Measurement of Mechanical Stress

Measurement of Wheel Force for Durability Analysis at Daimler Truck

At Daimler Truck in Wörth (Germany), new trucks are being developed to production readiness. In road tests, the forces and torques acting on the rotating wheel are precisely recorded using the Kistler KiRoad Performance system. At the same time, CSM measurement technology is used to measure up to 200 analog channels in order to be able to make statements about the mechanical loads in the components. With the KiRoad Performance Gateway, which was developed specifically for this project, the measurement data from the various systems can be synchronously acquired and evaluated.

Measurements of the Mechanical Load of a Solar-powered Passenger Car Test Vehicle

Along with the shift from combustion engine drives to electromobility, the question arises of where the electricity will come from to run e-motors in vehicles in the future. One idea: solar panels integrated into the vehicle to charge the battery. For this purpose, a fleet of solar-powered test vehicles has been developed as part of Sono Motors' Sion program. CSM accompanied the integration of the necessary measurement technology for acquiring the mechanical loads and the electrical power of the powertrain for one of the vehicles.

Durability Measurement on Tie Rod and Axle Control Arms

Optimization of electric and hybrid vehicles often focuses on components in the electric powertrain. However, to increase range and efficiency, a perfect balance of weight and stability is required for numerous components. This compromise is particularly challenging for heavily stressed components such as the chassis. This application example shows how the measurements for durability analyses are carried out on tie rods and axle control arms.

Experimental Stress Analysis on Crane Booms

Mechanical stresses and their direction must be determined for the structural design of many components with experimental stress analyses. The exact knowledge of the structural load-bearing capacity is particularly relevant for the development of components on construction machines that are later subjected to heavy loads. This application report shows how CSM measurement modules accurately measure stress at numerous locations during repeatable experimental stress analysis on telescopic crane booms.
