Abstract: In order to apply virtual reality technique onto hydraulic universal testing machine for creating a virtual experiment scene and realizing virtual testing, CAXA, VRML (virtual reality modeling language) and Javascript are applied. System's three dimensional modeling is built by CAXA and transformed to wrl form document. The virtual reality model of hydraulic universal testing machine is created by using Inline node. The essential animation is realized by using TimeSensor, Interpolator and ROUTE sentences. Sample deformation animation and sample mechanics performance simulation are realized by using Javascript technique. Interactive operation in real time is made by using TouchSensor. Specimen information extraction is realized by using anchor node.
