Notes About Dependent/Independent Suspension Curves
The suspension analysis dialog box calls an analysis submission macro that executes the generate_scf.exe utility using a system command. The generate_scf.exe utility creates suspension characteristics files (scf) by reading and extracting data from different request files. The amount of information written to the scf file depends on the number and type of request files it finds in the working directory. It also creates a log file that lists warnings and execution errors.
After the dialog box successfully completes the analyses, it copies the generated suspension characteristic file to the suspension_curves.tbl directory in the
Default Writable Database. It also leaves a copy of the scf file in the local working directory for future examination.
You can also invoke generate_scf.exe from the command line as a stand-alone utility:
generate_scf.exe output_prefix_scur flag
where:
■output_prefix_scur identifies all the different requests
■flag identifies whether the suspension is independent or dependent
The generate_scf.exe utility uses one of the .nam files, that Adams Car creates, as the key to determine the request ID corresponding to a given result name; to successfully execute generate_scf.exe, the name file *_pw0.nam must be in the working directory.
The type of results and components that generate_scf.exe is looking for in the different requests is predetermined, and you cannot change it. It relies on the definition of the suspension characteristic requests as they are formulated in the .__MDI_SUSPENSION_TESTRIG.
Dependent and independent suspension curves are very different. Adams Car does not know if your suspension is dependent or independent. It is up to you to use the appropriate dialog box that generates suspension curves.
