Inter-hospital transport of premature infants is increasingly common, given the centralisation of neonatal intensive care. However, it is known to be associated with anomalously increased morbidity, most notably brain injury, and with increased mortality from multifactorial causes. Surprisingly, there have been relatively few previous studies investigating the levels of mechanical shock and vib...

To improve the response of an autonomous ground vehicle (AGV) as it seeks to complete an outdoor mission, the control system of the vehicle should vary as it encounters specific terrains such as sand, gravel, mud, or ice. To determine when to switch the control system it is beneficial to have accurate and fast online terrain classification. The earliest terrain classification algorithms were vi...

The vibration control of a construction vehicle must be carried out in order to meet the aims of sustainable environmental development and to avoid the potential human health hazards. In this paper, based on market feedback, the driver seat vibration of a type of wheel loader in the left and right direction, is found to be significant over a certain speed range. In order to find abnormal vibrat...

Feature extraction algorithms for vehicle classification techniques represent a large branch of Automatic Target Recognition (ATR) efforts. Traditionally, vehicle ATR techniques have assumed time series vibration data collected from multiple accelerometers are a function of direct path, engine driven signal energy. If data, however, is highly dependent on measurement location these pre-establis...

This paper uses robust pole assignment method to design an adaptive velocity and altitude tracking control algorithm for the longitudinal model of a wave rider configuration air-breathing hypersonic vehicle, which has strong coupling between structure, propulsion and aerodynamics. Base on the elastic hypersonic vehicle model CSUAL_GHV, the simulations using adaptive robust pole assignment contr...

The problem of optimal vibration control for vehicle active suspension systems under road roughness disturbance is considered. First, the models for two-degree-freedom quarter-car suspension system under road roughness disturbance are presented, and road disturbances are considered as the output of an exosystem. Then, the feedforward and feedback optimal vibration control (FFOVC) law for vehicl...

In this research, Ride quality of a three-axle truck is investigated to understand its vibration specifications and influence of it on special load. The truck is Benz 2624, and the load is rather sensitive to vibrations. The system is considered for an off-road duty. Hence, the vehicle is modeled as a nineteen-degree of freedom system and its equations of motion are derived by employing Lagrang...

The damping ratio of chassis suspension is a key parameter for damping matching of in-wheel motor vehicles (IWMVs). Because the motor is attached to the driving wheel, the initial design method of the damping ratio for traditional cars is not entirely suitable for IWMVs. This paper proposes an innovative initial design method of the damping ratio for IWMVs. Firstly, a traveling vibration model ...
