2002 Annual Conference of China Mechanical Engineering Society.
Development and design of angle reducer for ladle drive unit Guo Weiqiang Cui Yonghong Characteristics and structural characteristics of Mianyang 629,0 Wang Chunyu, Institute of Engineering Physics, China Institute of Engineering Physics.
14 arc ultrasonics 0 welding technology Zhou Ronglin Guo Delun Li Congqing Gao Yan Zhang Yanjun microscope and 8 observation joint structure and fracture, using universal inspection machine to test joint tensile properties. The results show that the grid is in accordance with the Hangkong standard 14 conventional Ding 10 welding and arc ultrasonic welding, the joints obtained reach the aviation grade; with the increase of the ultrasonic frequency, the excitation voltage increases, the arc ultrasonic 15 welded head width Gradually decrease, the weld structure is refined and equiaxed, the damage of dendritic damage is not obvious, and the tensile strength and elongation of the joint tensile strength are all mentioned.
Microstructure and Mechanical Properties of 212,3 Ceramic Materials Huang Fax, He Jing, He Lin, Liu Youlian, Fang Zou, Zou Bin, School of Mechanical Engineering, Shandong University, Jinan 250061, China. The results show that with the increase of 1203 content, the grain size of the material gradually decreases, and the content of the phase 1 in the material increases, which is beneficial to the improvement of fracture toughness and flexural strength of the material; when the content of magical 2, 3 is 2, B is called 12, and the comprehensive mechanical properties of the composite ceramic materials are the best.
