In this paper, a blackbox approach is carried out to model the nonlinear dynamic bushing model. One-axis durability test is performed to describe the mechanical behavior of typical vehicle elastomeric components. The results of the tests are used to develop an empirical bushing model with an artificial neural network. The back propagation algorithm is used to obtain the weighting factor of the neural network. Since the output for a dynamic system depends on the histories of inputs and outputs. Narendra 's algorithm of 'NARMAX' form is employed in the neural network bushing module. A numerical example and a vehicle simulation are carried out to verify the developed bushing model.

Detection and tracking are fundamental system-level issues in wireless sensor networks and military operations because they can provide very important measurements which help us to determine the method of reaction. All systems in the real world can't avoid inevitable errors which occurred in the observation samples. There are possible ways which can improve accuracy. This paper deals with methods to detect, evaluate and estimate all information of the devices given the current information with confidence. The primary objective of this research was to use different Kalman filters such as the Extended Kalman filter(EKF) and the Unscented Kalman filter(UKF) with purpose of evaluating them and finding the selective way to choose suitable filter based on given condition and requirement. It was performed with theoretical way and simulations. The results that will be discussed in this paper help to characterize the Kalman filters in application terms. The second goal was to implement the integrated ground and low altitude defense algorithms by using Kalman filters which satisfy the assumptions and qualifications.

An accurate model of the rubber bushing requires to capture the nonlinear and hysteretic behavior of the rubber. This paper presents a new modeling method for a bushing in the form of TSK(Takagi-Sugeno-Kang) fuzzy inference system. First, one-axis performance test using an MTS machine is done to describe the mechanical behavior of the bushing. The results of the test are used to develop an empirical bushing model using ANFIS. ANFIS(Adaptive Neuro-Fuzzy Inference system) is used to determine 45 nonlinear premise parameters and 1458 linear consequent parameters that describe the behavior of the bushing. The resulting fuzzy inference system is shown to satisfactorily represent the nonlinear behavior of the bushing.

Commercial vehicles arc mostly subjected to relatively rougher ground environment than passenger vehicles. Many driver's seats of commercial vehicles have suspension system with air spring and dampers. This Study is about optimization for connecting points of MR damper and Air spring. MR Damper Optimization Algorithm is used to SQP(Sequential Quadratic Programming) in ADAMS.
