A comprehensive look to the universal self-propelled rice transplanters using Analytic Hierarchy Process (A case of developing country) CIGR Journal
Allahyari, Mohammad Sadegh; Firouzi, Saeed; Pourrahman, Bahram; Marzban, Soroush.
The main purpose of this study at the first phase was to rank all rice transplanters used in Guilan Province by relevant experts in the area from technical, social, and economic aspects. After the most appropriate type was identified, the technical skillfulness of operators to use this specific type was assessed in the second phase. To this end, the analytic hierarchy process (AHP) was applied and the opinions of experts for exploring the most appropriate rice transplanter based on ergonomics, economic advantage, reliability, field capacity, ease of use, ease of repairs and access to spare parts, compatibility with plot conditions, planting density range,  compatibility with different soil conditions and planting quality perspective was assessed. To...

APPLICATION OF OPTICAL METHOD IN MEASURING MECHANICAL VIBRATIONS IN A CANTILEVER BEAM REA
Silva,Marcos V. G. da; Fabbro,Inácio M. Dal; Lino,Antônio C. L..
ABSTRACT The pertinent literature discloses a family of optical profile measuring techniques highlighting the moiré methods. The Moiré technique is based on the interference of two superimposed optical grids which produce fringe patterns which can be processed to analyze the DYNAMIC MEASUREMENT IN MATERIALS mechanical behavior. The goal of this research is to experimentally determine the mechanical displacement of a slim cantilever beam by means of Moiré technique with Phase Shift. Photomechanical experimental arrangement included a digital camera, a multimedia projector and a PC. The occurrence of oscillations has been adequately analyzed. The results showed data from which useful information can withdraw, being of great importance to support agricultural...

Design and selection of agricultural machinery using a quality function deployment technique CIGR Journal
ARUDRA, ASHOK KUMAR.
The demand of agricultural machinery has been increasing day by day due to lack of availability of human power and increasing the cost of cultivation. The agricultural machinery development is hundreds of time what they were several years ago. The growth of agro industry depends on the farmers; so the production of farm products must be based on farmer’s requirement. Even though they are producing required products still there is a gap between farmers and designers. The most agricultural machinery operator having suffered injuries on shoulder, wrist and elbow, most researchers have concentrated their attention on propelling efficiency or biomechanics issues, not operation interface based on operator s’ requirements. Though some innovative changes have been...

Factor analysis of agricultural mechanization challenges in Iran CIGR Journal
Bagheri, Nikrooz -; Bordbar, Marziyeh.
A descriptive survey research was undertaken in order to assess challenges facing agricultural mechanization development in Iran.  The research population included agricultural mechanization experts, managers and specialists in private and governmental sections.  Using proportional stratified sampling, a sample of 119 was constituted out of a total population of 809 based on the Cochran formula.  Data were collected using questionnaire on which the statements were collected after literature review of research and interviews with mechanization specialists.  The questionnaire was validated by a panel of experts and its reliability index was established by a Cronbach’s coefficient.  A pilot study was conducted with 30 questionnaires (not included in the...
