Abstract

Monitoring the translations of points on structures and machinery is an important procedure in industrial engineering. Two low-cost translation monitoring systems using electronic tachometers have been developed and tested at the University of Calgary. The systems use both network and nonnetwork (direct) methods to measure relative point translations with submillimeter accuracy. The systems are simple and efficient, requiring only one observer using normal surveying instruments. Two case studies undertaken by the authors are described, demonstrating applications of the new monitoring systems. The first study is the measurement of thermal growth of a rotating gas turbine/compressor system during startup. The thermal movements were measured and found to be consistent with their expected behavior to a precision of 0.2 mm. The second study is the measurement of point displacements on a concrete structure and test frame during a load test at the University's Civil Engineering Structures Lab. The translations measured agree with the theoretical values from a finite element analysis.
