HyperXtrude for Metal Extrusion


hmtoggle_arrow1Automatic Ram Speed Correction Based on Press Tonnage

The solver can automatically adjust the ram speed based on the limits imposed by the press data. This will help to determine the maximum ram speed possible on the press for the given process data.

 

hmtoggle_arrow1Improvements to Modeling Choked Bearing

An improved algorithm is implemented to compute friction at choked bearing regions based on test data and the computed results correlate well with extrusion field data.

 

hmtoggle_arrow1Dead Cycle Time

The solver is enhanced to include dead cycle time in a full cycle transient analysis. This helps in computing more accurate temperature distribution before the next cycle begins.

 

hmtoggle_arrow1Thermal Analysis of Tool Heating Systems

The solver has a new feature to do a thermal analysis of the tool heating systems and control tool assembly temperature. HyperXtrude can now perform a transient analysis to monitor temperature at the pre-defined thermocouple locations and control the heating elements based on the feedback from thermocouples. Since temperature plays a critical role in extrusion, this analysis is useful in understanding and controlling the thermal systems that heat components such as, container, liner, and die assembly.

 

hmtoggle_arrow1IGES File Export of Optimized Bearing Curves

When doing bearing optimization, HyperXtrude will now write CAD files in IGES format for the optimized/corrected bearing curves. This will enable easy import of these optimized bearing curves into HyperMesh or HyperXtrude 2015.

 

hmtoggle_arrow1Tool Deflection Analysis Using OptiStruct

The solver is enhanced to perform coupled simulation using OptiStruct for tool stress analysis. In this approach, after performing extrusion analysis on the workpiece, HyperXtrude will automatically invoke OptiStruct with the computed loads to perform tool stress analysis. Extrusion analysis is then continued by taking computed tool displacements into consideration.

 

hmtoggle_arrow1Resolved Issues
Error in writing displacements in H3D file for bearing optimization runs has been resolved.
Improvements to bearing friction module has been made to increase the accuracy of the solver.
Resolved errors in gap contact load computations in coupled analysis using HyperXtrude.
Resolved limitations in particle traces module. This data is used with a standalone code for visualizing particle traces with history in HyperView.
Resolved issues when skin tracking is enabled in models that use lookup table for material data.
Enabled function/table specification of heat transfer on free surface BCs.
Resolved many minor issues related to transient analysis as part of dead cycle time implementation.

 

 

HyperXtrude for Polymer Extrusion


hmtoggle_arrow1Improvements to Calibration Analysis

Major enhancements are made to calibration analysis and these include improvements to computational time and extracting additional useful results specific to cooling of the extruded profile. New results include solidified layers, solidification time, degree of cooling, and cooling time.

 

hmtoggle_arrow1Resolved Issues
Issues related to viscosity data in lookup table format (as function of strain rate and temperature) have been resolved.

 

 

HyperXtrude for Resin Transfer Molding


hmtoggle_arrow1Resolved Issues
Issues related to VARTM resin infusion has been fixed.
Improved robustness of filling even for complex models with drastically varying data
