Аннотация: This paper outlines the study of the causes of the relative error Δ in braking-force metering FT using the noncontact magnetostrictive method. The study has been carried out on the roller brake testers used for monitoring a technical state of a vehicle brake system. The authors suggest that the metering error Δ depends on the gap δПоказать полностьюC formed between the measuring and magnetizing coils of the sensor and the surface of the shaft on which the magnetostrictive sensor is mounted. Based on this assumption the experimental study is conducted to reveal the dependence of the relative error Δ of the gap δ C that produce a shaft beat δ max inside the sensor. The results of the study indicate that when the shaft δ max = 0.2 mm, the metering error of brake force is Δ = 1.4 %. The given value of the relative error Δ of the braking-force metering does not exceed the maximum permissible value Δ = -3%. When the shaft beat δ max increases inside the sensor, the relative error Δ also increases. © Published under licence by IOP Publishing Ltd.
