Discussion of Errors of a Recommended Standard Resistor-Noise Test System

UML is employed to greatly improve the development speed and quality of embedded system and to raise the reusability of the system. The design concepts are shown graphically, which is helpful for the intercommunication of people from different fields. Easy intercommunication is surely beneficial for the development, maintenance of the system and the design of subsequent production line. The paper analyzes the process of applying UMB to the embedded system and the ways of modeling through the analysis of a multiple noise test system.

Hot-stamped high strength steel (HSS) is widely used in body structure as a solution for weight-reduction of automobiles. In order to realize fast field measurement of mechanical properties of hot-stamped HSS parts, a magnetic Barkhausen noise (MBN) test system was developed. The system was used to measure hardness of hot-stamped bumper beam and strip with tailored properties. Results show good precision and convenience of the MBN method.

Electromechanical Equipment

Noise test system model of current mechanical and electrical equipment is backward, which is easy to cause low test precision and long time-consuming problems. The afterward noise reduction work cannot be carried out smoothly. For this reason, a new noise test system for airborne electromechanical equipment is designed. The system is based on FPGA and MCU, including the system of power supply, speed sensor, noise sensor and so on. According to the noise measurement algorithm formulated by the International Electrotechnical Commission (IEC), the calculation of frequency and time weights in noise measurement is digitized. The digital processing algorithm of 1/3 octave spectrum analysis is combined to realize the noise test of airborne electromechanical equipment. The experimental results show that the designed system has strong anti-interference, high accuracy of noise testing, fast testing speed and conducive to the implementation of noise reduction work in the later period.
