目的：分析护理神经内科老年患者存在的安全隐患和防范对策。方法：对照组患者行常规护理，观察组患者行常规护理联合安全隐患护理，对其进行护理防范措施。比较两组患者发生不良事件情况及护理满意度。结果：观察组患者发生不良事件情况（8.0%）显著优于对照组（28.0%），差异有统计学意义（P＜0.05）；观察组护理满意度（94.00%）明显优于对照组（76.0%），差异有统计学意义（P＜0.05）。结论：对神经内科老年患者行安全隐患护理，对存在的隐患进行分析排除，采取积极防范措施，可有效减少不良事件的发生，利于患者康复，提高患者的满意度，值得临床推广。

The steering wheel of a light truck has a jitter problem in the idle condition. We used modal test to analyze the jitter reason under idle condition. It is found that the modal frequency of the steering wheel is close to the second order ignition frequency of the engine so the resonance of the steering wheel appears. In order to reduce the steering wheel vibration, we combined with the finite element analysis method and sensitivity analysis method. We adjusted the structure of the steering wheel and the thickness of the instrument panel beam to optimize the structure, thereby changing the natural frequency of the steering wheel. Measures works and the natural frequency was far from the second order ignition frequency of the engine. Finally, the effectiveness and rationality of the improvements were verified through tests.
