四柱液压机立柱强度计算的注意事项:
Notethe calculation strength of column hydraulic machine:
第一:在应力比较集中的地方,或者是弯矩比较大的地方,主要是在横梁的螺母这一块,四柱液压机立柱的最大负荷和离心力进行计算。
First:in stress concentration areas, or relatively large bending moment, is mainly inthe beam of this nut A, four column hydraulic press(www.yxpic.com) column of maximum load andcentrifugal force were calculated.
第二:我们要知道,如果说拉深的应力太大了,那么就会有疲劳的损害出现,所以我们要把反复的承载算进去,如果是长时间的高强度受力那威力四柱液压机械液压机会出现裂纹的。
Second:we want to know, if drawing stress is too large, then there will be fatiguedamage, so we have to take repeated load into account, if it is high intensityand long time stress crack of the power hydraulic machinery hydraulicopportunity.
第三:由于没有典型载荷方案,对于疲劳设计的计算这种最有效的计算方法带来了困难,在计算立柱承受力时,很大一部分是根据经验来的,所以在向技术人员阐述时要说详细、清楚。
Third:because there is no typical loading scheme, calculation method for fatiguedesign of this calculation is the most effective poses difficulties in thecalculation of upright bearing capacity, a large part is according to theexperience, so to the elaboration of technical personnel to say detailed,clear.
