This paper presents the responses of the railway vehicle and track components in terms of contact forces and displacements. The considered vehicle model is a five-DOF pitch-plane lumped parameter quarter car model supported on two-dimensional track systems comprising three layers. The car body is linked with the vehicle bogie through secondary suspension springs and damper elements, which is fu...

The user interface in a modern car is very comprehensive. Most of the essential functions are just a few centimeters away from the point where the driver holds the steering wheel, and are accessed by various combinations of touches and movements. The steering column switch is an effective way of bringing together functions which allow the driver to activate the direction indicator, control the ...

An Two wheel self supporting robot is design using IOC(Internet-on-a-chip) controller. The DC motor is controlled by PWM technique. In the existing system the robot were designed using tilt sensor, IR sensor, Attitude sensor and moving robot in a straight line. We propose a new design in two wheel self support robot using the principle of curvature technique, were a force that makes the robot t...

Multispectral image capture, unlike traditional RGB imaging, records the colour signals in a scene. Most available devices are either filter-wheel multiple exposure systems or point-measuring diffraction grating based devices. In this article we introduce a 2D matrix, full spectral, single exposure capture system – the Applied Spectral Imaging SpectraCube – which determines multispectral images...

This paper investigates the efficiency of a 2-period gait from the kinetic energy view-point. First, we formulate a steady 2-period gait for a compass-like bipedal robot by using a simple recurrence formula for the kinetic energy of an asymmetric rimless wheel. Second, we theoretically show that, in the case that the mean value of the hip angle is constant, the generated 2-period steady gait is...

Abstract As for the efficient and high-precision grinding of blades, it was studied that a flexible path planning method abrasive cloth wheel blades. In paper, based on modified Preston equation, radial material removal depth model is supplemented, which provides theoretical support establishment wheel. After obtaining envelope surface by double parameter sphere family method, deformation amoun...

Using the haptic modality to transfer information to the driver is recognized as a promising possibility in many in-vehicle applications. In the field of lane departure warning systems, several haptic warning signals were presented in the last years. The application of synthetic steering wheel torque or vibration informs the driver of an imminent lane departure. In this paper, an approach to cl...

We describe a device to measure blood perfusion for the human optic nerve head (ONH) based on laser Doppler flowmetry (LDF) with a flicker stimuli of the fovea region. This device is self-aligned for LDF measurements and includes near-infrared pupil observation, green illumination, and observation of the ONH. The optical system of the flowmeter is based on a Schlieren arrangement which collects...

For a linear model of active car steering a robust decoupling control law by feedback of the yaw rate to front wheel steering was derived earlier. In the present paper this control law is extended by feedback of the yaw rate to rear wheel steering. A controller structure with one free damping parameter k D is derived with the following properties: i) Damping and natural frequency of the yaw mod...

In this study, a low degree-of-freedom mechanical model of a rolling tire is constructed, in which the lateral deformation of the contact patch and tire carcass is considered. The so-called delayed contact patch model is implemented and combined with a simple tire carcass model. The interaction between the contact patch and the carcass together with the lateral mode of the attached suspension s...
