Última Models for crop parameters due to normal load of tractor and number of passes CIGR Journal Patel, Sanjay Kumar; Mani, Indra; Gupta, Pankaj; Srivastava, Akhilendra P.; Sundaram, Prem K.. Multiple passage of power machinery system particularly heavy machines with high wheel loads creates sub-soil compaction which results into increasing in soil bulk density & penetration resistance and reduction in water infiltration, crop germination, growth as well as yield. This study was conducted to determine the different crop growth and crop yield models could be developed to predict growth as well as yield of crop considering normal load and number of passes of tractor. A 36-plot experiment consisting of 12 treatments with three replications were set up using a randomized block design in a uniform field of Division of Agricultural Engineering, IARI, New Delhi during the period of 2007-08. Prediction models were developed between compaction... Tipo: Info:eu-repo/semantics/article Palavras-chave: Sub-soil compaction; Wheel trafficking; Normal load; Yield and crop model. Ano: 2021 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/7105 Prediction Of Lateral Force In An Off-Road Tire As A Function Of Seven Variables Using Response Surface Methodology (RSM) CIGR Journal Abdolmaleki, Hamid; Jafari, Ali; Mousazadeh, Hossein; Hajiahmad, Ali. In this study an in-situ Single Wheel Tester (iSWT) was used to investigate the effect of some of the most important independent variables on the lateral force of a high lug agricultural tire. The variables include some soil parameters and tire characteristics. Response Surface Methodology (RSM) also was used to construct a design of experiment and propose the lateral force model as a function of seven variables (various combination treatments of soil characteristics and tire parameters). A total of 152 experimental tests were conducted to find appropriate model. Reduced form of a quadratic model was selected to predict the tire lateral force (R2 > 0.9). The results show that the side slip angle and moisture content had major and minimal effect on tire...
