A optimizacao da utilizacao do tractor 2RM em traccao

Full scale field tests show that Gee-Clough model is suitable for traction on wet clay soils on the Instituto Superior de Agronomic farm located at the Tapada da Ajuda, particularly when Cone Index measured at 150mm depth (C_150) is used. Numerical analysis of the standard driving tyres (A8*) at maximum loads for fields speeds up to 30 km/h, gave a more simple form for mobility number as R_M*=0.01 C_150. Typical values for tractor driving wheels performance parameters as a function of the soil conditions (C_150) is presented in a form of a table, performed by the simplified model equations. The appropriate methodology for optimizing the tractive performance of 2WD agriculture tractor matching the mechanics of the vehicle provided by O.C.E.D. test code against the mechanical soil/tyre behaviour defined by the tabulated values was developed and applied to a workable exampleAvailable from Fundacao para a Ciencia e a Tecnologia, Servico de Informacao e Documentacao, Av.
