Abstract

This paper describes the design, development and implementation of a multitasking computer aided data acquisition, control and analysis system(CADACAS) for remote condition and performance monitoring of reciprocating seal of an aircraft landing jack.

The condition monitoring is effected by a remote inspection technique which employs a computer controlled miniaturised charge couple device(CCD) camera and fiber optic aided inspection unit. This provides an in situ performance and behavioural observation of the seal. The load conditions and motion of the seal are monitored by specially designed loadcell and displacement transducers.

The CADACAS provides all the required fast data acquisition and analysis necessary for result interpretation. It is interconnected to a Packet Assembler Disassembler/CPSE network for communication with the mainframe and other shared peripherals. The network allows the data acquired to be used for advanced analysis and graphics. The same system is used for nonlinear finite element computer modelling of the reciprocating seal.
