Study bench for structures

Contents and technical specifications of the basic configuration (EW10):

Electric cylinder (2500N)with incremental encoder for displacement measurement

Digital comparator for displacement measurement

3 force and torque sensors (with associated device)

Mounting bases

Tension clamping jaws

Simple (semi-cylindrical) fulcrums, pivots andfittings

Ceiling-mount with distribution plates

Controller and datalogger(force and displacement) with software

Set for simple tests (support beams, Portal frames, Truss).Safety enclosure for testing (EW09 version)

Training activities:

Static studies of beam bending (simple with two fulcrums, simple with fittings at one end, simple with 4 points of which two are fulcrums)

Staticstudies of traction

Static studies of compression

Static studies of support beams (two forces and momentum applied to a solid…)

Static studies of portal frames and truss(vertical force applied to a solid)

Studying frames made of wire mesh, e.g. rail bridge

Studying arches, e.g. rail bridge

Studying the structure of buildings, e.g. metal building with flat roof

Studying the structure of buildings, e.g.. metal building with slanted roof

Studying an mountain bike crankset with pedals

Distortion of a mountain bike rod, subjected to 3 concurrent forces

Key points:

Test control andmeasurements(force, displacement and constraint) on PC interface

Huge test enclosure (LxBxH=1500x700x1000mm) enabling tests on 3D structures

Possibility of combining forces applied by two cylinders

Tensile, compression, bending, torque and torsion measurements

Many available mechanical parts and frames (standard or optional)

Possibility of performing tests safely on any structure
