【Abstract】 To measure oil film thickness in mechanical equipment,an ultrasonic film thickness measurement system is designed based on ultrasonic reflection coefficient method. The certain human-computer interaction function on the basis of μC/OS-II and serial port control function of the host computer are implemented in this system,and the measurement of the simulated static oil film structure is completed. The relative error of the measurement results is less than 5%,which proves the feasibility of the ultrasonic film thickness measurement system.更多还原
