摘要： A method of evaluating a product for use on a body used to develop a preferred product configuration using a computer-based virtual product development and testing system. A virtual wearer sub-model is created of the body and a virtual product sub-model is created of a product for use on the body. An environment sub-model is generated so that environmental factors affecting the product or the body are also used in designing or evaluating the product. Instructions defining how the wearer sub-model, the product sub-model and the environment sub-model interact are introduced in an interaction model. The sub-models and the interaction defined by the interaction model are then combined to create a virtual use model simulating the use of the virtual product sub-model by the virtual wearer sub-model. The use model determines the forces, deformations and stresses caused by movement and interaction between the virtual wearer sub-model and the virtual product sub-model using numerical method analysis. The results of the use model are analyzed to evaluate the performance of product features embodied in the virtual product sub-model such as when positioned on a virtual wearer and exposed to typical movements or forces. The analysis evaluates the performance of at least one product feature of the product and/or wearer body.

摘要： A method of designing a product for use on a body used to develop a preferred product configuration using a computer-based virtual product development and testing system. A virtual wearer sub-model is created of the body and a virtual product sub-model is created of a product for use on the body. An environment sub-model is generated so that environmental factors affecting the product or the body are also used in designing or evaluating the product. Instructions defining how the wearer sub-model, the product sub-model and the environment sub-model interact are introduced in an interaction model. The sub-models and the interaction defined by the interaction model are then combined to create a virtual use model simulating the use of the virtual product sub-model by the virtual wearer sub-model. The use model determines the forces, deformations and stresses caused by movement and interaction between the virtual wearer sub-model and the virtual product sub-model using numerical method analysis. The results of the use model are analyzed to evaluate the performance of product features embodied in the virtual product sub-model such as when positioned on a virtual wearer and exposed to typical movements or forces. The analysis evaluates the performance of at least one product feature of the product and/or wearer body. The product sub-model is then modified in response to the determined performance of the product feature and the steps of interacting the models and combining the models are reperformed in the use model to design the product.
