1Measurement precision
If real-world testing with physical prototype is performed, then measurement precision of component stress is improved, but loss of time and loss of energy increase significantly
Solution Approach 1:
The patent creates a virtual copy of the machine through a computer model that replicates the physical machine's behavior. This virtual model can be tested repeatedly without physical constraints, eliminating the need for actual prototype testing while maintaining measurement precision through accurate mathematical representations of stress distributions.
