Overview

The CAEfatigue Frequency Package is a specialized software module developed by Hexagon to perform random response and fatigue analysis in the frequency domain. It is designed to handle multiple simultaneous correlated load inputs across various degrees of freedom (DOFs), inputs, events, and frequencies. This capability enables engineers to predict fatigue life and damage under complex loading conditions, making it a powerful tool for durability analysis in engineering applications.

Features and Capabilities

• Comprehensive Fatigue Analysis: Performs S-N (Stress-Life) and E-N (Strain-Life) fatigue calculations, supporting both stress-life and strain-life methods.
• Advanced Load Handling: Processes multiple random input Power Spectral Densities (PSDs) and cross-PSDs with mean offsets, accommodating data from test rigs with multiple events and channels per event.
• Mean Stress Effects: Incorporates mean stress effects using various criteria, including Goodman, Gerber, Morrow, SWT, Walker, and MMPDS, to enhance fatigue life predictions.
• Collision Detection: Assesses collision probabilities (rattle) between parts, aiding in the identification of potential interference issues in assemblies.
• Load Cascading: Transmits loads from input locations to internal locations within the model, facilitating comprehensive internal load analysis.
• Enveloping Functions: Develops enveloping functions to simplify testing procedures, streamlining the analysis process.
• Load Conditioning Toolkit: Reduces test durations by conditioning loads, optimizing the testing phase.
• Notch Functionality: Simulates adjustments to Frequency Response Function (FRF) data through a notch function, enabling "what-if" scenario analyses.
• Robust Design Analysis: Evaluates the robustness of Finite Element Analysis (FEA) models against variations in solution parameters, ensuring reliability in design.
• User-Friendly Interface: Features a Process Flow Graphical User Interface (GUI) and Control File GUI for batch processing, enhancing user experience and efficiency.
• Integration with FEA Software: Compatible with major FEA environments such as Nastran, Abaqus, Optistruct, and Ansys, allowing seamless integration into existing workflows.
