Novel draught resistance sensing elements for measurement of drawbar power of agricultural machinery
نویسندگان
چکیده
Aim of study: To develop an instrumentation system comprising three force sensing elements to measure the draught resistance any tillage and seeding tools during field operation by connecting one element each three-point linkage tractor.
 Area Department AgFE, Indian Institute Technology, Kharagpur, India
 Material methods: Commercial S-type transducers were packed laterally in between curved plates perpendicular direction travel such a way that magnitude imposed decreased its nature got reversed consequently measurement. Finite analysis was also performed on proposed model elements. The performance evaluated basis non-linearity, hysteresis, non-repeatability. data validated with values simultaneously recorded using instrumented linkages Main results: It offered good sensitivity linearity static calibration. measurement capacity based maximum applied load calibration 10 kN accuracy 93.40%. low mean percentage error (9.03%), absolute variation (17.43%), root square (0.51 kN) revealed system. Validation conducted comparing for offset type disk harrow outputs previous studies assess suitability other soil working conditions, results satisfactory.
 Research highlights: advantages this device drawbar power are fewer changes hitching geometry, lower cost, capability quick hitching.

Ultrasonic horn with transfer of acoustic wave into an aqueous solution results in unique properties. When, transfer of sound wave into a liquid results in liquid movement in the direction of wave propagation which gradually loses its energy due to the viscous friction. This wave motion induces a flow which is known as acoustic streaming or micro-streaming. In this article, a simple innovative ...
