Some researches have been made for cultivating and producing short rotation trees as an energy source. Woody biomass such as willow or hybrid poplar is grown in European and North American countries. In that area, sugarcane harvester is used for harvesting woody biomass production. While in the south-west islands of Japan, sugarcane is grown as one of the main crops and many harvesters are used. Also, considerable area is expected for woody biomass production. There should be big potential to grow short rotation trees for energy source in that area under the subtropical climate. In this study, the production possibility of woody biomass in south-west islands of Japan is discussed. For testing the adjustability with the sugarcane production, the cutting resistances of some selected species were measured using the cutting knife of the sugarcane harvester."},{"@language":"ja","@value":"奄美地域を初めとする南西諸島においてはサトウキビが基幹作物として生産されている.これらの地域は気候条件や現有の機械設備の状況から判断して,木質バイオマスを生産するのにふさわしいと考えられる.本研究では,奄美地域での木質バイオマスの収穫機構の開発を目指している.そのための第一段階として,ケーンハーベスタを利用した木質バイオマスの切断機構に関する基礎実験を行った.まず,亜熱帯地域に適応性の高いと考えられる5種類の樹種について静的な切断抵抗を測定した.その結果,供試した樹種のうちアカギが最も小さな切断応力を示した.そこでアカギならびに比較のためにサトウキビを用いて実際の収穫時の切断速度に近い速度での切断抵抗測定実験を行った.切断角度を0°と30°の2種類について測定したところ,角度を大きくした30°のの方が最大切断応力はアカギ,サトウキビの両方について4割程度小さくなることが示された.また,切断に要する時間を比較したところ切断角を0°から30°にすることで切断時間が長くなることが示された.その理由は,刃部での材料の進行距離が長くなること,また,刃縁に沿って材料がすべりを起こすこと等にあると推察された.切断角度が大きくなると,スムーズな切断が進行するため衝撃的な力が作用しにくくなるものと考えられ,切断角度は,切断のメカニズムに大きな影響を与えることが明らかになった."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1030003658571939586","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"90232652"},{"@type":"NRID","@value":"1000090232652"},{"@type":"NRID","@value":"9000005125252"},{"@type":"NRID","@value":"9000256692791"},{"@type":"NRID","@value":"9000256695074"},{"@type":"NRID","@value":"9000256702376"},{"@type":"NRID","@value":"9000256690741"},{"@type":"NRID","@value":"9000256701293"},{"@type":"NRID","@value":"9000002224922"},{"@type":"NRID","@value":"9000252923215"},{"@type":"NRID","@value":"9000256690146"},{"@type":"NRID","@value":"9000256702974"},{"@type":"NRID","@value":"9000024956432"},{"@type":"NRID","@value":"9000399004879"},{"@type":"NRID","@value":"9000004008812"},{"@type":"NRID","@value":"9000256695343"},{"@type":"NRID","@value":"9000256691985"},{"@type":"NRID","@value":"9000253684997"},{"@type":"NRID","@value":"9000256694720"},{"@type":"NRID","@value":"9000256691606"},{"@type":"NRID","@value":"9000003623873"},{"@type":"NRID","@value":"9000256693033"},{"@type":"NRID","@value":"9000256703586"},{"@type":"NRID","@value":"9000255908464"},{"@type":"NRID","@value":"9000255906394"},{"@type":"NRID","@value":"9000256693985"},{"@type":"NRID","@value":"9000007095623"},{"@type":"NRID","@value":"9000283273980"},{"@type":"NRID","@value":"9000256708624"},{"@type":"NRID","@value":"9000256695329"},{"@type":"NRID","@value":"9000256694556"},{"@type":"NRID","@value":"9000255906398"},{"@type":"NRID","@value":"9000256695338"},{"@type":"NRID","@value":"9000022184003"},{"@type":"NRID","@value":"9000255908248"},{"@type":"NRID","@value":"9000256693922"},{"@type":"NRID","@value":"9000256694272"},{"@type":"NRID","@value":"9000256714865"},{"@type":"NRID","@value":"9000253684744"},{"@type":"NRID","@value":"9000256693918"},{"@type":"NRID","@value":"9000256693038"},{"@type":"NRID","@value":"9000297506568"},{"@type":"NRID","@value":"9000252923259"},{"@type":"NRID","@value":"9000256692029"},{"@type":"NRID","@value":"9000391753913"},{"@type":"NRID","@value":"9000017339791"},{"@type":"NRID","@value":"9000323298977"},{"@type":"NRID","@value":"9000256694715"},{"@type":"NRID","@value":"9000256693043"},{"@type":"NRID","@value":"9000256706833"},{"@type":"NRID","@value":"9000256710102"},{"@type":"NRID","@value":"9000256714860"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0017797"}],"foaf:name":[{"@language":"en","@value":"IWASAKI
