bump stress 中文意思是什麼
bump stress
解釋
撞擊應力-
The ansys, a kind of fea program, was used to build model of small carriage. the procedure of gantry beam bump with secondary beam of bridge was reappeared by running nonlinear calculation and loading program which was written by apdl program language. the closest deforming result was gotten, and the deforming of main beam, secondary beam and end beam and inner stress distribution status were calculated
採用大型三維有限元軟體ansys對該起重機以及小車架等進行了建模、應用apdl語言編寫加載程序、進行非線性計算，再現龍門橫梁與起重機副梁碰撞過程，最後得到與實際變形結果最接近的一種狀態，得出起重機橋架主梁、副梁、端梁的變形以及其內部的應力分佈情況。 -
Practices on dynamic prevention and control of pressure bump in high stress zone of sanhejian mine
三河尖煤礦高應力區沖擊礦壓動態防治實踐 -
The stress of horizontal working states is bigger than others, and the maximum stress attaches to 540 mpa. only considering static strength, the bump auto satisfies command
水平工況應力較大，最大應力為540mpa ，單從靜強度方面考慮，該泵車滿足強度要求。 -
Statistic stress dangerous positions of bump on different working situations are got by generally analyzing all of the data. the working frequencies on different working situations are gained during the course of dynamic stress analysis, at the same time they are compared with the results of the bump hydraulic system measuring experiment, they are quietly consistent with each other. the main aim at analysis of the bump inherent frequency is to get its first frequency, which is used to find out the reason why the bump vibrates so serious
在進行靜應力分析中，計算出該型泵車所測工況所有測點的靜應力，通過對所有數據綜合分析之後，得出該型泵車在工作時不同工況的靜應力危險部位；在進行動應力分析過程中，分別求出不同工況的工作頻率，並與該泵車液壓系統測試實驗分析結果進行比較，二者結果比較吻合；對泵車進行固有頻率分析的主要目的是求得該型泵車的一階固有頻率，以尋求該泵車振動較大的原因。
