All experiments including required accessories at a glance
Experiment setup: easy & fast
The complete experiment can be set up quickly and easily. No tools are required. Both the mounting frame itself and the accessories are connected to each other using a click system.
The video on the right demonstrates an exemplary experiment setup on the subject of forces in trusses.
Examples of selected experiments
Trusses are bar structures in which the bars are only subject to compressive or tensile stress, but not bending.
- measurement of the bar
- comparison of forces in statically determinate and statically indeterminate trusses
- comparison of measurement results with mathematical solution methods: method of joints, Ritter’s method of sections, FEM
MEC - Forces on a suspension bridge
Suspension bridges consist of sagging suspension cables to which a walkway or roadway is attached.
- measurement of the suspension cable forces on a oaded and unloaded suspension bridge
- measurement of the support forces as a function of the loading on the suspension bridge
- effect of a moving load
- behaviour of a suspension bridge with a rigid or flexible roadway
An arch bridge consists of an arch that either supports the bridge from below or holds the bridge from above. Arch bridges are used to span long distances.
- measurement of the arch forces on a oaded and unloaded arch bridge
- measurement of the support forces as a function of the loading on the arch bridge
- effect of a moving load
MEC - Friction on the inclined plane
Frictional forces are essential for machines. This applies to static friction in static applications and dynamic friction in dynamic applications.
- measurement of the coefficients for adhesion and friction
- determination of angular and material dependence
- measurement of distance travelled and time passed
- determination of velocity and acceleration
MEC - Cable forces and pulley blocks
Pulley blocks make it possible to lift heavy loads and are used, for example, with cranes.
- investigate 2 different pulley blocks at the same time
- 2 setup variants possible for each pulley block
- measurement of cable forces, support forces and displacement
- angular dependence of forces
- force measurement under different loads
Three-hinged arches are commonly used in bridge construction. A three-hinged arch consists of a curved beam that is mounted on two fixed bearings.
- conditions of equilibrium in statics
- measurement of internal forces on a beam, clamped on one end, and three-hinged arch
- influence of the load on the horizontal thrust in the supports
- determination of the lines of influence for the supports under a moving load
The Gerber beam is an articulated beam with several supports that is often used in bridge construction.
- experiments with different support positions and loads
- calculation of support forces
- determination of internal reactions under static load
- determine lines of influence under moving load
Smart components in detail
The use of modern measurement technology is indispensable in the structural monitoring of e.g. bridges. The competent handling of appropriate systems is essential for specialists. The MEC Line offers the opportunity to familiarise with basic digital structures.
All smart components of the MEC Line are equipped with an electronic module. The electronic module enables the direct display of measured values on a TFT display. An integrated acceleration sensor enables the automatic display alignment as well as the determination of the installation position. Different sensors allow the use for different measuring applications.
Force
- Planar beam load cells enable direct force measurement on bars, supports and loads. For this purpose, the load cell is directly adapted to the respective electronic module.
Angle
- Acceleration sensors in e.g. bars enable the precise angle measurement for the correct display of the geometry of the truss.
Path
- A linear potentiometer in the distance measurement is used, for example, to record the displacement in a truss. The articulated arm with a long reach offers a wide range of measurement options.
Position
- Gray code (reflected binary, RB) is used to determine the position of e.g. loads on a bridge. The Gray code reader integrated in the load detects the exact position using the code on the roadway.
- The GUNT topology algorithm allows the exact visualisation of the set up truss in the software. Already during setup, the bars are displayed in the correct position and angular position.
Software
The GUNT software is specifically adapted to each experiment. The experimental setups are partly transferred automatically to the software interface. The software reacts dynamically to changes. Measured values are automatically displayed in the software. In addition, an FEM calculation of the forces is carried out. The values can be optionally shown or hidden.
- measurement data acquisition and processing
- automatic identification of smart, communication-enabled components including position and orientation
- integration of FEM models
The software for SE 200.01 MEC - Forces in trusses offers the option of displaying the calculated displacement in an amplified form. For this purpose, the scaling is simply increased step by step via a button in the software. The otherwise hardly noticeable displacement thus becomes very clearly visible.
Digital media in the GUNT Science Media Center
The GUNT Science Media Center provides extensive multimedia teaching material for all experiments. Customers can access files and product information for selected products at any time and from any place. In addition to digital worksheets and the manual, access to E-Learning is also included.
