The hypersphere support vector machine is an efficient method to evaluate the state of mechanism. The state of Power-Shift Steering Transmission (PSST) is studied using hypersphere support vector machine. The theory of hypersphere support vector machine is researched and an evaluation model is developed. The generalization of the model is analyzed. The spectrometric oil analysis data are processed...
The hypersphere support vector machine is an efficient method to distinguish the state of mechanism. The state of Power-Shift Steering Transmission (PSST) is studied using hypersphere support vector machine and Principal Component Analysis(PCA) with spectrometric oil analysis data. The fundamental of hypersphere support vector machine and PCA is researched. The influence of model parameters for performance...
Based on the mathematical model of wet clutch engagement, a dynamic model of a tracked vehicle was developed by means of the software Matlab/Simulink. This model can be used to simulate the shift schedule, piston pressure and relative velocity. A two dimensional heat conduction model was also developed with reasonable selection of proper boundary conditions, contact pressure model and heat flux distribution...
This paper is aimed at the condition monitoring problem of the Power-shift Steering Transmission (PSST), a method of multiple out least squares support vector regression is developed which is applied to prediction of spectrometric oil analysis data. Radial Basis Function (RBF) is used is this algorithm. There are two parameters ?? and ??2. The selection of ?? and ??2 is studied using cross validation...
Support vector machine (SVM) is an efficient method for data mining of oil analysis. The principle and structural risk of SVM are described in this paper. And the structural risk is studied using oil analysis data. During the process, parameters determination is a very important part because parameters have great influence on the performance of SVM. We select the Radial Basis Function (RBF) as the...
This paper presents a study on steering power balance with a certain hydrostatic drive tracked vehicle as the objective. The influence of sideslip curve to the steering power is examined on the basis of analyzing the steering power of hydrostatic drive tracked vehicle. The variation relationship between speed and power on steering condition with no sideslip is obtained. It is indicated that the engine...
