Source Wave Analysis of Impact Force on Wood Based Panel Floor

Abstract

Source wave analysis technique was applied to analyze the impact forces on wood based panel floors. The peak level and contacting interval of the source wave at impact points were evaluated for the plywood floor and also for the floors finished with two different materials, a vinyl-chloride sheet and a needle point carpet. In the case of the plywood floor, the impact forces by flexible bodies, such as rubber shoes stepping and rubber ball dropping, have almost the same characteristics as those in the case of concrete slub floors. The characteristics of impact force on the plywood floor by rigid bodies, such as high-heeled shoes stepping and mini-tapping machine impact, differ from those on the concrete slub floors. The finish materials lengthen the contacting intervals for the rigid body impact in the order of vinyl-chloride sheet and needle point carpet, although they have no influence on the contacting interval for the flexible body impact.
