Abstract

In order to evaluate the safety and comfort of trains for highspeed multiline railway

bridges

it is necessary to perform a simulation research on coupled vibrations for multiline railway

vehiclebridges. For this study

the threedimensional space dynamic models of CRH3 motor car and

trailer were set up using a multibody system dynamics software SIMPACK

and the train dynamics

model was assembled via the established CRH3 motor and trailer model by the substructure technology

of SIMPACK. The dynamic analytical model of bridge was established by using finite element software

for calculating the natural characteristics. Then

according to the deformation compatibility

condition and force balance condition between the train system and bridge system

the data transfer of

the displacement and force on the wheelrail contact surface was conducted. The simulation study of

multiline vehiclebridge coupled vibrations was carried out by cosimulation based on SIMPACK and

ANSYS for the first time. Meanwhile

the dynamic indexes of the bridge

comfort indexes

and safety

indexes of the train were analysed to explore the general rules and influences of coupled vibrations on

multiline vehiclebridges. The research results are as follows

:(

The corresponding vehicle safety

indexes

derailment coefficient

wheel unloading ratio

and wheel / rail lateral force

under the

combined action of three line trains are almost the same as those only under single line action. As for

the vehicle comfort indexes

vertical body acceleration

lateral body acceleration

vertical comfort

index

and lateral comfort index

),

most of the corresponding indexes under single line and three line

action are very close

within 1% difference

),

the only exception being individual vertical body

acceleration with slightly larger difference

about 10%

between them. Hence

these comparisons

show that the influence of bridge vibrations on the dynamic indexes of trains is small owing to the great

stiffness of bridge structures. Thereby the values of corresponding dynamic indicators between single

line condition and multiline condition are very close

i. e. the dynamic indexes of vehicles under

multiline conditions can be speculated by those under single line conditions.

The midspan vertical

displacement under the combined action of three lines is slightly larger than the algebra superposition

displacement of single line

but less than 1%

and the influence coefficient of vertical displacement is

between 1. 001 - 1. 006. The midspan lateral displacement under the combined action of three lines is

close to the single line superposition displacement with about 10% difference

and the influence

coefficient of vertical displacement is about 1. 000. Therefore

the midspan vertical and lateral

displacements under the multiline condition can be speculated by superposing all single lines.

The

absolute value of midspan vertical acceleration under the action of three line trains is smaller than that

of algebraic superposition for single lines with influence coefficients between 0. 636 - 0. 771

hence

it

is feasible to conservatively evaluate the vertical acceleration of a bridge under multiline condition

referring to the superposition of all single lines. The absolute value of midspan lateral acceleration

under the action of three line trains is smaller than the maximum value among the absolute values of the

lateral accelerations of each single line

thus

the lateral acceleration of a bridge under multiline

condition can be evaluated referring to its single line lateral acceleration.

VRP is an NP-hard problem [7]; heuristics and evolu- tionary algorithms are used to solve VRP. In this paper, mutation ant colony algorithm is used to solve MRVRP with

In order to study the rheological characteristics of magnetorheological fluids, a novel approach based on the two-component Lattice Boltzmann method with double meshes was proposed,

A characterization of quasi r*-invariant measures on metric to- pological semigroups is obtained by showing that their support has a left group structure thus generalizing
