BM-VComputer pendulum friction coefficient testerworking principle:
This instrument is a power pendulum impact type instrument. It is developed based on the basic principle that the potential energy loss of the pendulum is equal to the work done by the rubber sheet at the end of the pendulum arm to overcome road friction when sliding on the road surface.

Technical parameters:
1. Weight of pendulum: 1500 ± 30g; Center of gravity distance of pendulum: 410 ± 5mm (self swing center distance);
2. Positive static pressure of rubber sheet on road surface: 2263g ± 50g (22.2N ± 0.5N);
3. Rubber sheet specifications: 76.2 * 25.4 * 6.35 ± 0.5mm or 31.75 * 25.4 * 6.35 ± 0.5mm;
4. The distance between the outer edge of the rubber sheet and the swing center is 510 ± 2mm;
5. Total weight of the instrument: approximately 12KG;
6. Swing accuracy of 0.1BPN, swing range of 0-150BPN;
7. Charging power supply DC 12V, 500mA;
8. Temperature measurement accuracy of 0.1 ℃, measurement range of 0-100 ℃;
9. Battery endurance of digital pendulum instrument: It can work continuously for 40 hours after being fully charged once;
10. Chinese LCD screen: 3.3-inch, displaying all parameters such as working status, swing value, temperature, battery voltage, and test times in Chinese simultaneously.
11. Working temperature of digital pendulum instrument: negative 15 to 65 degrees;
12. Dimensions of digital pendulum instrument (length * width * height): 600mm * 280mm * 600mm.

Structure:
1. Base: composed of T-shaped legs, leveling screws, and leveling bubbles, it plays a role in leveling and supporting the instrument.
2. Column: composed of a column, lifting mechanism, guide rod, and instrument handle, used for lifting and fixing the position of the pendulum head.
3. Release switch: a switch installed on the cantilever, used to maintain the horizontal position of the swing rod and release the function of swinging down.
4. Steering system: including fastening handle, swing shaft, steering knuckle and bearings, connecting swing, fixed position, ensuring free swinging in the swing plane.
5. Display system: The LCD screen directly reads the swing value.
6. Pendulum: It consists of upper and lower joints, pendulum rod, lifting handle, hammer shell, sliding block, and rubber sheet (76.2 * 25.4 * 6.35 ± 0.5mm or 31.75 * 25.4 * 6.35 ± 0.5mm). It has a specified torque on the swing center and a specified pressure on the road surface. The balance of torque between front and back, left and right is a measure of road friction coefficient.

summary:
With the rapid development of the national highway industry, higher requirements have been put forward for the research and testing methods of anti-skid performance of high-grade highways. In order to meet this requirement, our factory has developed a new generation of digital pendulum friction coefficient tester. The instrument is stable, reliable, easy to debug, simple to operate, and has a test data accuracy many times higher than pointer type. It can store 60 test results and measure road surface temperature. Equipped with a 12 volt charging power supply, this instrument can be used for 40 hours after being fully charged. It can be used both indoors and outdoors and is an ideal anti slip detection instrument for high-grade road construction and maintenance.
