Abstract

Since moving pavement complex and changeable, tracked vehicle in the process of moving, balanced elbow withstand and pass alternating loads, seriously affect the life of the system of armored vehicles action. Domestic load testing and identification of armored vehicles are still in the phase of theoretical research, load data armored vehicles run by actual test, and load calibration and identification of major significance. In this thesis, a tracked infantry fighting vehicles for the study, the main study load identification characteristics of the equilibrium elbow. Thesis by theoretical studies and experimental validation of two parts. Theoretical aspects of load identification technology in-depth study to determine the balance of load identification method of the elbow. Test aspects of the six-component balance elbow by the identify and encode spectrum. In this thesis, made the following work: 1. Introduces the research status of force identification, summarizes the overview of the armored vehicles set spectrum; dynamic load identification theory and research methods, frequency domain and time-domain method theory-depth analysis, and the frequency domain method to determine the load identification method. Balance the structure of the elbow, the use of the PROE modeling software to establish a balanced three-dimensional model of the elbow, and the model import ANSYS12.0 modify, impose constraints and load by defining material properties, meshing, finite element model analysis, to get the balance elbow load and load in three directions and other effects of stress cloud, and extract the equivalent stress value of the measured points. First force to balance the elbow analysis and the establishment of a mechanical model, the arrangement of the measuring point and the strain gauge Bonder position, followed by the introduction of load calibration test programs and the process by different loading measuring point load calibration data and calibration data for in-depth analysis. Through different roads with different speed sports car test measured load data acquisition armored vehicle balance elbow; pretreatment data points of stress - time history using matlab signal processing software and programming on the the load identification model established balance elbow load identification, load and torque curve, and the preparation of the load spectrum, provided the basis for the estimates of the structural design and fatigue life; brief introduction to balance the elbow load identification method of neural network analysis of the advantages and disadvantages, and this article identification methods were compared to verify the rationality and feasibility of this method.
