Study on Application of New Kinetic Energy Theorem of Rigid Body Fixed-Axis Rotation

摘要

The classical kinetic energy theorem of rigid body fixed-axis rotation cartnot correctly reflect non-conservative force doing dissipative work, non-conservative reacting force doing equivalent dissipative work at the same time, instead convert the system's mechanical energy into the non-mechanical energy of the bearer. Now these defects are overcome by the new kinetic energy theorem of rigid body fixed-axis rotation.The meaning of new kinetic energy theorem of rigid body fixed-axis rotation is interpreted, the procedures to solve practical problems on new kinetic energy theorem of rigid body fixed-axis rotation and computing methods of the terms in the new kinetic energy theorem of rigid body fixed-axis rotation are studied, as well as the physical significance of the results is described.
