摘要
现如今,中国已成为世界第三国际贸易大国和第一大集装箱制造国。但是随着工业生产的需求,造成热带雨林逐年减少,克隆木(apitong)已成为稀有树种,生产集装箱木地板所用的原材料也由进口材克隆木逐渐向多材种方向发展。在此情况下,寻求替代进口材克隆木的新材料,并研究其用于集装箱木地板受外部强度作用后损伤(破坏)的机理尤为重要。本文通过对集装箱木地板7260 kg小车试验与常规实验室载荷试验的力学分析与比对,对集装箱木地板开层的原因及开裂位置进行研究,阐明了集装箱用木地板在外部强度作用下的形式与机理。
Today,China has become the world's third largest international trading country and the largest container manufacturer.However,with the demand of industrial production,resulting in the decrease of tropical rain forest year by year,clonal wood(apitong)has become a rare tree species,and the raw materials used in the production of container wood flooring have gradually developed from imported clonal wood to multi-timber.In this case,it is very important to find new materials to replace imported clone wood and study the mechanism of damage(destruction)of container wood flooring subjected to external strength.Based on the mechanical analysis and comparison of 7260 kg container wood floor test in trolley and conventional laboratory load test,the causes and cracking position of container wood floor opening were studied,and the form and mechanism of container wood floor under the action of external strength were clarified.
