Product Details

 

电力底盘测功机

This power chassis dynamometer is suitable for front, rear and four-wheel drive vehicles.  Temperature range -20 ° C - +60 ° C.  The two-wheel drive drum system is used to test vehicles in various drive modes. It can be operated in the following ways: road simulation, fixed speed control, fixed torque control, fixed acceleration control, etc.  Road resistance and inertia endurance tests for endurance testing and R&D testing.


Also equipped with fuel economy test equipment to test fuel consumption

Equipped with emission test equipment can also be used for vehicle emission test

A power analyzer can be used to test different electrical parameters of a hybrid or electric motor of a new energy vehicle.


The vehicle under test is fixed on the upper drum surface of the drum by a suitable fixing device. The power chassis dynamometer system consists of two drums, and the two drums are connected by a motor to form a shaft. Measuring, processing and recording traction and speed values. Based on these actual measurements, the power conditioning cabinet applies precise load resistance to the vehicle, allowing the system to provide the required road load by means of high-precision electric inertia simulation techniques. Need, the vehicle can work under steady state or dynamic conditions.

 

The electric chassis dynamometer accurately simulates the various types of resistance loads that the test vehicle performs on the road.  The dynamometer is installed underground, the vehicle is driven on the drum, and after the centering is fixed, the dynamometer simulates actual road conditions such as speed, torque or road load, and the vehicle can be tested under the simulated actual road environment.  Road load simulation is achieved by a dynamometer drive.

The dynamometer computer control system is used to accurately simulate road loads.  The road load is mainly input to the road load coefficient of various vehicles by operating the computer, and is determined and modified by calculation.  At the same time, the system also has a self-calibration function to verify the test status of the dynamometer.
