A suspended monorail transit system is a category of urban rail transit, which is effective in alleviating traffic pressure and injury prevention. Meanwhile, with the advantages of low cost and short construction time, suspended monorail transit systems show vast potential for future development. However, the suspended monorail has not been systematically studied in China, and there is a lack o...

Due to the desire for constant improvement of the quality of passenger traffic vibration comfort has become a very important parameter when designing vehicles. Occupants are constantly exposed to vibration caused by interaction between vehicle and road vibration and whose source is in the vehicle, such as motor cars. This work is focused on the measurement of vibration due to interaction with a...

Abstract Inthispaper,anewsemi-activemagnetorheological(MR)enginemountinhalfcarmodelisproposed for improving ride comfort. Such a model uses a dynamic sliding mode controller. It operates as a controller system for controlling the magnetic field strength of the engine mount coil. Controlling the magnetic field strength leads to change the magnetorheological liquid properties and thereby the gene...

One of the main vibration problems of aerospace vehicles with liquid fuel propulsion system is fuel sloshing. This phenomenon is a low frequency vibrational challenge which can affect the motion of the vehicle and degrade the stability of the main control system. In this regards, the motion of the liquid will be very critical when the frequency of the sloshing is very close to the frequencies o...

Ground vibrations generated by heavy trucks and buses are a common source of environmental problem. They can reach levels that may cause nuisance to residents, damage to near-by structures, and perturbation in the functioning of sensitive equipment. These vibrations are produced mainly when the vehicle wheel’s pass over a speed reducer such as a road hump or a speed cushion. This study aims to ...

This paper presents an optimal vehicle and seat suspension design for a half-car vehicle model to reduce human-body vibration (whole-body vibration). A genetic algorithm is applied to search for the optimal parameters of the seat and vehicle suspension. The desired objective is proposed as the minimization of a multi-objective function formed by the combination of seat suspension working space ...
