摘要

手持式(hand-held)產品為滿足消費者使用需求，設計時常加上振動功能，除可提供使用者另一種提醒模式(振動模式)，亦可搭配軟體達到娛樂效果(力量回饋及觸動功能)。本論文研究以有限元素分析法模擬手機產品之振動器於四種不同擺放位置對振動量(vibration level, VL)之影響。實驗方法包含原始設計(對照組)及三種改良設計(實驗組A、實驗組B與實驗組C)。以Abaqus CAE軟體進行模擬分析三個測量點(P1、P2、P3)，以評估較佳之振動量。此外以實機模型進行驗證以分析X、Y、Z方向之震動量與總振動量(total vibration level, TVL)之變化。
模擬分析結果顯示，在最大外觀面(Z方向)之振動量與總振動量，於不同位置有顯著的變化，與實機試驗有相同變化趨勢。但在X、Y方向的振動量，於三個不同測量點之差異並不大。在三個實驗組中，實驗組C可有效提升總振動量，比對照組設計的改善幅度達143%。

Hand-held products were designed containing the vibration function to satisfy customer demand, such as the reminding mode (also called vibration mode) and amusement effect (force feedback and haptic functions). This thesis uses finite element analysis to study the four different mobile phone vibrator positions that affects its vibration level, VL. Experimental method includes the original design (called control group) and three improved designs (experimental groups A, B and C). Abaqus CAE software was used to simulate and analyze the vibration levels at three test points P1, P2, and P3. In addition, the real machines were designed and tested to validate the vibration level of X, Y, Z directions and the total vibration level, TVL.
Simulation results shows the maximum appearance surface (Z direction) and the total vibration the different test points have a strongly influence of the vibration level. However, the vibration level at the test points, P1, P2, and P3 of the X, Y direction is not obviously change. In the three experimental groups, the experimental group C can effectively enhance the total vibration level and the improvement up to 143% than that of control group.
