Embodiment Construction

[0022] At a high level, the present disclosure is directed to computer aided engineering programs and systems for evaluating the structural performance of refrigerant lines of A / C systems. The system simulates the forces exerted on components of the A / C system by refrigerant charging equipment typically used during vehicle assembly. The systems and procedures take this force into account, along with A / C line geometry and material properties, and determine the maximum deflection and maximum stress exerted on the components of the A / C system by the refrigerant charging device. With the procedures and systems described, A / C piping geometries and materials can be selected, tested and optimized prior to prototype fabrication and physical testing.

[0023] Referring now to a schematic description of a representative vehicle A / C refrigerant system 100 figure 1 . As is well known, the system 100 includes at least a plurality of A / C lines 102 and a filler port 104 through which refri...

Abstract

A system for virtual testing of a vehicle air conditioning system includes a processor-based subsystem executing instructions including at least a rendering engine configured to render a three-dimensional A / C line assembly geometry representation and an finite element analysis engine configured to simulate an A / C refrigerant charging process. The finite element analysis engine simulates a refrigerant charging process including one or both of an application of a vertical load on the simulated A / C line assembly and at least one horizontal load applied on the simulated fill port. The finite element analysis engine calculates one or both of a fully applied vertical load and / or horizontal load fill port deflection and a residual simulated A / C line assembly deflection. The rendering engine is configured to render a representation of a fill port strain contour at one or both of during and after the simulated application of the horizontal and vertical loads.

Description

technical field [0001] The present disclosure generally relates to vehicle air conditioning (A / C) lines. More specifically, the present disclosure relates to procedures for the analysis of the structural performance of an A / C line assembly, such as during a refrigerant charging process performed during vehicle assembly. Background technique [0002] During the assembly process of the vehicle, automotive refrigerant is supplied to the vehicle's air conditioning (A / C) system through a filler port which is in turn fluidly connected to the piping containing the A / C line assembly. During the process of refrigerant charging, the filler port and A / C pipes are subjected to various stresses. However, there is currently no standardized procedure for analyzing A / C line integrity. [0003] To meet this need in the art, the present disclosure relates at a high level to procedures and systems for the analysis of the structural integrity of A / C piping. Advantageously, the procedure is...
