some research on the line data and pretreatment of line data of urban mass traction calculation system is carried on,and the implementation of graphical edition and drawing function of line and motion curve is researched,the result of them can give solid foundation to the application of system.

The 5th order Hermite insertion value curveof the combination of derived vector parameters is used in designing cam motion curve in the case of the second order continuation, whose characteristics is that apart from satisfying the boundary conditions of inner points, there is still rich freedom which can be used to adjust curve configation.

The paper discusses the optimum design method of motion curve.

Microcomputer automatic measuring system of gyroscope is designed which can collect the moving curve of cursor automatically,fit the data points,describe the real-time curve,compute the measuring result,magnify and reduce the curve,and so on.

Making device for demonstrating curvilinear motion

The paper focuses its attention on the turning motion of the bike in perspective of mechanics and kinematics by analyzing the leading factors affecting the curvilinear motion of the.

The simulation results indicate the algorithm has better performance on not only for straightaway tracks but also curve motion.
