The forces generated by water-square cylinder interaction have been investigated experimentally. Three kinds of square cylinder models of 50 mm, 75 mm and 100 mm width were used. The square cylinder with two endplates was oscillated horizontally in standing water by mechanical oscillation machinery. The force was measured by means of a quartz force transducer. Period parameters ranging from 0.2 to 1.8 and Reynolds numbers from 450 to 51460 were covered in the investigation. The results have shown that the wave forms of the forces depend on period parameters and Reynolds numbers, and the force amplitude coefficients are determined only by period parameters.
