摘要： A method for filling a compartment cavity, such as a refrigerative unit cavity, with a foam produced by an expansion and solidification of a foaming mixture of predetermined chemicals. A known amount of the foaming mixture is created in a test chamber cavity and preselected parameters (such as free surface height and pressure) are measured to obtain the average density and apparent viscosity of the foam as a function of time. A computer program uses the average density and apparent viscosity data to simulate the foaming process for various starting quantifies and starting locations of the foaming mixture. A preferred quantity and location are chosen from a particular computer run which satisfies predetermined fill criteria. The preferred quantity of the foaming mixture is then created at the preferred location in the compartment cavity.

摘要： A spray coating simulation for a robotic spray gun assembly imports a discretized model of an object geometry. Next, the simulator imports a numerically characterized spray pattern file and a robot motion file having a plurality of motion positions, dwell times and orientations defining a motion path of the spray gun. The individual motion positions within the motion file are read and a determination is made as to which portions of the object geometry are visible at each motion position. Next, a coating thickness at each visible portion of the object geometry is computed, based on the specified spray pattern data, the dwell time and the orientation of the robot motion path, for each motion position. Finally, the total coating thickness over the object geometry is calculated.

摘要： A method for enabling design of a profile extrusion capping die includes, obtaining a size and configuration of a land formable by the capping die, obtaining material properties of a capping resin, obtaining operating conditions for processing the capping resin, and determining, from the size and configuration of the land, the material properties, the operating conditions, at least one of a velocity distribution and a pressure distribution of the capping resin adjacent to an outlet of the land. Desirably, the method also includes obtaining a size and configuration of a runner formable by the profile extrusion capping die, and determining at least one of the velocity distribution and the pressure distribution of the capping resin in the land and the runner. Advantageously, the method is implemented on a system or computer using a finite element mesh of the land and the runner and graphically displaying the velocity distribution and the pressure distribution. The system allows a designer to design a profile extrusion capping die electronically by revising the size and configuration of the land, runner, and/or inlet gate, to obtain a uniform velocity of the capping resin along the land outlet thus resulting in a capping having a uniform thickness.
