Motor vehicle safety performance testing line-flat type
The flat-plate brake test bench is a device for dynamic testing of vehicle braking performance at low speed. Its detection principle is based on Newton's second theorem "the resultant external force of the motion of an object is equal to the mass multiplied by the acceleration of the object". Theoretically speaking, the braking force is only determined by the braking deceleration and has no necessary connection with the initial braking speed.

The working principle of the flat-plate brake test bench:
The flat-plate brake test bench is a device for dynamic testing of vehicle braking performance at low speed. Its detection principle is based on Newton's second theorem "the resultant external force of the motion of an object is equal to the mass multiplied by the acceleration of the object". Theoretically speaking, the braking force is only determined by the braking deceleration and has no necessary connection with the initial braking speed.
During the inspection, the car drives on the measuring plate at a speed of 5km/h to 10km/h, and sets the transmission in neutral. The brake sensor connected to the measuring plate measures the neutral sliding resistance of the wheel of the tested axle, and the load cell simultaneously measures the wheel load of the axle. When the driver slams on the brakes, the car acts on the inertial force, and the wheel adds a force equal to and opposite to the braking force on the measuring plate, so that the measuring plate is displaced in the longitudinal direction. The braking force of each wheel, dynamic wheel weight and various parameter values of suspension performance can be measured.
The modular design of the front and back panels can quickly and flexibly combine flat panels with different test requirements according to the actual needs of users. The brake plate surface of the flat platform adopts a special bonding composite material layer, which effectively improves the adhesion coefficient of the plate surface and reduces the degree of braking force drop of automobile tires in a wet state. The braking force test ability is high, and it can realistically simulate the braking situation of the motor vehicle road surface. The platform is equipped with a special braking force calibration tool to ensure accurate and quick completion of the braking force calibration.
Hardware list of flat safety performance testing line:
NO. | Name | Model | Remarks |
01 | Four-plate wheel heavy brake inspection bench | XKPB-4-3T | It is a vehicle testing equipment that can dynamically measure the braking force, axle (wheel) weight, and item testing of the vehicle after braking once. |
