查询词典 tenons

By comparing the value obtained by the ANSYSs calculation with data from experimentation, it arrives at a conclusion that the finite element model of nonlinear analysis of prestressed simple concrete girder with nobonded tenons is accurate and the method of simulant analysis is feasible.

最后，将ANSYS仿真计算结果与试验结果进行比较，表明本文建立的无粘结预应力混凝土简支梁有限元模型的正确性、仿真分析方法的可行性。

It is understand that the performance of prestressed simple concrete girder with nobonded tenons that is under the loading through the simulant calculation of this grider, which is in the way that researching stress, strain, sections distortion, relation of loading-deformation, crack and ect.

通过对有限元模型的全过程仿真分析，考察了无粘结预应力混凝土简支梁的应力和应变的变化状况、截面变形状况、荷载-挠度关系、裂缝变化过程等，从而了解了无粘结预应力混凝土简支梁的受力性能。

When moving furniture, things in the chest should be moved out previously. Take and put with care and never push and drag with violence, in case that the footrests and tenons get loose or break.

家具的搬运及贮存(Carrying and store of furniture) 1、移动家具时，应搬掉柜内的物品，轻放轻移，切忌硬拖猛推，以免造成脚架和榫结构等松动或断裂。

QL have the same height as the chain after it connected, so the surface will be smooth. Beside, the heights of chutes are the same, the interval become smaller. The safety is higher than before. Moreover, we add the special tenons on the up and down each side, which can make the QL safer. Those special skills ensure the safety and won't be slipped under the normality.

QL 安全扣在组装后与链条为同等高度，故其小轴不会有凸出的问题，且因全部滑移面高度相同，故其间隙会变小，增加其安全性；另在 QL 安全扣的小径部两侧增设多重的卡掣块，形成多重保护，在正常使用的状态下无脱落的可能性，确保其使用上的安全性。

The work of this paper is as follows: 1. Looking back the progressing history of the linear motor, introducing the features of the elevator driven by linear induction motor, radicating the topic of this paper "the digital frequency variable control of the elevator bi-side direct driven by linear induction motor". The research of this paper covers the conventional VVVF control, space vector based VVVF control, vector control and DTC.
