Abstract


In mechanical transmission system, torque is one of the important mechanical parameters which can reflect the system property, and is an important parameter of rotary machinery power output. It is a basic load form of various working machines’rotation shaft,and is one of the important reference indicators when inspecting whether the product quality meets the design requirement. Armored vehicle power transmission system is the power source of armored vehicle driving, and the torque load condition of working shaft on different road surface has caused people’s attention all along. Through the study on armored vehicles torque load test and processing, obtain the torque load spectrum data when driving.It has great significance on testing whether the shaft parts meet design requirement, understanding and mastering the power transmission equipment operating conditions,analyzing and improving current serving equipments, increasing reliability and vehicle stereotype design,and occupies a pivotal position in life and strength reliability design of current serving armored vehicles.This paper widely consults relevant technical literatures and carries out digestion and absorption,and has designed one kind of dynamic torque remote sensing test device. In this system, torque data transmission uses wireless remote sensing technology, which solves the problems such as narrow space of armored vehicles, signal shielding and difficult transmission.Combining the device development process and the site vehicle testing under different speed and road conditions, this paper discusses basic principle and overall plan of vehicle’s dynamic torque test,software and hardware design of the test system, system anti-jamming technology, System calibration, processing and analysis program of torque data,and so on,in the end,we introduce the torque test situation of a certain armored vehicle,conduct signal processing with MATLAB, and obtain the real-time dynamic torque signal, power spectral density curve, load frequency figure, and so on.
