Simulation of the Critical Velocity Dynamical Characteristics of Spherical Grain of Agricultural Material

Under the integrated environment of SIMULINK, the simulation of the movement process of spherical grain of agricultural material in liquid is operated with the basic principle of critical velocity dynamical characteristics. The simulation model may accomplish three objects including that it may obtain the curves of displacement, velocity and acceleration while material grain is moving in liquid, calculate the value of critical velocity and display the time that it is right to reach that value.
