STAND FOR FATIQUE TESTS OF THE TUBE SAMPLES AND CONSTRUCTION ELEMENTS, ESPECIALLY OF THE BICYCLE FARKS

摘要

1. A station for fatigue tests of pipe samples and structure components, in particular for bicycle forks, fitted with a D.C. motor, thyristor controller for the rotational speed, an inertial vibrator and a frame, characterised in that a sample or a tested component is one-side arm-mounted in the frame (12) and the free end of the sample is joined with an inertial vibrator (4) by a tensometric dynamometer (5), whereas that tensometric dynamometer is connected by a control and metering circuit with the electric motor (3), which drives the mechanical vibrator.IMAGE
