Current capabilities and capabilities to be supplemented
Need to add new core
Need to add core computing
Light point extraction can only be used as an observation front-end, and core capabilities such as three-dimensional reconstruction, closed-loop control, wavefront or physical quantity inversion need to be developed and verified separately.
Gaps in this scenario:New structural stiffness, boundary conditions, force/strain model and cross-axis compensation need to be added; displacement is not directly equal to force. Diaphragm nonlinearity and temperature effects require a model. Forces, moments and strains must be mechanically modeled and independently calibrated
Route-level gaps:New structural stiffness, boundary conditions, force/strain model and cross-axis compensation need to be added; displacement is not directly equal to force
"New cores required" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.
Verification methods and acceptance prerequisites
Use standard weights, force sensors or strain gauges to conduct cyclic loading blind tests to verify hysteresis and creep. Weights, standard force sensors and multiple loading return comparisons
