Car testing system for anechoic EMC chamber
Characteristics
- Widely adjustable wheelbase (1650-3200 mm)
- Low weight (2000 kg)
- Easy to move with self-supporting wheels
- Only pneumatic actuators and braking system (similar to a dynamometer)
- Cooling fan with pneumatic motor
- All rollers are mechanically connected
Customer Needs
The client, a laboratory for a major certification body, requires a mobile test bench capable of supporting cars and a three-wheeler during EMC testing, applying 6 kW of power (at 50 km/h) to the rollers, simulating a straight path on all four (or three) wheels. After the test, the device must be easily movable outside the anechoic chamber. The maximum weight of the cars being tested is 2,850 kg. The maximum weight of the device must be 2,000 kg. The test bench must be shaped so that sports cars can easily mount it without touching the structure. Only optical sensors for speed measurement are permitted.
Solution
Through diligent research into solutions and structural simulations, we have developed a multifunctional test bench capable of satisfying all the needs listed above.
