【摘要】：针对实际应用设计了一种加载装置,通过使用杠杆加载,实现采用较低吨位液压作动筒来达到大吨位加压载荷要求。采用Abaqus有限元分析了直接接触连接设计下,装置加载能力与设计目标的偏差。通过现场实验测试,对比了计算分析结果与实际测试结果的吻合程度,并对装置进行了结构优化。研究发现:杠杆偏压对目标载荷的实现影响十分严重,其导致杠杆力臂比例发生变化;球形铰能有效消除支点偏心影响,实现目标加载要求。本文的研究为杠杆加载的深入研究提供数据支持和理论依据。
[Abstract]:A loading device is designed for practical application. By using lever loading, the lower tonnage hydraulic actuator can be used to meet the requirement of large tonnage pressure load. The Abaqus finite element method is used to analyze the deviation between the loading capacity of the device and the design objective under the design of direct contact connection. Through the field test, the results of calculation and analysis are compared with the actual test results, and the structure of the device is optimized. It is found that the influence of lever bias on the realization of target load is very serious, which leads to the change of lever arm ratio, and the spherical hinge can effectively eliminate the eccentric effect of fulcrum and meet the target loading requirements. The research in this paper provides data support and theoretical basis for the further study of lever loading.
