In january 1996 , the school of mechanical engineering was established , which included the department of precision instruments and echanology , the department of mechanical engineering , and the department of automobile engineering 1996年1月，由精密仪器与机械学系机械工程系和汽车工程系组成机械工程学院。 1998年10月，为了促进多学科的交叉和综合，热能工程系和工程力学系进入机械工程学院。
Tensegrity as a new structural conception has many connections with inter - discipline since it was proposed . fuller ' s synergetic philosophic idea , form finding , morph categorization and mechanics properties have a great contribution to the application of the essence of the human thinking Fuller协同的哲学思想，几何形态的寻找，归类以及工程力学性质分析都为张拉整体这一人类思想的精髓应用于实践工程中做出了很大的贡献。
Besides this , the thesis start with the conjunct point of mechanic engineering and soil mechanics . consider the equipment and action medium - soil as a whole body . study the dynamic performance of interaction between the compaction equipment and soil 此外，本文还从机械工程和土体工程力学两学科的结合点入手，把施工机械与被作业对象? ?土壤作为一个完整的系统，进行压实装置与土壤相互作用动态特性的研究，建立了系统的动力学模型。
The results in this paper indicate that the two boundary conditions , permeable boundary condition and sealed boundary condition , of surface , permeability of the media , and surmounting loads of surface , all have influence on the dynamic response of two - phase media to a certain extent 中国地展局工程力学研究所硕士学位论文曰. . ‘ . . . . . . . . . .研究表明表面透水条件、介质渗透性、上覆荷载等因素对两相介质的动力响应都有一定的影响。
Our strength is in the fact that based on the national standard and architectural aesthetics , the most suitably custom - made project is delivered to our customers by utilizing our professional understandings on human engineering , aesthetics , mechanics of materials and the material science , engineering mechanics , industrial design science , and graphics design 详细说明我们能够从建筑学和美学的角度，综合建筑特色，企业文化，地域文化，行业特征等因素，运用人机工程学，美学，材料学，工程力学，产品设计学，平面设计等专业知识，结合相应国家标准，为客户量身定制出最适合的产品。
The notable torsion effects of the surface ground motion above the alluvial valley are illustrated and the torsion effects become stronger as the frequency of the incidence is higher . ( 4 ) antiplane surface motion of the underground circular soft inclusion and the underground homogeneous soft interlayer is investigated in this paper . the results indicate : surface displacement amplitudes just above the soft inclusion of small depth - to - width ratio is amplified and soft interlayer of small depth - to - thickness ratio is amplified to a certain degree , and moreover , the latter is lower limit of the former 结果表明：垂直入射时，小深宽比软夹塞上方地表位移幅值有较大的放大，小深厚比软夹层的地表位移幅值也有一定的放大，且后者为前者的下限；波接近掠入射时，软夹塞正上方地表点和软夹层的中国地震局工程力学研究所硕士学位论文一地表位移幅值都没有放大，而软夹塞迎波面一侧地表点的位移幅值会有一定的放大；软夹塞上方的地表位移运动有较强烈的扭转效应，且此扭转效应随入射波频率的增高而增强。
Reviewing and summarizing the existence theory for maintenance time decision , their shortcomings are analyzed , in which the economic factor is considered more than the safety factor . so in this paper from the point of security and risk cost the natural usage limit state reliability index is put forward as the maintenance time decision rule . the right bank section of danjiangkou dam of the south - north water transfer project ( snwtp ) as an example is analyzed to decision the maintenance time 另外，回顾现有结构维护时间决策的准则问题，一般是偏向于从工程经济角度考虑问题，而对结构使用的安全性考虑的较少，针对上述决策准则的不足之处，本文从工程力学的角度出发，综合考虑了结构的安全性和风险，提出了以正常使用极限状态的可靠指标作为维护时间的决策准则，并以南水北调工程丹江口水利枢纽的右联混凝土坝为例进行了维护时间的决策分析。
