根据苹果振动试验结果，得出了损伤与振动加速度、振动时间、承载重量之间的多元线性回归方程。通过对这些数学模型的分析，说明了几种常用损伤评价指标的合理性和可比性，为预测振动损伤提供了依据。在相关分析中提出了用粘弹特性评价机械损伤的新方法。 According to the apple vibration test results, the multiple linear regression equations between the damage and the vibration acceleration, the vibration time and the bearing weight are obtained. Through the analysis of these mathematical models, the rationality and comparability of several commonly used indexes of damage evaluation are illustrated, which provides a basis for the prediction of vibration damage. In the correlation analysis, a new method for evaluating mechanical damage using viscoelastic properties was proposed.
