摘要
选择合适的可靠度理论,合理简化模型,对护理床抬背杆的可靠度分析非常重要。在受力最大的情况下,通过可靠度理论(改进的一次二节矩法)对简化模型进行可靠度分析,得到了可靠度指标。试验证明,根据改进的一次二阶矩法得到的结果更具有正确性、可行性,为护理床抬背杆的可靠度研究提供了依据。
It is important for the analysis of reliability of nursing sample raise-back bar to selectsuitable reliability theory and reasonable simplified model. In case of maximum force, reliability index can be produced by analyzing reliability of simplified model with reliability theory（ improved FOSM）. Experiment proves that in light of FOSM, more correct and feasible results could be obtained, which provides some basis for reliability research on nursing sample raise-back design.
