在液晶電視的產品設計,腳架(neck)的設計是很重要的,它會影響電視的平衡,不穩定的平衡設計容易造成液晶電視的振動與傾倒,造成產品的破壞或因掉落造成消費者人身的受傷。傳統上腳架的設計都是採用壓鑄件,因應輕薄等設計趨勢,採用鈑金件沖壓方式製作腳架去取代壓鑄件的方式,本文研究主要在利用『有限元素法』模擬不同補強肋形狀的腳架設計,進行模態及暫態分析。本研究個案結果顯示,從暫態分析模擬與利用推力計施加20N作用力於液晶電視上之實測值驗證,水平肋(Type 3)的補強比起無補強肋(Type 1)及垂直肋(Type 2) 補強能有效地降低時間衰減及改善振動的現象。
In the numerous liquid crystal product design, the neck design is very important. It will affect television's balance, the unstable balanced design easy to create liquid crystal's falling and to cause the product broken or falls to make consumer being injured. The major part of neck designs are use die casting, mainstream is light and thin design, so this article will to use punch method to manufacture neck to replace die casting method. This study is mainly using “finite element method” to simulate different strengthens form design and process in Modal analysis and Transient analysis. The result of research showed that from the transient analysis simulation and use of applied 20N force on LCD TV. Type3 is better than Type1 and Type2,it can effectively reduce time and improve the vibration attenuation phenomenon.
