The deformation of degree, the stress feelings of each segment of windscreen are measured using each fixture three-dimensional force sensor (6) along contoured profile
Condition；
(5) using the fixing end windscreen and the dynamic outline of tache motorice windscreen contact area of video camera captured in real-time, using binocular
Vision measurement principle extrapolates the deflection of each section of windscreen, you can calculate the rigidity and damping characteristic of each section of windscreen.
