Welding Simulation

Goldak - VrSuite


Más de 40 años de trabajo científico se combinan en una poderosa herramienta de simulación, que es especialmente desarrollado para soldadura, tratamiento térmico y fundición de Goldak Technologies Inc. in Ottawa, Canada

"The primary aim of the work is to transfer this technology from the research specialists who are devoleloping it to the engineers who must apply it in the design and production of welded structures" [Goldak 1985].
"El objetivo principal del trabajo es transferir esta tecnología de los investigadores que la desarrollan a los ingenieros que deben utilizarla en el diseño y ejecución de piezas soldadas" [Goldak 1985].

Esta visión de John Goldak conduce a un software respaldado por el diseñador que cumple con los principales problemas y requisitos para el código numérico de una herramienta de simulación de fabricación:
  • extremadamente potente - resultados de simulación rápida
  • muy robusto - cada simulación conduce a resultados
  • alta precisión - alta calidad de resultado
todo esto en combinación con una interfaz de usuario fácil de usar que automatiza tantos pasos como sea posible.
Goldak - VrSuite contiene los siguientes módulos:
  • VrHeatTreat para el análisis del tratamiento térmico, incluida la cementación
  • VrWeld para el análisis de soldadura incluyendo el análisis proceso y estructural
  • VrFrac para la mecánica de fracturas para predecir riesgos de fatiga o grietas
  • VrOptimizer para reducir la deformación y las tensiones residuales de soldadura
Goldak Vr Suite tiene en cuenta todos los fenómenos físicos necesarios para el cálculo. El complejo sistema se resuelve mediante diferentes solucionadores acoplados y paralelos en un cálculo 3D totalmente transitorio:
  • Análisis térmico
  • Generación de baño de fusión y cálculo de la entrada de calor/li>
  • Microestructura, dureza, transformaciones de fase, solidificación
  • Análisis mecánico - tensiones, alargamientos, deformación
  • Efectos de difusión - Charring
Ampliado por una simulación a microescala para el análisis de microestructuras y fatiga, así como para el análisis de optimización.

El código VrSuite utiliza tecnología GPU.

Los resultados se pueden utilizar como estado de inicio para el siguiente paso de simulación en todos los módulos. Además, se pueden importar los resultados de cálculo de diferentes soluciones de software externo. También es posible exportar los resultados de VrSuite para varios solucionadores. Esto permite en última instancia la simulación de la cadenade proceso, que es esencial para las simulaciones de fabricación.
