Block Geometry page

Used to specify geometry of the block foundation

SettingDescription
Unit Select a unit of length to use for input fields on this page.
Block Dimensions Type the Length, Width, and Thickness in the selected units for the overall foundation block.
Machine Geometry (Single Block supporting Reciprocating machine only) Input the dimensions and orientation of the supported machinery.
SettingDescription
Crank Radius Type the radius of the crank.
Length of Connecting Rod Type the length of the rod connecting the crank and piston.
Crank Shaft Orientation Select which global axis along which the crank shaft (reciprocating action) is oriented.
Note: For a rotating machine, the axis the machine rotates about is assumed to be parallel to the global X axis.
Pier Geometry Type the pier Length, Width, and Thickness for each pier on the foundation block. Single Block foundations only have one pier, Combined Block foundations have two piers, and Combined Block with Gearbox foundations have three (with the third pier being in the center, supporting the gearbox). Refer to the figure in the wizard page for details.
Pier Offsets Type X and Z edge offsets from the block reference point (input on the previous page) to the nearest corner of the pier.
Note: The gearbox pier (i.e., pier 3) is necessarily the full space between the other two piers and thus does not have an offset input.
