Dynamics that push components to their limits.
Reproducible pulse and load tests for the highest development requirements – electrical or hydraulic, light or heavy.
AIP's Pulser test benches enable highly dynamic load simulations for complete vehicles, modules, or components. With precise identification and iteration, real force-displacement or acceleration curves are simulated – ideal for analyzing material fatigue, vibration behavior, and NVH. Whether for electromobility, chassis technology, or heavy commercial vehicles: Pulser technology delivers reproducible, powerful, and efficient test results for research, development, and endurance testing.

Pulsing at the highest level – precise, fast, and reproducible at any time.
Electrical precision for highly dynamic passenger car applications
The AIP E-Pulser was developed specifically for passenger car and light-duty components and is based on a fully electric, highly dynamic drive system. The synchronous linear motors enable high-precision positional movements of up to approx. 0.05 mm at pulse frequencies of up to around 150 Hz. This allows realistic load cycles to be simulated, as occur in modern vehicles, chassis, or bearings.
Electric pulser systems are particularly efficient: braking energy is fed back, there is hardly any maintenance work, and the dynamics are excellently reproducible. Freely definable test sequences allow flexible mapping of different customer and standard requirements – from short pulses to cyclic endurance runs.
Highlights:
- Highly dynamic synchronous linear motors for precise pulse excitation
- Up to 370 m/s² and up to ~150 Hz (depending on the test specimen)
- Extremely energy-efficient – require up to 80% less energy compared to hydraulic solutions
- Freely programmable pulse and load profiles
Maximum power density for heavy commercial vehicles
AIP offers hydraulic pulser systems for high loads, large masses, and robust components. The servo-hydraulic technology generates extreme forces of up to ±250 kN and pulse frequencies of up to approximately 50 Hz – ideal for heavy commercial vehicles, endurance tests, and poor road profiles.
The hydraulic actuators are characterized by high power density and fast control times. This means that even heavy test specimens can be excited with realistic load profiles. The modular test bench concept can be flexibly adapted to test specimen size, force requirements, and specific customer layouts.
Highlights:
- Servo-hydraulic actuators for extreme forces up to ±250 kN
- Quickly excitable load profiles for heavy-duty components
- Modularly scalable for a wide range of customer requirements
- Ideal for commercial vehicles, military and damage testing
- High robustness for 24/7 continuous operation requirements
Vibrations accurately simulated – from components to complete vehicles
AIP's pulser test benches are designed to accurately reproduce the loads that occur in real vehicle operation – both in terms of time and amplitude. Defined pulse shapes such as square, sine, triangle, or customer-specific profiles allow detailed analysis of vibrations, damage, resonances, and NVH.
Additional modular measurement and sensor packages (acceleration, force, strain, temperature) create a fully instrumented test platform that can be scaled from component testing to complete vehicles. AIP pulser systems thus provide a central tool that can be used in development and quality assurance processes.
Highlights:
- Realistic, reproducible pulse shapes for all test specimen sizes
- Analysis of damage, resonances, and NVH behavior
- Diverse sensor packages and integrable measurement architecture
- Scalable from individual components to complete vehicles
- Ideal for research, series development, and quality assurance
