Detailed thread modeling · Structured meshing · Joint simulation
From thread profile and fit to contact, preload and local response.
Investigate how small geometry changes affect the design.
For the design and analysis of threaded joints.
Define profiles and combined thread configurations explicitly. Design the internal and external profiles together and check clearance and constraints before developing a new thread concept.
Start with a metric profile and examine internal and external thread dimensions, tolerances and fit. Keep design parameters and geometric constraints in the same project.
Thread angle 60° · Pitch 3.5 mm
Go from standard fits to custom profiles, combined threads and special fasteners.
The interactive profiles illustrate fit geometry. The clearance slider is a visual aid only.
Model the bolt, nut and clamped members together. Keep the engineering context from part definition and assembly through meshing and analysis setup.
Actual case geometry, with the thread root, flank and axial segments represented as inspectable features.
Choose an equivalent or detailed representation. Define the root radius, threaded length, plain shank and support geometry to suit the analysis.
Align, face-align, offset, and phase with the nut to allow inspection, adjustment, and further editing of the assembly position. Sectioning and disassembly help to see the internal structure.
Precise threads are connected to structured hexahedral meshes. Thread root details, region transitions, and quality checks organize the discrete, allowing the mesh to carry engineering meaning.
Materials, friction contact, preload, boundary, and external load together compose the analysis. Observe the response along the analysis step, linking local stress with the overall connection state.
M30 × 3.5, four-part connection. Maintain consistency in material, load, contact, and mesh strategy, and compare M and MJ thread profiles. Let changes correspond to causes, and let conclusions return to conditions.
Section the structure, observe how stress passes through each thread
From equivalent stress to plastic strain, let local hotspots be traceable.

The linear-elastic case uses peak integration-point S33 at the roots of six fully engaged external threads. Normalize using the bolt force computed for that step and the actual root section area of each profile. Step two applies an external axial load after FIX_LENGTH. Local elastic peaks alone do not establish strength compliance.
In the elastoplastic case, the bolt uses a representative property class 10.9 material curve. The nut and plates remain elastic. Stress amplification after yielding is outside the definition of linear-elastic Kt. For plasticity comparisons, use thread-root p99 PEEQ and the extent of the plastic zone. Peak plastic strain remains sensitive to mesh size.
Web reads saved Abaqus case data, without real-time solving. Specific results only correspond to the conditions of this case.
Organize parts, assembly, mesh, and analysis within the same engineering. Leave the view to the structure, and let parameters, tasks, and results be expanded when needed.
Modeling and simulation share the same engineering setup.
PartAssemblyMeshAnalysisResultsConsult, review, operate. AI is connected to objects, parameters, and tasks in current engineering, helping you move from 'what to study' to 'how to proceed next.'
Organize around the selected part, mesh, analysis, and results for questions and answers, reducing repeated descriptions
Before operation, clearly see the impact, proceed within the confirmed task range, and retain verifiable operation records.
From scheme preparation, task execution to result comparison, let repetitive work form a continuous process.
AI is an optional collaborative capability, and the model service is connected according to user configuration.
From a goal, expand verifiable engineering steps.
Confirm the thread profiles, materials, and load baseline of the two groups.
Establish comparison task, retain original plan.
Check case records and read the corresponding analysis step.
Associate thread root response, convergence, and interpretation conditions.
Create a comparison task; read the saved case. The original plan is retained.
Pre-set interactive demonstration; no model connection service, no solver execution.
From a model's response, to a group of solution understanding. TD Forge's product direction is to connect geometric design, analysis preparation, and engineering judgment continuously.
Around thread profile, thread root, engagement length, and preload scheme, conduct parameter studies, sensitivity analysis, and optimization. Retain the baseline, compare the benefits, and also the costs.
More rich modeling and mixed mesh, more automatic convergence study, loading organization, and task scheduling, leaving energy for truly needed judgment issues.
Extend to per-tooth load, contact, and plastic study, professional post-processing, and verifiable reports. Gradually connect design verification, knowledge data, and test results.
Communicate with the product team about structural, thread profile design, or connection analysis requirements.
