Description
  • Posuvy a deformace pláště pneumatické pružiny, který je zhotoven z kompozitu s pryžovou matricí vyztuženou kordy, jsou určeny pomocí metody stereokorelace. Jsou stanoveny 3-D souřadnice bodů v centrální části pláště při postupném zatěžování vnitřním přetakem triangulací ze souřadnic serie digitálních snímků dvou kamer. Deformace pláště jsou vypočteny pomocí nelineárních nejmenších čtverců. Metodu lze použít k určení 3-D deformací různých objektů. (cs)
  • In this paper, the three-dimensional (3D) displacements and deformations of inflated cylindrical shell part of air-spring made of composite material with rubber matrix reinforced by textile cords are measured by the application of the stereo-correlationechnique. The 3D coordinate of points in the central part of air-spring shell are obtained at different stages of loading using digital image correlation. By the use of the nonlinear optimization technique, the equation of cylindrical surface of air-sprig shell is solved to obtain a set of parameters, the direction cosine of the centerline of the cylinder, the point of intersection of the centerline of the cylinder with the XZ-plane, and the radius of the cylinder. The computed radius of the cylinder iscompared to the measured value to evaluate the measurement error. Results indicate that the stereocorrelation technique may accurately measure the curved surface in variouscurvatures.
