Design Construction

The Louisiana Transportation Research Center has recently completed the construction of a full-scale pavement test facility using the accelerated loading facility (ALF) machine. This facility contains nine pavement test sections, 12-m (38-ft) long and 3.66-m (12-ft) wide that are loaded by the ALF machine with loads ranging from 34.71 to 111.25 kN (7,800 to 25,000 lbf) on a dual-tire assembly. The advantage of this testing facility is its ability to cause a pavement to fail in a short period of time. In addition, the data acquisition methods and instrumentation used in this testing facility allow researchers to obtain reliable and representative performance data. The first test section has been loaded to failure and a preliminary analysis of the data is completed. VESYS 3A-M, a microcomputer version of the VESYS series, has been selected for the analysis due to its ability to predict damage and its flexibility. The analysis consists of the primary response analysis to determine strains, stresses, and deflection of the pavement and damage-prediction modeling that includes rutting, fatigue cracking, and roughness. The analysis was conducted by comparing the data obtained from field with that predicted by VESYS 3A-M. The performance data obtained from the field include fatigue cracking, rutting, and roughness. The analysis showed that VESYS 3A-M outputs are in good agreement with those obtained from the field.

Thin Walled

A nonlinear analysis procedure is validated in this paper to predict deformation response, up to collapse, of thin-walled Liquid Metal Reactor (LMR) piping elbows. Nonlinear shell analysis predictions are compared with experimental measurements of two full-scale large diameter (406 mm), thin-walled (D/t = 38), piping elbows tested at room temperature and at an elevated temperature in the Multi-Load Test Facility (MLTF) at Westinghouse. The overall and local deformation predictions agree very well with the measured deformation responses up to 60 percent of the measured plastic collapse moment, Mpce. The analytical-experimental correlation is reasonable up to 0.8 Mpce. At higher load levels the correlation is not as good; at collapse the analysis overpredicts measured deformations by as much as 30 percent.

Design Construction

To enhance its competitive edge in producing highly contamination-sensitive space systems, TRW has recently designed and constructed a large spacecraft assembly and test facility that is fully cleanroom compatible. Features of this facility include a large assembly and test area and a smaller support room that have HEPA-filtered vertical flow, dedicated staging areas for garment application, storage, and equipment preparation, and an automated cleanroom monitoring system (CRMS). A description of the design, construction, and certification process is given. Operational data from the CRMS and lessons learned are also presented.

This paper outlines the major design considerations and development experience of a 12,500-hp dual-shaft gas turbine. The unit uses an aircraft derivative gas turbine as the gas generator and is designed to operate in an attended or unattended station without external electrical power above 60 per cent of design speed. Proven power turbine design concepts were combined with the advantages of a variety of highly developed gas generators to produce a reliable machine which could be introduced with a minimum of development time. A special test facility was constructed to subject the unit to a full load test under conditions which simulated field operation.
