Engine Ports

[AETelliot]

Can anybody provide the best method formodelling inlet/exhaust ports of a 4-stroke engine. I would like to have sectional shape control along with cross sectional area control. Currently I use the variable section sweep to model the port which gives good control on shape, but does not allow area control. The use of swept blend provides area control but not the level of sectional control that I need or is provided with variable section sweep.


Many Thanks


I hope somebody can help

Link the VSS section to an eval graph function. May get what you want.


Posting something to work with will be more productive than attempts at verbal communication.

AEtelliot,


You can use surface by boundary thenyou can control the area by creating series of area curves atdesignated locations...hope it helps...

Thanks for the replies.


Unfortunately I cannot post pictures etc due to confidentiality. I think I will use the boundary blend feature and define a lot of sections in between the start and end of the port.

"...I think I will use the boundary blend feature and define a lot of sections in between the start and end of the port."


As a general rule:Over defined surfacesare abad idea tho' it may be the most expedient way to get "something".


Can you post a hypothetical start and end section or something that represents what you are trying to do anda development criteria? It might be fun to play with.
