Abstract:2.7%。The magnitude of residual stress and the depth of dent are two important factors to assess the effect of laser shocking. They were simulated by numerical analysis software. During the simulation, the key technology was solved and the mathematical model was established. The experiment was also carried out to test the results of simulation. The simulation results were well agreed with the experimental results. The deviation of the depth of dents between calculated results and experimental data is 5.78%, and the magnitude of simulation of residual stresses is 2.7%, which indicated that the numerical simulation could play a directional role in optimizing parameters to improve effect of laser shock processing. 

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.
