Adopting an optimized shielding design, the system eliminates electromagnetic leakage and features ultra-low self-emission, effectively avoiding background signal interference and guaranteeing authentic, repeatable test results. It supports full-condition dynamic simulation for both 2WD and 4WD vehicles, covering new energy vehicles, passenger cars and light commercial vehicles. The stepless 360° continuous rotation realizes automatic full-perimeter EMC scanning without manual vehicle repositioning, significantly boosting test efficiency and lowering labor intervention.
With a compact and integrated layout, the product simplifies installation and maintenance, saves anechoic chamber space, and reduces overall laboratory construction and operation costs. Reserved expansion interfaces for driving robots and ADAS test modules enable compatibility with EMC testing for intelligent and autonomous vehicles. Delivering standardized, efficient and high-precision test solutions, it serves global automotive OEMs, third-party certification labs and research institutions.

Q 1： What testing scenarios is this integrated turntable chassis dynamometer mainly applied to?
A1: It is specially developed for vehicle EMC electromagnetic compatibility test. It can realize the synchronous combination of vehicle road condition simulation and electromagnetic radiation emission test, and support EMC full-index tests of passenger cars, new energy vehicles and commercial vehicles in an anechoic chamber.
Q 2： What core advantages does the integrated turntable design bring to EMC testing?
A2: The integrated turntable can realize 360° accurate rotation of the whole vehicle under dynamic loading, which fully meets the requirement of multi-angle radiation emission measurement in EMC standards. It avoids repeated vehicle parking and moving, greatly shortens the test cycle, and ensures the consistency of test environment.
Q 3：Can this dynamometer simulate real road driving conditions during EMC testing?
A3: Yes. It can stably simulate working conditions such as vehicle acceleration, deceleration, constant speed, climbing and frequent start-stop. It can apply accurate torque and speed load to the wheels while conducting electromagnetic testing, reproducing the real electrical working state of new energy vehicle powertrain.
Q 4： Do you support customized modification for different vehicle types and anechoic chamber sizes? What about after-sales service?
A4: We provide full non-standard customization services. We can adjust turntable bearing capacity, wheelbase range, dynamometer power and electromagnetic shielding structure according to customers’ vehicle models and anechoic chamber parameters. We provide on-site installation, calibration, operator training, long-term warranty and lifelong remote technical support.
