查询词典 bending

In this paper the nonstationary vibration behavior of an unbalanced rotor system, which is assumed to be bending flexible but torsionally rigid, during acceleration or deceleration through the critical speeds is investigated. Influencing factors such as gyrascopic effects, external and internal damping, Supporting mass, damping and stiffness, asymmetry of the shaft crass section as well as anisotropy of the supports are considered.

在理论分析方面，本文考虑了转子的陀螺效应，内外阻尼，轴截面的非对称性，支承的貭量、阻尼、刚度和支承的各向异性等因素的影响，使用分析动力学，建立起严格的运动方程，并考虑了弯曲自由度与转动自由度间的耦合，因而能较精确地分析和描述转子通过临界点时的非定常振动和转速变化規律。

After the addition of carbon, the microhardness in the grain boundary is about 150 MPa higher than that in the grain. The fracture type of pure Mo is intergranular fracture, the grain boundary strength of Mo-C alloy is strengthened due to the addition of carbon and the fracture type is changed to transgranular fracture, transcrystalline fracture and a large number of cleavage planes and steps are observed on the bending fracture surface. But if the carbon content is too high, the carbide precipitation will be severe at grain boundaries and is deleterioated to the ductility of the alloy.

添加碳后，合金的晶界显微硬度比合金的晶内显微硬度高150MPa左右；纯钼的断裂方式以沿晶断裂为主，添加碳后，由于合金的晶界强度得到提高，合金的断裂方式变成以穿晶断裂为主，断口上有大量的解理面，具有明显的河流状花样和解理台阶，且塑性越好的断口，撕裂岭也越多；当添加的碳含量偏高时，在晶界处产生了大颗粒的碳化物，这种大颗粒的碳化物会降低合金的塑性。
