Ball Motion

The intelligent sports analysis of a soccer ball requires accurately simulating its motion and finding the best design parameters (position and orientation) to kick the ball.  An optimization method is proposed to plan, evaluate, and optimize the traveling trajectory of a soccer ball. The theoretical studies go through the multi-body dynamics modeling, dynamic simulation, and optimal objective modeling Based on Newton second law and Hooke’s law, the motion of a soccer ball is established as the time-dependent ordinary differential equations (ODEs). The expected target is expressed as a function of all design parameters. An example is used to simulate a soccer ball shooting a goal. The result of optimization design has given the most optimal combination of the design parameters, which involve theinitial velocity,initial projectile angle, andinitial orientation angle. This research provides a useful method in predicting the trajectory and adjusting the design parameters for the optimization design of a soccer ball motion.

Body Dynamic

A rigid-elastic coupling multi-body dynamic model of a car was established. The controllability and stability including constant cornering, steering returnability and steering effort performances are analyzed. Results show that there is still a feasibility to enhance the understeer. By optimizing the suspension parameters using DOE method, the characteristic of understeer was improved. Simulation analysis indicated that the characteristics of steering effort and steering returnability were not affected due to change of suspension parameters.

Kane Method

This paper presents the multi-body dynamics modeling of a spherical mobile robot based on Kane method. Based on the kinematics model, the Kane method is employed to analyze the motion of three main parts of robot. A two order dynamics model of spherical mobile robot is obtained. To validate such model, some simulations are fulfilled in both Mathematica and RecurDyn environments. Simulation result shows that, the modeling of spherical mobile robot is correct and effective.
