Change the material of th disque and the shaft

Hi every one ;

I'm just wanna ask you please, about including in a matlab code the change of matérials of the shaft and the disc, the bearing characteristics!!

even the unbalance.

nd thanks in advance !!

Hi @Amira,

I assume you want to know how to programmatically change material properties of certain Simscape blocks. The ‘get_param’ and ‘set_param’ functions can be used to access and modify the parameters of Simulink and Simscape blocks. Here’s some documentation for these functions:

1. ‘get_param’: https://www.mathworks.com/help/simulink/slref/get_param.html
2. ‘set_param’: https://www.mathworks.com/help/simulink/slref/set_param.html

For example, to change the material parameters of the ‘Flexible Shaft’ block, we’ll first need to choose the parameter to change from the list obtained using the following ‘get_param’ command:

get_param('Model/Flexible Shaft', 'DialogParameters'); 

‘Flexible Shaft’ parameters documentation:

https://www.mathworks.com/help/sdl/ref/flexibleshaft.html#mw_4b424d3d-3718-4881-8b04-ca2df84d1287

Then the ‘set_param’ command can be used to change the value of the parameter (for example ‘density’). Note that, in the documentation it is mentioned that a prerequisite to change the ‘Material Density’ parameter is to change the ’Parameterization’ parameter to ‘By material and geometry’ or ‘By material and segment geometry’.

set_param('Model/Flexible Shaft', 'density','5'); 

Similarly, other material parameters can be changed for different Simscape blocks.
