JNTUK B.Tech Vehicle Dynamics gives you detail information of Vehicle Dynamics R13 syllabus It will be help full to understand you complete curriculum of the year.
Objectives: To import knowledge of various kinds of vibrations caused due to different aspects like road construction, engine unbalance and vibration measuring techniques.
Unit-I : Undamped free vibration: Single degree of freedom Systems, introduction, undamped free vibration -Natural frequency’ of free vibration, Rayleigh’s method, stiffness of spring elements, effects of spring mass, Energy method, Newton’s method and D’ Alembert’s principle- problems.
Unit-II : Damped free vibration: Single degree of freedom systems, different types of damping, concept of critical damping and its importance, response study of viscous damped systems for cases of under damping and over damping, logarithmic decrement.
Unit-III : Forced vibration: Single degree of freedom systems, steady state solution with viscous damping due to harmonic force solution by complex algebra, concept of response, reciprocating and rotating unbalance, vibration isolation Transmissibility ratio, energy dissipated by damping equivalent.
viscous damping. Structural damping, sharpness or resonance. base excitation.
Unit-IV : Systems with two degree of freedom: Introduction, principle modes and normal modes” co- ordinate coupling, generalised and principle co-ordinate, free vibrations in terms of natural conditions. Lagranges equation, semi-definite systems, forced oscillations. harmonic excitation.
Unit-V : Vehicle vibrations: Vehicle vibration with single degree of freedom free vibration, forced vibration, vibration due to road roughness, vibration due to engine unbalance, transmissibility of engine mounting vibration with two degree of freedom, free vibration, compensated suspension systems forced vibration, vibration due to road roughness. Vibration measuring instruments Accelerometers and vibrometers. whirling of shafts with and without air damping, discussion of speeds above and below critical speeds.
Unit-VI : Numerical methods for multi degree of freedom systems: Introduction, influence coefficients, Maxwell’s reciprocal theorem, Dunkerley’s equation, orthogonality principle, method of matrix iteration- method of determination of all the natural frequencies using sweeping matrix and orthogonality principle, Holzer’s method for systems with free, fixed free and fixed ends.
Course outcome: After completing the course the student will be in a position to use various methods and techniques to minimize the vibrations caused during the operation and running of vehicles.
