fail-steady
解釋
故障狀態穩定的-
The combustor do n ' t fail if transient rise of temperature field is neglected, the stress field of combustor can n ' t cause gas film wall rupture. 2. combustor ' s creep and relaxation is calculated in steady temperature field, the results show that creep and relaxation is not main reason destroying combustor chamber
對穩態溫度場下的蠕變鬆弛計算表明,高溫下的蠕變鬆弛促使火焰筒的熱應力下降,在所考慮的條件下穩態溫度場導致火焰筒的蠕變變形不是火焰筒破壞的主要原因。 -
Steady state thermal analysis under natural convection boundary condition was performed. both the temperature distribution and the induced mechanical stress were calculated in this simulation. high stress area was found and the potential reasons which can cause packaging to fail were also discussed
具體內容包括: 1 .建立一款疊層csp / bga封裝的三維實體有限元模型,求解自然對流條件下的穩態溫度場分佈,並在此基礎上進行穩態熱應力和熱應變分析,找出由於溫度梯度在封裝內部引起的高熱應力區域,分析其可能造成的失效結果。
