摘要
本文基于层合板理论,结合各向同性材料稳定杆的刚度公式与纤维复合材料平板等效剪切模量的公式,推导出了复合材料稳定杆的刚度理论公式。接着,通过有限元模拟分别对金属与复合材料稳定杆进行刚度、强度分析。在相同刚度的情况下,复合材料稳定杆的强度完全满足要求,验证了复合材料稳定杆的可靠性,并且复合材料稳定杆相比金属横向稳定杆重量减轻52.2%,最后将刚度分析结果与理论计算进行对比,结果误差小于5%。本研究可为该类复合材料稳定杆的设计提供了一定的理论参考。
Based on the laminated plate theory, combined with the stiffness formula of the isotropic material stabilizer bar and the formula of the equivalent shear modulus of the fiber composite plate, the theoretical formula of the stiffness of the composite stabilizer bar is derived. Then, the stiffness and strength of metal and composite stabilizer bars are analyzed by finite element simulation. In the case of the same stiffness, the strength of the composite stabilizer bar fully meets the requirements, which verifies the reliability of the composite stabilizer bar, and the weight of the composite stabi-lizer bar is reduced by 52.2% compared with the metal stabilizer bar. Finally, the stiffness analysis results are compared with the theoretical calculation, and the error is less than 5%. This study can provide a theoretical reference for the design of this kind of composite stabilizer bar.
