Discussion on pavement reconstruction using impact compaction technique;

Dynamic stability analysis of gravity retaining walls under impact compaction;

Researches on impact compaction test of rock-soil filled roadbed in high-grade highway;

Microstudy on roadbed loess improvement by impact compaction technology;

Discussion on investigation before application and decision of impacting compaction technique;

The quality of compaction for high-filling areas is studied by use of impacting compaction to improve particle-size distribution of broken stone,the compaction effect,and reduce deformation of high-filling.

Impacting compaction is a new method to strengthen soil mass.

Study on the man machine decision system of the pressing process;

The structure characteristics and pressing process of the connection piece were analyzed, and the layout design of the part, the structure and main characteristics of the die were introduced.

Based on analysis of pressing process noise and its general control approaches,the active control principle on pressing process noise is expounded and some new active control techniques used in pressing process noise are typically introduced and suggested,such as two steps blanking method,reduction of blanking noise.

Analysis of punching process for the enhanced support of CS7

Through analyzing the structure characteristics of the stopper support, determined the punching process, and simply introduced the design method of dies.

Taking the top plate frame as the example, analyzed on the part punching process,the part contour shape was complex, and the forming request was high.
