Strength of Composite Laminates Containing Holes and Subjected to Complex Loading Conditions

Abstract: Stress and failure analyses of composite laminates containing holes are presented. Both the finite element method (FEM) and an analytical method, based on complex stress functions, are used to determine the stress distributions around the holes. The Point Stress Criterion (PSC) and the Damage Zone Criterion (DZC) are used to predict the tensile strength of test specimens subjected to complex loading conditions. A comprehensive test program was carried out to establish criteria parameters and to generate data to validate the stress and failure analyses. For this purpose a special test fixture was designed. Good agreement between predicted and measured results was found.

Airbag fixture for motor vehicles has gas generator and roof-mounted airbag flow-interconnected by tubular element which represents part of vehicle's support structure

Abstract: The gas generator(5) and roof-mounted airbag(2) are flow-interconnected by a tubular element which represents a part of the vehicle's support structure. The tubular element has at least one opening in its generated surface providing a connection for the airbag, and has a plug located before and after the airbag connection. The tubular element may form the A-column(3) of the vehicle and preferably forms also a section of a roof support(4) connected to the A-column. The gas generator is fitted on the lower section of the A-column.

Instrument display system for vehicle

Abstract: The vehicle is fitted with a number of sensors to monitor set parameters on the vehicle and power train. A logic system processes the signals and activates displays. The logic system decides a priority for the displays and delays some non essential indicators if the vehicle is in a situation which demands attention by the driver. This is determined by programmed control fields and by grouping the sensors in priority sets. The indication of some parameters eg. low washer fluid, is delayed eg. if the vehicle is being reversed, if the driver changes torque above a set rate, during braking etc. Non essential indicators are activated eg. when the vehicle is being driven at a steady speed along a straight road.

Comparison of Automotive FMCW and OFDM Radar Under Interference

Abstract: Automotive radars are subject to interference in spectrally congested environments. To mitigate this interference, various waveforms have been proposed. We compare two waveforms (FMCW and OFDM) in terms of their radar performance and robustness to interference, under similar parameter settings. Our results indicate that under proper windowing both waveforms can achieve similar performance, but OFDM is more sensitive to interference.
