根据某汽车钢板弹簧相关参数和分析结果，用有限元软件ANSYS设计优化了一种玻璃纤维增强树脂基复合材料（CFRV俗称玻璃钢）板弹簧来代替原钢板弹簧，并对其动态特性及结构应力分布进行有限元分析，结果证明该复合材料板弹簧应力更低，固有频率更高，不计吊耳时弹簧重量减轻了约75％。 相似文献

This research aims to study the feasibility of repair and strengthening of timber cantilever beams used in historic buildings. It is conducted to investigate the feasibility of using different valid materials and techniques to repair and strengthen timber cantilever beams in new and historic timber buildings. The study is performed in terms of structural performance as well as historic and architectural values. An experimental program of several different materials and techniques is executed. The results are driven in terms of initial cracking load, crack propagation for the tested samples at different loading stages, deflection values, and failure load for each repaired or strengthened material and technique. The main variables are timber types (new and historic), repair and strengthening materials (steel plates, Glass Fiber Reinforced Polymer wrap, and Carbon Fiber Reinforced Polymer laminates), repair or strengthening techniques (near surface mounted and externally bonded system), and cantilever length (1000 and 1250?mm). Test results indicated that using steel plates, glass fiber wrap, and carbon fiber laminates increases the value of failure loads and decreases the deflection at both; repaired and strengthened timber cantilever beams compared to control beams. 相似文献

GFRP抗浮锚杆在基础底板中的锚固性能现场试验研究 总被引：2，自引：0，他引：2
通过现场拉拔破坏性试验,测得不同直径的GFRP抗浮锚杆在基础底板内的极限承载力和滑移量,并与实际工程中不同形式的钢筋抗浮锚杆作比较,分析其承载性能和粘结特性。研究表明,在相同的混凝土强度与养护条件下,相同直径的GFRP抗浮锚杆的极限承载力、平均粘结强度与钢筋抗浮锚杆相比较高,且GFRP抗浮锚杆的变形能够满足实际工程需求,充分验证了GFRP材料用作抗浮锚杆的先进性与合理性。基于试验结果与理论分析,给出了GFRP抗浮锚杆与基础底板的最佳锚固面积,并提出了计算公式。 相似文献
