It is important to minimize the dissipated energy even in a mechatronic system that repeats start and stop motions frequently. A forklift and an injection molder are a typical mechatronic system that repeat reciprocating motions. The reciprocal motions are realized by a ball screw-nut, which converts rotation into translation motion. The present paper proposes a simple method for determining an optimal...
In order to help reduce global warming, it is important to minimize the dissipated energy even in a mechanical servo system. The present paper proposes a simple method for determining an optimal lead of a ball screw-nut used in the servo system. The rolling friction is represented by the efficiency of the ball screw-nut system. Even if the system is nonlinear due to rolling friction, an optimal velocity...
In order to prevent global warming, it is important to minimize the dissipated energy of machines. This present paper discusses a method for a reduction ratio of gear trains in a mechanical servo system with friction of all types to minimize the dissipated energy. The Coulomb friction of a gear in the servo system is represented by an efficiency of the gear. Even if the system is nonlinear due to...
