Product Description

The HOWANN Hydraulic Automotive Chassis Road Simulator accurately replicates real-world road profiles—including potholes and cobblestones—inside the lab for non-destructive dynamic excitation testing. Designed with high-response servo-hydraulic actuators and a closed-loop digital controller, it allows engineers and technicians to rapidly isolate NVH issues, squeaks, and suspension fatigue without time-consuming field road trials.

Key Features & Benefits

4-Axis Independent Dynamic Excitation: Replicates real-world road profiles (cobblestone, potholes, highway vibration) to pinpoint structural squeaks, rattles, and suspension noise under precise laboratory conditions.
Servo-Hydraulic High-Response Actuators: Delivers high dynamic force with high-frequency frequency response, ensuring high fidelity for both Durability Testing and NVH (Noise, Vibration, and Harshness) evaluation.
Closed-Loop Feedback Control: Real-time displacement and force sensor control maintains sub-millimeter accuracy, allowing repeatable test cycles without wearing down vehicle components on actual test tracks.
Adjustable Wheelbase & Track Width: Universal wheel pad design supports passenger cars, SUVs, and light commercial vehicles with fast setup and flexible mounting interfaces.
Integrated Safety & Diagnostics: Equipped with over-travel protection, emergency hydraulic drop, and automated oil temperature monitoring for continuous multi-day fatigue testing.
