【摘要】 复合材料储能飞轮转子的内部主要应力是环向应力和径向应力。纤维增强复合材料飞轮转子的径向强度远小于环向强度,径向应力是导致储能飞轮分层失效的一个重要因素,结合缠绕材料的刚度、密度以及缠绕角对应力分布和储能总量的影响,采用过盈装配的多层飞轮结构可显著降低其径向应力,而用张力缠绕的储能飞轮外侧缠绕张力大于内侧,效果与过盈装配的多层飞轮相同,且制作较为简便.更多还原

【Abstract】 The main stress of a rotating composite flywheel rotor are hoop stress and radial stress, the (rotors) radial strength is much lower than the hoop strength. The rotor is often damaged with delamination by the radial stress, considering the influence of the stiffness, density and ply angle on the stress distribution and the total stored energy, this paper thinks that the multi-ring assembled by press fitting reduces the radial stress, but the effect of a rotor fabricated by tension winding process that the peripheral winding tension is higher than the inner winding tension.It is same with the press fitted rotor and the process is more simple.更多还原
