【摘要】 本文首先提出了修正的曼耐尔假设,从而克服了曼耐尔假设的一个明显的缺陷。进而以此为基础,推导了机械零件所承受的各种变载荷的等效载荷计算公式,并对其正确使用提出下必要的要求。文中还进行了等效载荷的实例计算和试验验证。结果表明;本文提出的公式有一定精确度,可以在实际中使用。更多还原

【Abstract】 A corrected Miner hypothesis has been developed to overcome an obvious defect in Miner hypothesis. The authors, based on this, give out the calculating formulas of the equivalent loads for machine elements which bear different kind of variable loads and put forward some requirements to use it correctly. A practical example of equivalent load is calculated and its result is examined by test. It shows that the formulas are possessed of certain accuracy and may be used in practical engineering.更多还原
