探討EPS(Expandable Poly-Styrene;簡稱EPS)材料於防墜、防噪音性能及其應用性,研究內容係進行相關物理性試驗,撞擊試驗係以非鋼性物體模擬人體於固定高度墜落於不同K值之EPS試體上,測其試體及速度變化,而其撞擊瞬間之速度回歸方程式為ΔV ⃑= -0.0618K + 9.8793,緩衝時間回歸方程式為Δt=-0.0015K+0.0643;消音試驗係以EPS板罩住音箱以視其消音變化,實際測試不同頻率對於K值及厚度所降低之分貝數,結果顯示,隔音效果與厚度成正比,於500Hz時會發生共振現象,而在1000Hz時EPS材料有著絕佳的隔音性質。本論文之研究成果,可提供EPS在工地墜落及施工噪音防制等防災工程應用時之參考。
The study based on using EPS(Expandable Poly-Styrene) in falling and noising prevention by making several physical tests. The impact test is using a nonrigid object to simulate human body falling on EPS with different K value from fixed height. Using the result to observe the velocity change. The velocity equation isΔV ⃑= -0.0618K + 9.8793. The time equation isΔt=-0.0015K+0.0643. The noise prevention test is using EPS to cover voice box to observe the noise reduction. The experiment shows that the noise reduction has positive relation to the thick of EPS. Resonance occurs at 500Hz and EPS reduces the noise well and 1000Hz. The result of the study could be a guideline of EPS using in construction site to prevent falling and noise.
