Backgrond and aims: Due to the rapid development of agricultural mechanization operations and the use of tractor as one of the most important agricultural machinery, focus on the health, ergonomic and safety working conditions of the tractor operators is a MUST. Methods: In this research the impact of BMI index and the leg angles of Iranian common tractors drivers on pain threshold reduction...
the directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindrical tank, are investigated in various maneuvers. the dynamic interaction of liquid cargo with the tractor semi-trailer vehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom of a tractor semi-trailer tank model. ...
in this paper a survey to determine the spring and damper settings of itm285 tractor’s cabin which ensured optimal ride comfort of tractor operator was conducted. analysis has been done in terms of root mean square acceleration response (rmsar) in one-third-octave band and international standard organization (iso). optimization was performed using particle swarm optimization (pso) method on a 2...
Measurement of the values of forces in tractor arms is of great importance due to draft of agricultural equipment. These values can be used for testing and evaluation of the agricultural machinery, selection of suitable tractor, etc. The tools which are used for measurement of the forces are called dynamometer. The main objective of the present study was to design and evaluate a load cell for i...
Sugarcane is one of the severely perishable crops that is used as raw material for white sugar production. Sucrose content of the sugarcane which is of high commercial value decreases in quality due to pre-harvest burning, high ambient temperature, kill-to-mill delays as well as microbial contaminations. Delays in sugarcane transportation are the most important risks which can affect the qualit...
We propose a tractor atom interferometer (TAI) based on three-dimensional (3D) confinement and transport of split atomic wavefunction components in potential wells that follow programmed paths. The paths are to recombine wavefunctions at well-defined space-time points, guaranteeing closure the interferometer. Uninterrupted 3D interfering eliminates coherence loss due wavepacket dispersion. Usin...
