“…The ride comfort of TW vehicle with Conventional suspension was studied by Sharma et al and it was concluded that as per ISO comfort specifications, their ride lies inside 1-h comfort boundary. [5][6][7][8] Researchers also investigated the stability and handling capabilities of TW vehicles and suggested certain design modifications.…”

Three-wheeled vehicles may be a better choice as compared with four-wheeler cars provided they are properly designed to improve the rollover stabilities and ride comfort. The design modifications need improvement in geometry and suspension. This article presents the dynamic behavior of three-wheeled vehicle equipped with an inerter-based dynamic absorber and compares the same with the conventional suspension system. The performance parameters analyzed are vertical-lateral acceleration, front & rear suspension deflection, and front & rear dynamic tyre loads. The analytical rigid body model is formulated by assigning 9 degrees of freedom to the system for the evaluation of performance parameters to compare the inerter-based absorber suspension with the conventional passive suspension system.

“…The equations of motion (EoM) for the biodynamic human body model have been formulated in past. 13 In past, a LP (Lumped Parameter) biodynamic human body model in sitting posture is developed 14,15,16 and formulated its differential EoM. This model consists of six rigid bodies namely, leg, pelvic, viscera, upper torso, vertebral column and head.…”

Under low-frequency excitation, the human subject is highly sensitive to Whole Body Vibrations (WBV). In the present paper, a biodynamic human model is seated posture without backrest support and also with backrest support at different angles (i.e., 0°, 15° and 30°) is formulated to analyse the influences of the frequency and the magnitude of the vibration, backseat support and the angles of inclination of the backseat support on Seat To Head Transmissibility (STHT) of the biodynamic human subject in seating position exposed to WBV. The model parameters such as damping, mass and stiffness of the mathematical model considered in this paper are derived from an alternate methodology which is based on anthropometric data. The STHT is computed analytically with the help of MATLAB software for all the considered cases. The effect of vibration and excitation frequencies on STHT is analysed. The results of STHT evaluated from this work are justified by comparing the same with the mean STHT characteristics reported in past studies and the results of the present analysis come out to be in good agreement with past published research.

“…Recent studies suggest that optimization design based on being lightweight may decrease cost, reduce the force between wheel and rail to protect them, achieve energy savings, and reduce emissions [3][4][5][6][7][8][9][10]. The stochastic vibration is obtained at the structure because the CB is adversely affected by track irregularities and wind pressure while the vehicle is moving.…”

This paper examines the influence of the equipment considered as a DVA (Dynamic Vibration Absorber) upon the mode of vertical vibrations of the car body in high-speed vehicles. The car body is represented as an Euler-Bernoulli beam to minimize flexible vibration. The DVA approach is used to find the appropriate suspension frequencies for various types of equipment. A vertical mathematical model with a flexible car body and equipment is developed to investigate the effect of equipment mass, suspension stiffness, damping, and mounting location on car-body flexible vibrations. A three-dimensional, rigid-flexible coupled vehicle system dynamics model is developed to simulate the car body and equipment’s response to track irregularities. The experimental result was considered to verify the theoretical analysis and dynamic simulation. The mathematical analysis demonstrates that the DVA theory can be used to design the suspension parameters of the equipment and that it is suitable and effective in reducing the flexible vibration of the car body in which the vertical bending mode is greatly affected. Heavy equipment should be mounted as close to the car body’s center as possible to achieve significant flexible vibration reduction, whereas light equipment contributes very little flexible vibration reduction.
