| 摘要: | 本研究是蒐集市面上現有的減振材料以實場測試進行量測，比較其最佳的減振頻率，提出適合的材料，以期應用於實場上以減少勞工暴露於手-手臂振動的傷害。依據96年行政院勞工委員會進行工作環境安全衛生狀況認知調查，受雇者中有15.08%使用振動手工具，而雇主及自營作業者有18.62%使用振動手工具，勞工長期暴露於手-手臂振動易導致振動症候群，一旦病變顯現，將無法由藥物治療而復原。
以蒐集到27種材料，並利用ISO 8662方法進行實場測試，再利用ISO 10819方法高頻振動量小於0.6，中頻振動量小於1.0及第一顯著頻帶減振率小於0.6評估找出合適的減振材料。
研究結果得知以NEOPRENE-SBR及TPE材質製成的材料減振能力為優的佔14.3%，是所有材質內最好的，其次是PU材料製成的佔11.1%。在利用PUMA AT2680F測試時有CELLAMP M5130、CELLAMP M5110、CELLOMER S2120A、TPE 1020、TPE 5020、SA-0800、NX3-150、NX160RS、KSA700、K324、KHT、KHD、KSA300、KSA200、NEOPRENE-SBR達到ISO 108192的減振標準；利用HINTL TE5測試時有CELLOMER S2110D及NEOPRENE-SBR達到ISO 108192的減振標準。
The aims of this study were to collect available vibration-reduction materials, to test them in the field and to compare their vibration-reducing effects.
According to the survey of perceptions of safety and health in the work environment in 2007 in Taiwan, 15.08% of the employer used hand-held vibration tool, 18.62% of self-employer used hand-held vibration tool. Long term exposure to vibration generated by power hand-held tools may cause a series of disorders in the peripheral vascular, sensorineural and musculoskeletal systems of the hand and arm.
Using ISO 8662 method to test 27 kinds of materials in the field measurements and then using ISO 10819 method to evaluate the vibration-reduction effects were carried out.
The results indicated that materials made of NEOPRENE-SBR and TPE with excellent vibration-reduction capacity accounted for 14.3%, followed by PU materials accounted for 11.1%. When using PUMA AT2680F for test, CELLAMP M5130, CELLAMP M5110, CELLOMER S2120A, TPE 1020, TPE 5020, SA-0800, NX3-150, NX160RS, KSA700, K324, KHT, KHD, KSA300, KSA200, NEOPRENE-SBR achieved the ISO 108192 standards while using HINTL TE5 for test CELLOMER S2110D and NEOPRENE-SBR achieved the ISO 108192 standard. |
