dc.description.abstractThe main purpose of this thesis is to analyze the forced damped single degree of freedom vibration of Chery100hp tractor transfercase. The tractor which assembled at AAMI.An appropriate mathematical modeling, field measurement,response on harmonic excitation of the transfer case by means of ANSYS 17.2 were performed to identify the critical frequency, to know whether the natural frequency calculated through mathematical analysis fall on the range of critical frequency or not and to identify the high vibration speed zone on the particular tractor. The general solution found in mathematical modeling imported to MATLAB to generate results. The recorded value calculated by Random velocity calculation method and compared with ISO General Standard (10816-1:1995).3D modeling of transfer case made by using CATIA V5 and imported to ANSYS 17.2 for modal analysis. According to the analysis the SAE 140 has significance effect on 100hp but negligence effect on 95 hp. The comparison calculated natural frequency value of the current transfer case with critical frequency analyzed harmonic excitation indicates that the natural frequency found to be 5063.05 rad/sec or 805.8Hzwhile the critical frequency fall on the range between (825-875) Hz. This natural frequency is in the same range (500-3500) Hz as experimental analysis obtained by Jiri Tuma (2009).The measured vibration velocity value of eight speed zone condition was calculated and comparedwith ISO as a result bad vibration zone was identified.en_US
