Comprehensive Roller Test Stand - Soundproof Room
The soundproof room is easy to disassemble and assemble, and the inner wall is filled with sound-absorbing materials. In addition to supporting its own weight, the supporting structure of the soundproof room can also withstand the weight of other additional objects on the soundproof room, mainly including extraction and exhaust fans, maintenance hoists, steel structures, traffic mirrors, air pipes, etc.The soundproof room has an independent indoor exhaust gas exhaust device, and an independent fan can be independently controlled;The soundproof room is provided with a safety device, and three pairs of photoelectric switches are respectively installed on the front and back door frames. When the automatic door is closed, the moving door stops and opens when the photoelectric is blocked;To open the front door of the soundproof room, two conditions must be met at the same time: the comprehensive drum table has been completed and the vehicle has touched the photoelectric switch, and the automatic door cannot be opened automatically;Warning lights are set on the left side of the front and back doors of the soundproof room. Green: the automatic door has been fully opened (vehicles and people can safely enter and exit) Red: the automatic door is being opened or closed (vehicles and people are forbidden to enter and exit the soundproof room); Yellow light: the automatic door has been closed (multi-function equipment test); The inside and outside of the soundproof room are equipped with emergency stop buttons and manual switch automatic door buttons;
Description
The structure of the test bench is mainly composed of a bracket, a large mobile base, a moving guide rail, a basic frame, a motor, a reduction wheel, a hub assembly, a pneumatic lifting device, a speed sensor, a displacement sensor, a frequency converter and other components.The drum test bench uses the electric inertia to simulate the kinetic energy of the vehicle on the road, and can withstand the load of the vehicle at the maximum acceleration and deceleration. Rotary drum warp good dynamic balance. It has the following functions:Dynamic driving brake force test: the car drives the drum. When the speed of the car reaches 80 km/h (the speed can be set by the user), brake until the car stops, and measure the dynamic driving braking force during the deceleration process.Astern test test (open or close as required).Acceleration performance (on or off as required)Automatic transmission testing and diagnostics, communication with the automotive ECU, according to test specifications (open or close as required).A safety drum protection device is installed at the rear of the rear drum group to prevent the vehicle from running out of the test stand during the test. In order to facilitate vehicle access to the test bench, a pneumatic lift is installed in the middle of each pair of rollers.
