Root cause and vibration analysis is applied to a veneer peeling lathe to increase its efficiency and reduce wood waste. Excessive veneer thickness variations, repetitive damage of machine component and high vibration levels of the lathe are identified as interrelated issues. A root cause analysis is conducted to finally select both design and operating factors, which were then investigated to quantify their effects on the vibratory lathe response and process efficiency. On-site vibration measurements for different operating speeds, cutting tool conditions and log sizes are analyzed from RMS, kurtosis and crest factors for a 95% confidence interval. Based on the statistical significance, the effect of the operating conditions on the vibration energy level and impulsivity of the lathe is obtained. The analysis confirms that (1) the vibration level of the peeling process is significantly affected by the operating speed and cutting tool condition; (2) the signal impulsivity characterized by kurtosis varies with the process speed; and (3) the log size affects process efficiency. In addition, finite element modal analysis is applied to the lathe carriage structure to identify whether a transient resonance occurs during the peeling process. Finally, the study recommends the optimal lathe operating speed found for reducing vibration levels and incomplete log peeling.

对单板去皮车床进行根本原因和振动分析，以提高其效率并减少木材浪费。单板厚度变化过大，机器部件的重复损坏以及车床的高振动水平被认为是相互关联的问题。进行根本原因分析以最终选择设计和操作因素，然后对其进行研究以量化它们对振动车床响应和过程效率的影响。在RMS，峰度和波峰因数的95％置信区间内分析了不同操作速度，切削工具条件和原木尺寸的现场振动测量结果。基于统计意义，获得了工作条件对车床的振动能级和冲量的影响。分析证实：（1）剥皮过程的振动水平受操作速度和切削工具条件的影响很大；（2）以峰度为特征的信号冲动随处理速度的变化而变化；（3）日志大小影响流程效率。此外，对车架结构进行了有限元模态分析，以确定在剥离过程中是否发生瞬态共振。最后，研究建议了最佳的车床运行速度，以降低振动水平和不完整的原木剥皮。有限元模态分析应用于车架结构，以确定在剥离过程中是否发生瞬态共振。最后，研究建议了最佳的车床运行速度，以降低振动水平和不完整的原木剥皮。有限元模态分析应用于车架结构，以确定在剥离过程中是否发生瞬态共振。最后，研究建议了最佳的车床运行速度，以降低振动水平和不完整的原木剥皮。
