課程大綱
 

1 1A Description of Actran workshop

1 To import an ACTRAN input file and check the content of it

2 To export both the mesh and the input file

3 To launch in different ways the input file

2 1B-1 Example of sound source in a treated cavity(foam layer)

1 One considers the same cavity as in workshop 1A but one layer of fluid elements is replaced by a foam layer

2 Sound in enclosure: a spherical source is placed in one corner of a 1m3 cavity wuth 5 rigid walls and a foam layer

3 A 0.125m thick foam layer is glued against one of the cavity walls(from y=0.375m to y=0.5m)

4 Use rigid porous elements

3 1B-2 Training of Kundt's tube

1 Problem description and models

2 Workshop description

3 Using BOXPRO as a pre-processing tool

4 1C Using equivalent admittance

1 One considers the same cavity as in previous workshop

2 The spherical source placed in one of the box corner at (x,y,z)=(-0.375,-0.375,-0.375)

3 Use an admittance boundary condition for modeling the foam

4 Computed results(compare with workshop 1A)

4.1 The mean square pressure amplitude from 1Hz to 500Hz

4.2 The sound pressure level at the center of the box

4.3 Plot a color map at 295Hz

5 2 Model extraction: acoustic cavity

1 One considers a 1m3 cavity, centered on the origin(0,0,0)

2 One considers default air properties for the fluid and assumes the walls to be rigid

3 Use quadratic, 0.125m sized elements

4 Post- processing:

4.1 Extract the modes in the 1Hz to 500Hz frequency range

4.2 Plot a color map of 7th mode(order(m,n,l)=(1,1,1)) and compare it with the workshop 1A map

6 3 Free field radiation of a monopole

1 Purpose: free-field radiation of a monopole in air at standard conditions

2 Plot the real part of the pressure from 1Hz to 500Hz measured at (x,y,z)=(1,0,0)

3 Plot the sound pressure level from 1Hz to 500Hz measured at (x,y,z)=(1,0,0)

4 Visualize a map using cutplanes functions

7 4 Duct radiating in free field

1 One considers a simple duct radiating in a half free space

2 The duct is excited with each mode propagating at 700Hz

3 Compute the pressure variation along the duct axis

4 Plot a color map

8 5A BC_MESH application: structure radiating in a free field

1 The objective of this workshop is to evaluate the acoustic radiation of a simple vibrating structure

2 The parameters of the problem

3 The displacement of the edges of the panel are set to 0

4 The excitation is displacement at the center of the plate

9 5B Training

1 The objective of this document is to explain how to create an ACTRAN model in order to compute the acoustic radiation of a vibrating structure

2 This training is based on a gearbox model

10 6 Visco-thermal effects in Actran

1 Visco-thermal elements in Actran

2 Purpose: understand the visco-thermal effects occurring in a thin circular tube connecting to acoustic cavities

3 Plot the SPL of the pressure from 10Hz to 3000Hz measured at (x,y,z)=(0.05,0.6,0) for 2 cases: with and without visco-thermal effects in the thin tube

4 Plot the average SPL in the different cavities

5 Visualize pressure maps at some frequencies of interest
