The influence of geometric size, material properties of the slabs, inhomogeneous subgrade, sleeper beam and bituminous overlay on the bending stresses and deflection is investigated.
分析中包括了搭板的几何尺寸、材料因素、地基非均匀、枕梁及沥青加铺层对搭板弯拉应力及变形的影响。
In the prediction of sleeper radiation noise, the finite element beam model of sleeper is more suitable.
最终得出在预测轨枕辐射噪声时，轨枕梁有限元模型更加适合。
We consider each sleeper as an abutment of opposite forces, rails on horizontal sleepers as a mock dispersed elastic ground beam model and trains as moving load on beams.
将每根枕木考虑成一个支座反力，将横向枕木支承的钢轨模拟成离散的弹性地基梁模型，将列车考虑成一个作用在梁上的移动荷载。
Sleeper is regarded as a finite long beam on continuous elastics base. The relation between rail forces and sleeper displacement is established by analysis of sleeper forces.
