摘　　要：龙门起重机广泛应用于伐木场和木材转运站等场所的木材装卸作用中。而对于林用起重机的开发研究,采用原型试验分析受到时间、实验条件等诸多限制。运用相似理论和量纲分析法,采用模型分析研究,既降低了风险和成本,又提高了工作效率。Forest gantry crane was widely used sawmill and timber transfer stations and other places in log loading and unloading.For the crane development researches,the prototype test analysis was restricted by time,experimental conditions,and many other factors.By using similarity theory,dimensional analysis,and model analysis research,the researches’ risk and cost were reduced,and the work efficiency also was raised.
