實木家具力學功用與選材目標剖析毛衛國徐偉“,黃瓊濤2,唐先良3,吳才智1(1.南京林業大學家具與工業設計學院,南京210037;2.廣東省宜華木業股份有限公司;3.臺州市玉環縣楚洲人才科技立異服務中心)家具構件按結構分成支承型和銜接型構件,并進行力學功用剖析,結果表明:不同構件受力狀況不同,對木材硬度、尺度穩定性、握釘力等要求也不同。確認了不同構件各功用間的相對重要性,并在家具常用樹種力學功用剖析基礎上,對木材各功用進行了等級區分,數控砂邊機足球比分网為實木家具選材提出了功用要求和目標主張,實現木材在實木家具中的合理利用。

  載荷是木工平刨機效果于結構上的力,分為外力和內應力:外力是經過外在物體效果到結構上的力,包含效果力和支反力;內應力是結構構件內部發生的反抗外載荷的力m.家具作為長時間與人、物、環境交互的物件,在運用中會遭到各種形式的外載荷,如靜載荷、沖擊載荷、循環載荷等。因為木材自身的特性,家具木材內部在長時間反抗外力過程中會發生應力疲勞、變形乃至損壞等。
