  • Generally, a working excavator has only one directional bucket tilting angle, which is up-forward. However, side direction rotation of the bucket would allow variety of working output. We designed a hydraulic rotary actuator comprising a double rod hydraulic cylinder with a rack-pinion gear set for use in excavator bucket with side tilting mechanism, thus converting the linear to angular motion. The proposed side tilting rotary actuator was designed with parts suitable for medium size of heavy duty excavator. These mechanical parts were inexpensive to purchase and the manufacturing cost was reasonable. The proposed mechanism is potentially useful for excavator with variety of working output.

  • A dynamic analysis of a tilting actuator for projection TV is presented in this study. Generally, an excessive vibration of a tilting actuator is occurred a lowering of video quality of projection TV because of a dynamic unstability of it. Therefore, a dynamic analysis of a tilting actuator system is positively necessary. In this study, a mathematical model about a mirror-reactive type tilting actuator is presented and evidenced by experiment. A FEM model of a lens-transmissive type tilting actuator is presented and we made prototype of it. Then, it is evidenced by experiment. Besides, a design for hinge configuration of it is presented.

  • This paper describes a lens transmissive type tilting actuator for a projection TV. An electromagnetic analysis and a structural analysis of the tilting actuator system is necessary to design a tilting actuator for a projection TV. The tilting actuator is composed a permanent magnet, coil and yoke as the electromagnetic components and it needs a driving hinge part as the mechanical component. The design of the tilting actuator for the projection TV is performed by the following procedure. Firstly, a magnetic flux density of the tilting actuator system is analyzed by a mathematical theory and an electromagnetic FEM. Secondary, a magnetic circuit method is used to determine tilting force. Thirdly, the structural FEM is carried out with an FE model of a lens-transmissive type tilting actuator and then the prototype of the model is manufactured. The characteristic of the prototype is experimentally observed. Finally, a design for a new hinge configuration is suggested for better performance.

  • In this paper, it is proposed to substitute the tilting operation device of hybrid multi-D.O.F system from three phase SPM to single phase torque actuator. When using tilting operation with three phase SPM which is appropriate for continuous rotary operation, there are disadvantages that electricity availability rate is low and controllability is difficult. On the other hand when using a single phase torque actuator instead of SPM, it is appropriate for sequential tilting, electricity availability rate is high, and it is easy to control. Thus this will have a great influence on the development and practical use of the system. This study designed a single phase torque actuator in consideration of the magnetic saturation. Also, this was verified with comparative analysis with SPM through FEM(finite element method) analysis values of the design model and test values of the manufactured model.
