2、 Advantages
1. High precision and high stability measurement
In order to ensure the stability and accuracy of the measurement, the ModelBased Sensor uses a digital force sensor independently developed and manufactured by A&D to determine the rolling resistance measurement performance in the equipment. This sensor can minimize the impact of vibration during measurement to achieve high-precision and high stability measurements.
2. Security
This equipment is equipped with a roof shaped outer cover at the tire testing location to prevent personnel from entering during the testing process, ensuring high safety. Moreover, the outer cover is equipped with high-precision air conditioning, which can accurately control the air temperature at the tire testing position.
The air conditioner can be prepared by the customer or purchased from the air conditioner recommended by our company.
3. Fully automatic testing
In addition to international testing standards, we can also provide customers withExperimental mode ※ Customized software
■ With the function of adjusting the test schedule, the test can be adjusted according to the process
The experimental data and conditions can be saved in CSV format for the convenience of data usage and management.
4. Maintenance
Our company provides annual maintenance services in addition to daily maintenance, which can be provided by our company after signing the contract.
3、 High precision force sensor
A conventional force sensor involves setting up six sets of bridge circuits corresponding to six force components within the sensor for composite calculation, followed by one interference correction. The force sensor of A&D is equipped with bridge circuits at 8 different positions, which convert the strain output voltage signal of the bridge circuit into a digital signal, and then perform DSP simulation through DSP equipment
After processing and synthesizing signals from 8 bridges, output 6 force components. Due to the use of DSP devices in synthesis calculations, high-order term operations can be performed on sensor models to achieve high-precision synthesis calculations. Moreover, the shape of the elastic body has been changed from the previous four corner section to the I-section used for strain pressure sensors, which can design the most appropriate stress matching according to the detection direction. After the 8 signals of the strain gauges are amplified by the dynamic strain amplifier, they enter the DSP processing device and then undergo analog-to-digital conversion through the A/D input board. Based on the mutual relationship between the signals and our company'sPerform DSP calculations on the parameters and finally obtain the six component force. The calculation frequency is 1kHz (1msec). The force sensor installed on this device ensures the values of Fz (load) and Fx (rolling resistance), enabling professional measurement of rolling resistance.
4、 Highly scalable software
The standard configuration of this device can be used for testing in accordance with ISO28580 specifications. All software for this device is created using MATLAB SIimlink, which has good scalability and can be flexibly changed according to customer requirements in the future.
R low-speed monitoring ▶ Determine the opening and closing of the safety door through hardware.
A Control ▶ Control tire pressure during the testing process. When using this institution, it is not possible to conduct pressure sealing tests
C Cleaning windows ▶ Window for regular cleaning of the drum surface.
B Explosion Monitoring ▶ Can monitor tire blowouts.
Surface temperature measurement of T tire ▶ The surface temperature of the tire can be monitored through an infrared thermometer.
S spindle oil lubrication ▶ The spindle lubrication can be switched from grease to low resistance oil lubrication.
Add outer cover skylight to L ▶ If the customer uses a bridge lifting method, an opening and closing can be added to the top of the outer cover.
O Console ▶ A control panel for operable devices.
M additional torque method ▶ Measurement method for measuring drum shaft torque. ※ The motor and drum are directly connected
G additional energy regeneration unit ▶ When the drum stops, an energy regeneration unit can be used.
E drive cabinet cooling ▶ Add cooling inside the drive cabinet.
H high-speed specifications ▶ The drum speed can beChange to 250km/h ※ The motor and drum are directly connected, and the drum is a steel drum
5、 Example of actual measurement data using standard tires according to ISO2850 regulations
This is the result of conducting three tests of forward and reverse rotation using standard tires. Both forward and reverse rotations have high reproducibility, with a standard deviation (σ) of ≤ 0.05N/kN.
6、 3 models with 8 options to choose from
There are three models of Ainde rolling resistance testing machine.
