LCG Automotive models of chassis dynamometer
Chassis dynamometer, also known as drum tester, is a kind of laboratory test equipment. It is used to simulate the resistance of the automobile in the actual driving process, determine the performance of the automobile, detect the technical state of the automobile, and diagnose the automobile fault. Chassis dynamometer can be used not only in automobile scientific test, but also in maintenance and production.
Chassis dynamometer adopts steel plate bending welding body, good strength, beautiful appearance. Installation and commissioning are very convenient, especially in flooded areas where temporary lifting is required. Single beam air bag lifting, lifting synchronization is good, no maintenance, no oil. It is mainly used for detecting engine power without external load dynamometer and detecting maximum output power and maximum speed of automobile by chassis dynamometer. ... The maximum driving power of the chassis is measured by the chassis dynamometer to evaluate the technical status of the vehicle. It is composed of a roller, a power absorption unit and an inertial simulator, which is used to simulate the road resistance of vehicles.
Structural function
The inertial flywheel simulates the revolving body of a car
Inertia moment and motor inertia
The energy-absorbing loading device simulates the air resistance, rolling resistance and climbing resistance of the non-driving wheel in the running process of an automobile.
Use a roller to simulate the road surface, that is, the surface of the roller to replace the road surface. The surface of the drum rotates relative to the car.
There is a lifting device between the main drum and the secondary drum to facilitate the vehicle to enter and exit the chassis dynamometer.
Data acquisition and control system, data acquisition and processing, data acquisition and processing is mainly composed of data acquisition card, speed sensor, tension pressure sensor, photoelectric switch and the corresponding data processing circuit.
Control system
The control system consists of control module and executive component. The control system is to convert the control signal given by the user into analog signal in the form of digital signal to control the behavior of the actuator, so that the parameters of the controlled object can meet the requirements of the user.
There are usually restraint devices for preventing the vehicle from swinging and longitudinal movement, cooling devices for the engine and tires, and display devices.
The cooling fan simulates the wind when the car is running and keeps the engine in a normal hot state.
Automobile anti - wheel swing device. In the device, two anti-roll rollers find the position of the wheel to prevent the wheel from swinging at high speed.
Features
Automobile chassis dynamometer, through a balanced vehicle dynamics theory, to test the vehicle chassis output
power, power to evaluate the performance of vehicles: On the other hand through the air-cooled eddy current dynamometer smoke test car load of resistance to simulate vehicle roadworthiness actual state of implementation working condition and working condition emission test fuel consumption test.
Zibo lingxin owns the independent intellectual property rights of the product, and has the type certification issued by the provincial quality and technical supervision bureau.
Automobile chassis dynamometer is indispensable testing equipment, vehicle maintenance and repair work the test circuit design adopts advanced integrated circuit (e.g., precision timing circuit) and the new element (high power switch integrated circuit, etc.), stable performance, strong anti-interference, instruments and small power consumption, beautiful generous, the test accuracy, clear reading, applicable to vehicle electrical test of gasoline and diesel engine.
