The invention provides a method and a system for acquiring a mechanical property distribution rule of an elastic rod. The method comprises the following steps: establishing a fractional order heat conduction model for an elastic rod, and establishing a motion model and a constitutive model without physical strength; performing dimensionless processing on the fractional order heat conduction model, the motion model and the constitutive model to obtain a control equation; and performing Laplace transformation on the control equation, and solving to obtain a mechanical property distribution result. According to the elastic rod mechanical property distribution rule obtaining method and system, the accuracy of the solving result of the elastic rod mechanical property distribution rule can be improved. 本申请提供了一种弹性杆力学性能分布规律获取方法和系统。方法包括如下步骤：针对弹性杆建立分数阶热传导模型，并建立不计体力的运动模型和本构模型；对所述分数阶热传导模型、所述运动模型和所述本构模型进行无量纲处理，以得到控制方程；以及对所述控制方程进行拉普拉斯变换，并通过求解得到力学性能分布结果。本申请的弹性杆力学性能分布规律获取方法和系统，可以提升弹性杆力学性能分布规律求解结果的准确性。
