摘要: 通过因子分析,确定了碰撞速度是影响冰箱抽屉碰撞噪音的最主要原因;依据经典力学牛顿第二定律,推导了滑轨抽屉碰撞速度的计算公式。实验结果显示出撞击速度与碰撞噪音之间的关系,并利用对数方程[A×ln(v+B)+C]拟合出预测公式。经过实验对照,拟合结果具有较高吻合度。在后续的冰箱滑轨抽屉设计中,结合理论推导公式及拟合方程可定量的预测抽屉碰撞噪音,在产品设计初期即可针对相应参数进行优化设计。

Abstract: Factor analysis confirms that impact velocity is the main factor affecting the refrigerator drawer impact noise. According to the second law of classical mechanics, the calculation formula for crash speed of drawer is derived. The relationship between impact velocity and impact noise is obtained experimentally, and we use the logarithmic equation [A×ln(v+B)+C] to fit the prediction formula. Comparing with the experiment, the fitting result has a high coincidence. Theoretical and fitting formulas can be used in the design of refrigerator drawers to quantitatively predict the impact noise. The corresponding parameters can be optimized at the beginning of product design.
