Surface modifications of metal discs in the form of parallel and radial grooves are investigated for acquiring enhanced performance against friction-induced noise. Experimental and numerical studies indicate that grooved surfaces are capable of reducing squeal noise, and the groove width significantly affects the squeal noise level. Moreover, a disc sample with parallel grooves distributed on only...
This paper reports a new uncooled optically readable infrared focal plane array (UOR-IRFPA), which is fabricated on a glass substrate. Compared with conventional UOR-IRFPA fabricated on a silicon substrate, visible light (readout light) can irradiate on visible reflecting layer through glass substrate and infrared light can directly radiate on infrared absorption layer from another direction. Therefore,...
