本文介绍了两种单斗液压挖掘机工作载荷谱数据采集及数据分析处理的方法。对于挖掘机的载荷(应力)时间历程的分段记录;频次的合成与扩展;样本长度等问题都结合单斗液压挖掘机自身特点和载荷谱试验过程中的具体情况提出了新的体会和看法。
This paper introduces the data acquisition and data analysis and processing methods of two kinds of single bucket hydraulic excavators. Segmentation records of the load (stress) time history of the excavator; frequency synthesis and expansion; sample length and other issues have combined with the unique characteristics of the single bucket hydraulic excavator and the specific conditions of the load spectrum test process to put forward new experiences and views .
