壓縮彈簧在工業上應用非常普遍,其中以彈簧力大小作為彈簧設計主要之目標。例如,在400G的高速傳輸通訊裝置中(32芯MPO介面裝置),就需要壓縮彈簧提供穩定的接觸力。因此,除了有正向彈簧力之要求外,其側向彈簧力之大小也會影響光纖傳輸是否穩定特別是光反射率。本研究以模擬及實驗兩種方式探討不同彈簧設計參數及拘束條件對壓縮彈簧彈簧力影響。透過有限元素分析及彈簧力量測實驗,驗證彈簧下端節點的總反作用力作為彈簧力大小之判斷依據,並進一步探討在不同拘束條件與設計參數的設定下,彈簧力大小之變化情形。研究結果發現最多,在特定參數下可能造成彈簧側向力達到132%的差異。
Compression springs is very common in industrial applications, with spring force as the main target of the spring design. For example, inside a 400G high-speed transmission communication connector (32-multi-fiber MPO connector), a compression spring is required to provide a stable contact force. In addition,the requirements of the vertical spring force, the side spring force will also influences of the optical fiber transmission is stable, especial light reflectivity. This paper main study the influence of different spring design parameters and boundary condition on the spring force of compression spring by simulation and experiment. Through the finite element analysis and spring force measurement test, the total reaction force of the lower end node of the spring is verified as the basis for the determination of the spring force. And further explore the different boundary conditions and design parameters set, the spring force changes. The results of the study found the most, under the specific parameters may cause the spring lateral force increased by 132% .
