The single-axis hydraulic pulser is used for the investigation of static and dynamic characteristic curves on a wide variety of vehicle components.

Functional Description

The single-axis hydraulic pulser of the Chair of Automotive Engineering is used for the investigation of static and dynamic characteristic curves on a wide variety of vehicle components. Currently, shock absorber, engine mount and tire characteristics are determined. The measuring system receives a force response from a sinusoidal, rectangular or ramp-like path excitation.

Fields of Research

• Determination of shock absorber characteristics
• Investigation of the influence of temperature on engine bearing characteristic curves
• Influence of preconditioning cycles on hydromount characteristic curves
• Natural frequency testing of tyres
• Investigation of the temperature influence of rubber samples from tyres or bearings

 

Planned Extension

• Torsion and cardanic testing device for hydromounts
• Extension to a hydraulic two-axis hydraulic pulser for applying a transverse force in tension and compression direction
