Summary of 3DEXPERIENCE Physics Results Explorer: Point Fastener Resultant Sensor Guide

This guide focuses on the precise extraction and analysis of resultant forces and moments occurring at connection points such as Spot Welds, Bolts, and Rivets using the Point Fastener Resultant Sensor.

1. Overview of the Resultant Sensor

The Resultant Sensor is a tool used to quantify load data at specific connection points to evaluate the structural integrity of point fasteners.

• Target Components: All point-based connection elements within a simulation model, including Spot Welds, Bolts, and Rivets.
• Core Function: It extracts Force and Moment components sustained by the connection, allowing for direct comparison against design requirements (e.g., allowable load limits).

2. Sensor Creation and Key Configuration

Sensors are created via the Sensors section of the Action Bar. The following parameters must be defined:

• Support & Elements: Select the specific set (Support) to be measured and the corresponding elements to be included in the calculation.
• Step & Frame: Specify the exact simulation step and frame (time increment) from which to extract the data.
• Axis System: Set the reference coordinate system to calculate load components (Fx, Fy, Fz, etc.). Users can choose between the Global coordinate system or a User-defined system.
• Show Glyph: Determine whether to visualize the force and moment directions as arrows (glyphs) directly on the 3D model.

3. Data Verification and Reporting

Extracted data can be reviewed and managed through various interfaces:

• Sensor Tree: All created sensors are managed within the tree structure, enabling users to check or modify values at any time.
• Result Table: Load data from multiple fasteners can be compared at a glance in a tabular format, allowing for the rapid identification of the most vulnerable connection points.
• Data Export: If necessary, data can be exported to external formats (e.g., Excel) for additional strength calculations or official report generation.

4. Key Advantages and Value

• Automatic Updates: Even if the model geometry or mesh changes and a re-analysis is performed, the load results are automatically updated via the predefined sensors.
• Intuitive Visualization: The Glyph feature allows engineers to immediately identify load paths and concentration areas, accelerating the decision-making process.
• Design Optimization: By quantitatively verifying the loads on each fastener, engineers can optimize the design by reducing the number of fasteners or adjusting their positions.
