Position control system of profile modeling spray for fruit trees;

A sugarcane leaf shattering and returning machine which adopted profiling pick-up device was designed to make it possible that the gap between flail knife and furrow is larger than the ridge height.

Electro-hydraulic profiling system can provide a higher accuracy of profiling in the copying motion, make power machine maintain the steady load at the same time, and overcome the copying distortion on account of moving ahead or lag of time in the overall profiling or combination profiling of before and after components.

The principle and mechanical structure of a new profiling engraving machine was introduced.

Reseach on Parameter Optimization in Blade Copying process and its simulation;

Research on Dynamics of Copying Post of Piston Turning Machine;

A new NC copying machining technique for non-circular piston ring is introduced,which makes it possible to work piston rings with different pressure distribution curve using a kind of cam,and realize error compensation while cam or cutting tool wears away.

This thesis inquires into and puts forward the calculating method of the Cam equation of the profiling structure in translational cam in the process that the inner curve is made by the outer cam profile.
