Based on the characteristic of a type of commercial vehicle, a multi-body model of its full suspension system with twenty Degree of Freedom (DOF) was established in MSC.ADAMS. After evaluating relative condition parameters such as stiffness and damping index on the simulation model, the effects of outside exciting on the suspension system have been worked out numerically. The harmonic response ...

one of the new methods for electrical powering of the bridge health monitoring systems is applying energy harvesting systems using bridge vibration. in this method, the piezoelectric material is employed for converting mechanical energy into electrical energy. the advantage of this method is based on not implementing the battery charging system. in previous research, some studies have been done...

This paper presents the initial results of a study aimed at improving the method by which the vibrations produced by transport vehicles are characterised and simulated. More specifically, this paper focuses on the rigid body vibrations generated by road transport vehicles in the context of distribution of packaged goods and produce. The research uses a variety of vibration data, collected from ...

T H I S P A P E R is a review of the problem of noise and vibration with respect to manned space flight. For the purposes of this discussion, noise will be defined as the energy transmitted to a man through the air at all frequencies up to 15,000 cps. Vibration will be defined as all of the energy transmitted to a man through the structural components for all frequencies above 0.5 cps. The sepa...

high speed trains are an indispensable part of rapid transportation systems in many countries. as the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

A stochastic model of traffic excitation on bridges is developed assuming that the arrival of vehicles traversing a bridge modeled as an elastic beam follows a Poisson process, and that the contact force of a vehicle on the bridge deck can be converted to equivalent dynamic loads at the nodes of the beam elements. The parameters in this model, such as the Poisson arrival rate and the stochastic...

According to the structure characteristics of railway viaduct with light floating slabs, a frequency domain dynamic model of the vehicle-light floating slab track-viaduct bridge vertical coupling system is established. The Green functions are used to quickly calculate the receptance response of the system, and then the pseudo excitation method is used to further analyze the parameter influences...

The development of structural health monitoring systems for bridge structures necessitates improvements in the understanding of vehicle-bridge interactions. Direct measurement of the complex coupling that naturally exists between vehicles and bridges is a challenging undertaking due to the limitations of existing sensor technologies. However, the emergence of wireless sensors in the field of st...

Rubber bushings are extensively-used linking parts in a vehicle chassis that allow to filter noise and vibration. They influence much, however, the transient behaviour of the vehicle, such as its steering performance. Therefore building a multibody simulation with a relevant description of the rubber bushings is useful to describe the significant characteristics of the vehicle’s steering behavi...
