| Abstract: | In order to prevent the problem of brake safety caused by the excessively thin nonmetal friction plate, the design of nonmetal friction plate real time excessive thinness detection system on truck brake drum is proposed. Firstly, the analysis of nonmetal friction plate is conducted based on the entire contact lining-drum theory and practical applications. Secondly, three pairs of pre-embedding detection contacts are designed according to the analyses. Finally, the excessive thinness detection system is designed based on AT89C51, auxiliary LCD1602 and amplifier management module. The whole design is effective in practical applications. The effective alarm rate is over 98%. |
