Control on electron beam scanning track in brazing;

In order to use electron beam in brazing of precise structures and thermo-sensitive materials,accommodating every kinds of curve brazing seams,a vacuum electron beam brazing temperature closed loop control system was developed using PID controller,electron beam scanning track editing and on-line adjusting technologies,real-time acquisition and handling of brazing temperature.

By means of the SEBB system,experiments of the structure of four capillary tubes to a plate were carried out with a four-leaf scanning track and PID control method of heating-up velocity.

Analysis of the imaging characteristics and scanning traces of the 45° rotating scanning mirror;

Analysis for refractive property of rotary dual-wedge prism system and 2-D scanning trace

Based on the vector theory of optical reflection,the imaging characteristics and scanning traces of the two-axis pointing mirror are studied.

Study and application of an arc track adjustment device;

Obstacle avoidance for nonholonomic autonomous land vehicle (ALV) is discussed and an obstacle avoidance method based on circle locus is put forward.

Obstacles avoidance for four-wheel nonholonomic autonomous land vehicle (ALV) was discussed, and an obstacle avoidance method based on circle locus was put forward.
