on lumped parameter method has been developed in order to study heat transfer within the tracked vehicle transmission. And a flow model was established to predict oil flow in transmission fluid system by using 1-D incompressible flow theory. The whole heat transfer simulation model was completed based on the coupling of 1-D flow model to lumped thermal method. The program was carried out, which was used to calculate the heat transfer process under different operating conditions, and simulation results were compared to the test data with good agreement. The solutions are of great value in analyzing the heat transfer for tracked vehicle transmission.

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.
