Research on Dynamic Braking Force Calibration Device for Roller Opposite Force Type Brake Testers
According to the requirement of national metrology technical code for dynamic braking force verification of brake test bench,a dynamic braking force verification device based on standard wheel is developed.Without changing the structure of the vehicle itself,force sensors are installed on the standard wheel through special mechan-ical design,and WiFi wireless data transmission is adopted.The test results show that the verification device can ac-curately measure the dynamic braking force of the cylinder,avoid the problem that the cable may be entangled when the wheel rotates,and has the advantages of convenient operation,good data stability and high repeatability,which is an ideal solution to the dynamic braking force verification.
