The aim of this article is to describe the design of GRP bogie frame and the performance of testing procedures for this frame, made in Dynamic testing laboratory in SKODA VYZKUM s.r.o. Tests of bogie longitudinal beam set-up are introduced, including static, sweep, harmonic oscillation and drop tests. Initial tests at shaker test rig of GRP25-1 bogie on Smms wagon are also described. The test evaluation includes the damping coefficients, natural frequency and beam strains and deflection during the tetsts of the structure.
