iSTRDYN is a state-of-the-art rotating machinery mechanical design and analysis program based on two dimensional finite element theory. Some of the key features in this program are:
2D axisymmetric, harmonic finite elements with combined radial, axial, and tangential motion
Direct import of CAD files for model building
Standard support representations along with embedded rolling element and fluid film bearing mechanics
Combined steady and transient rotor dynamics, heat transfer, and stress analysis
Intuitive, integrated graphical interface with desktop, network, and Internet versions
Specific capabilities in iSTRDYN are:
Easy creation of geometrically accurate models
Models closely represent actual rotor cross-sections
Mesh defined from points & lines (from CAD file if available) or directly by specifying nodes & elements
Input and output have specific units - English, SI-meters, SI-millimeters
Advanced 2D axisymmetric harmonic elements with unlimited problem size
Axial and radial motion inherently coupled - true disk flexibility effects
Great for thin, tapered structures and overhung/cantilevered features
Solutions for zeroth and first order harmonics automatically calculated and combined
Includes plain stress elements to directly represent bladed sections
Rotor dynamics with heat transfer and stress
Nodal temperatures solved before dynamics - accurate material properties for modes & forced response
Heat transfer boundary conditions can be speed & time dependent
Damped natural frequencies including modal strain & kinetic energy
Forced response includes unbalance, asynchronous, maneuver, and time-dependent loads
Nodal stresses available from all forced response solutions
Linear and non-linear supports
Standard speed dependent linear connections (stiffness, damping, and mass coefficients vs speed)
Non-linear force-displacement for tip rubs and deadband (axial, radial, and tangential forces)
Nodal constraints
Frequency response functions in future release
Embedded fluid film and rolling element bearing mechanics
Specify geometry and lubricant, program determines deflection at bearing iteratively
Rolling element model considers ball and roller bearings, solves hertzian contact with traction effects
Fluid film model includes journal bearings, squeeze films, tilt pads, and hydrostatic bearings
Complete set of graphical displays and text listings
Geometry, deformed, and contour plots
Complete user control of boundary conditions and load displays
Whirl maps, stability maps, and mode shapes
Nodal displacements, support loads, and temperatures versus speed or time
Mode shapes and deformed mesh can be animated (and exported)
Time histories, orbits, and FFT spectra
General and context-sensitive help system
All plots and listings can be saved in standard graphics or text files
Model, material properties, and lubricants imported/exported using XML files
