1. Wu, Dong-yu. Effects of Morphological Factors of Hexapod Robots on Locomotion Stability.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2009, NSYSU

This thesis studies the effects of morphological factors of hexapod robots on their locomotion stability. In particular, an offset model for such robots is proposed. The stability margin as well as the error margin are used to indicate the stability of the hexapod robot, as it walks with different gaits in arbitrary directions. Two hexapod gaits are compared, which are the symmetric gait and the metachronal gait. The former is an artificial gait and the latter, on the contrary, is a natural gait which can be observed in many multiped animals. As we investigate advantages and disadvantages of the two gaits, we find that the stability of a hexapod robot can be enhanced by increasing the offset value. This is particularly true for a robot moving in the X and oblique directions with a symmetrical gait. However, altering the offset is less useful for metachronal gaits. In general, a hexapod robot moves most stably in the Y direction with a symmetrical gait, whereas it is most stable in the X direction with a metachronal gait. Advisors/Committee Members: Cheng-Ho Hsu (chair), Kuen-Ming Li (chair), Innchyn Her (committee member).

Subjects/Keywords: Metachronal gait; Symmetric gait; Error margin; Stability margin; Offset model

2. Hu, Yung-ming. Effect of Machining Parameters in Vibration-Assisted Micro Grinding.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2010, NSYSU

Cutting fluids have some drawbacks, like health hazards, extra manufacturing cost and environmental contamination. To decrease the disadvantages of using cutting fluids, conventional cutting is a better choice. However, conventional cutting has no advantages of using cutting fluids, such as lubrication. Therefore, vibration assisted cutting (VAC) is a new technology to achieve both purposes of the above machining techniques. Hence, the goal of this study focuses on the mechanical performance of vibration assisted grinding (VAG) for micro grinding of SKD61 steel based on tool life and surface finish. In this study, it is observed that chatter happens under VAG in the condition of feed 5.76 μm/rev. Surface roughness (Ra) for the condition of feed 1.92 μm/rev is better than that of 5.76 μm/rev. The best surface finish is 0.05 μm in this study when the feed is 1.92 μm/rev. Spindle speed does not have significant effect on surface roughness in this study. However, the tool life is short under high spindle speed (35000rpm). Experimental results show that tool life will be prolonged two-thirds for VAG combined with MQL. As changing the amplitude of vibration (for a fixed frequency of 9 kHz) , the larger the amplitude, the better the surface roughness. Advisors/Committee Members: Inn-chyn Her (committee member), Yuang-cherng Chiou (chair), Kuen-ming Li (committee member).
