Design, Construction and Evaluation of grain harvester combine’s header loss based on statistical analysis and modeling the optimal factors
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
This study was conducted to evaluate the efficacy of grain harvester in wheat field, in the West Azarbaijan province of Iran. Efficacy was accessed in both lab and field test, where as lab test included CATIA, V5 R21 design. Data from the sensor and wooden frame were utilized forstatistics analysis. Moreover, the effects of forward speed of combine (Vc) and peripheral speed of reel ?s tip (Vr) were also studied on header loss (reel index= Vr/Vc). Statistical analysis study was conducted by the Factorial analysis of variance with randomized complete block design32 (whereas equipments 1 , 2 were considered as blocks and 4 replications for each blocks), with the help of SPSS19 software. The result of the Duncan?s test found that the differences between means of two trails are significant at 5% probability level. Paired samples test was used to compare mean between header loss data that have been obtained from wooden frames and two systems, results of study revealed 1.6 and 0.78 reel index (RI). Duncan ?s test found that the difference between means of two equipments and wooden frame is not significant. In response surface method, central composite design was used to modeling and finding optimal levels of mentioned factors; at the optimum condition, minimum combine header loss were reported1.1 for RI.
