Evaluation of Velocity and Acceleration Fields of Quasi-elliptic Drawing Theory

An evaluation is made of quasi-elliptic drawing theory, and acceleration equations are given for the first time. According to the experimental investigations, the authors have developed a series of equations, such as discharging shape, moving trace and moving transition.On this basis, according to the practical observations and theoretical study, the authors have developed the equations of real bulk body's velocity and density, and established the real equation of quasi-elliptic drawing theory. This drawing theory's velocity and acceleration field must meet the contents of evaluation of the velocity and acceleration field about the continuous medium drawing theory. The results show that the velocity and acceleration field of the quasi-elliptic drawing theory can meet the above reqccirements, thus providing the theoretical basis for establishing the systematical and perfect drawing theory.
