To reduce vibration and noise, a damping layer and constraint layer are usually pasted on the inner surface of a gearbox thin shell, and their thicknesses are the main parameters in the vibration and noise reduction design. The normal acceleration of the point on the gearbox surface is the main index that can reflect the vibration and noise of that point, and the normal accelerations of different points can reflect the degree of the vibration and noise of the whole structure. The K-S function is adopted to process many points’ normal accelerations as the comprehensive index of the vibration characteristics of the whole structure, and the vibration acceleration level is adopted to measure the degree of the vibration and noise. Secondary development of the Abaqus preprocess and postprocess on the basis of the Python scripting programming automatically modifies the model parameters, submits the job, and restarts the analysis totally, which avoids the tedious work of returning to the Abaqus/CAE for modifying and resubmitting and improves the speed of the preprocess and postprocess and the computational efficiency.

Similitude design for the vibration problems of plates and shells: A review
Yunpeng ZHU, You WANG, Zhong LUO, Qingkai HAN, Deyou WANG

Similitude design plays a vital role in the analysis of vibration and shock problems encountered in large engineering equipment. Similitude design, including dimensional analysis and governing equation method, is founded on the dynamic similitude theory. This study reviews the application of similitude design methods in engineering practice and summarizes the major achievements of the dynamic similitude theory in structural vibration and shock problems in different fields, including marine structures, civil engineering structures, and large power equipment. This study also reviews the dynamic similitude design methods for thin-walled and composite material plates and shells, including the most recent work published by the authors. Structure sensitivity analysis is used to evaluate the scaling factors to attain accurate distorted scaling laws. Finally, this study discusses the existing problems and the potential of the dynamic similitude theory for the analysis of vibration and shock problems of structures.

南京长江第四大桥南锚碇基础为支护开挖深埋扩大基础,采用井筒式地下连续墙支护体系,平面形状为“∞”形,长82 m,宽59 m,由两个外径59 m的非完整圆和一道隔墙组成,壁厚为1.5 m。隔墙为前后两个非完整圆的支撑结构,抬高隔墙底标高,使得基础底板为一整体结构;填心混凝土施工完成后凿除部分墙体,既解决了开挖状态下的支护问题,又使基础顶板有效连为整体。采用“∞”形比圆形或矩形结构形式布置平面面积小,截面惯性矩大,且半径较小,墙体环向应力小,安全性及可实施性高,有效降低了工程投入,提高了结构的安全性。
