装载机前车架强度与局部焊接应力分析的中期报告 摘要： 本中期报告对装载机前车架的强度和焊接应力进行了分析研究，采用有限元分析方法对前车架进行模拟，得出了前车架在静态加载下的应力和位移分布，并进行了拟合和验证计算，验证结果表明该模型的可靠性和合理性。同时对前车架进行了局部焊接应力分析，通过分析焊缝处的应力集中情况，提出了优化焊接结构的建议。 关键词：装载机前车架；强度分析；焊接应力分析；有限元法；局部焊接 Abstract: This midterm report analyzes the strength and welding stress of the loaders front frame, simulates the front frame using finite element analysis method, obtains the stress and displacement distribution of the front frame under static loading, and performs fitting and verification calculations. The verification results show that the model is reliable and reasonable. At the same time, the local welding stress of the front frame is analyzed, and suggestions for optimizing the welding structure are proposed by analyzing the stress concentration at the weld seam. Keywords: loader front frame, strength analysis, welding stress analysis, finite element method, local welding.
