Thermal deflection analysis

摘要

An optimization wizard substantially automates the task of calculating thermal deflection analysis of a part. The optimization wizard requests a user to provide a mesh model representing the part and provide part definitions, such as the part's stiffness, expansion coefficient, etc. In addition, the wizard requests the user to provide boundary conditions by modifying normality of any elements in the mesh model and by fixing conditions of one or more nodes in all direction or in a one sliding direction. An initial and a final temperature may also be provided by the user. The optimization wizard receives the user inputs and generates an executable file describing the relationships and effects each input has on the part's deflection under the provided thermal conditions. The executable file is provided to a solver to determine the part's thermal deflection under the provided conditions.

1. A computer based method for calculating thermal deflection of a part at a load temperature, the method comprising:
importing a mesh model of the part, the mesh model representing the part in a three dimensional space; requesting a user to provide properties of the part, the properties affecting deflection of the part; receiving a boundary condition selection from the user, the boundary condition selection comprising a boundary condition and one or more nodes of the mesh model, the one or more nodes located along an edge of a portion of the part; identifying additional nodes along the edge of the portion of the part based on the selected one or more nodes and the boundary condition; applying the boundary condition to the selected one or more nodes and to the identified additional nodes; requesting the user to provide an initial temperature of the part and a load temperature of the part for analysis; receiving the requested properties of the part, the initial temperature, and the load temperature; and generating an executable file based on the received properties of the part, the boundary condition, the initial temperature, and the load temperature, the file executable by an application to calculate localized deflection in the part.
