A Modal Analysis for a Hung Euler-Bernoulli Beam with a Lumped Mass
Misawa Kasahara,Akira Kojima,Shintaro Ishijima 대한전자공학회 1992 대한전자공학회 학술대회 Vol.1992 No.10
In this paper, a modal analysis is applied for a hung Euler-Bernoulli beam with a lumped mass. We first derive the equations of motion using the Hamillton's principle. Then regarding the tension of beam as constant, we characterize the eigenfrequencies and the feature of eigenfunctions. The approximation employed here is corresponding that the lumped mass is sufficiently large than that of beam. Finally we compare the eigenfrequencies derived here with those obtained based on the Southwell's method.

Hiroshi Hashimoto,Masaya Ando,Katsutoshi Otsubo,Shintaro Ishijima 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
This paper considers the evaluation of several factors in Service Engineering from the view of MONOD-ZUKURI. First of all, the definition of the new trend technical term MONODZUKURI is considered in points of view from the several terms and the industrial site of Japan, and its factors are revealed. Next, by investigating the action ac-complishment of human internal, the difficulties of measuring the usability as the factors of Service Engineering is dis-cussed. Then, the admissible measurement method based on the bio-informatics is presented.
