摘要
介绍了装载机前视野的设计准则、物元可拓法的基本原理及计算步骤,同时将可拓学原理应用于研究装载机前视野水平的综合评定。建立了装载机前视野水平评定的物元模型,并以实例说明了可拓学理论的应用为评价同类问题提供了一种创新的、实用的定量分析思路。此外,提出用简单关联函数确定指标权重,克服了人为因素的影响,使得评定结果更客观,更具有参考价值。
Standard for the the forward visibility of a loader,basic theory and calculating proces of matter-element extension was introduced,in the meanwhile,extenic theory was applied to evaluate the level of forward visibility of a loader.Matter-element model was established and a example was given to illustrate that the application of extenic theory provided a creative and useful evaluation method for quantitative nalysis of the same kind.Furthermore,weight of factors is determined using simple dependent function to avoid the effects of human factors,which is of considerable objective evaluation and referential importance.
