This paper describes the use of BIM models derived from point clouds for structural simulation based on Finite Element Analysis (FEA). Although BIM interoperability has reached a significant level of ...
The femur is the longest limb bone found in humans. Almost all the long limb bones found in terrestrial mammals, including the femur studied herein, have been observed to be loaded in bending and are ...
In a composite beam, transverse web stiffeners are often provided to the steel section at regular intervals along the beam span to eliminate local shear buckling as well as to reduce web distortion in...
Berms are used to control erosion and scouring by reducing the rate of surface runoff. In addition, the berms are expected to improve the stability of a slope. Regarding the standard for the gradient ...
A thermomechanical model of a shape memory alloy beam bending under tip force loading is implemented in finite element codes. The constitutive model is a one dimensional model which is based on free e...
In spite of ill-effects of high heel shoes, they are widely used for women. Hence, it is essential to understand the load transfer biomechanics in order to design better fit and comfortable shoes. In ...
针对线性非共振式振动干燥机工程上存在的问题,提出应用非线性振动理论,将其改进为非线性近共振双质体振动干燥机,简述了其工作原理,分析筛板可能承受系统突加载荷作用下的最大横向力,进行板簧曲面屈曲变形分析。研究表明:考虑物料粘度随温度而变化以及粒度不均匀性等因素而产生的突加载荷是正确的;板簧曲面由此发生屈曲变形而导致筒体的横向失稳是可能的。基于ANSYS软件建立了分析模型,解得板簧曲面各阶屈曲变形,可有...
The transient response of erodable surface thermocouples has been numerically assessed by using a two dimensional finite element analysis. Four types of base metal erodable surface thermocouples have ...
对某车用柴油机机体进行了三维实体建模和网格划分,采用有限元整体分析与子模型分析相结合技术,以ABAQUS为平台进行机体强度有限元分析,确定了气缸体应力集中部位,提出机体结构改进方案。在此基础上,应用MSC.Fatigue软件对改进前后的水套根部子模型进行疲劳强度分析,结合应力测试实验验证改进效果。实验结果表明,气缸体加筋改进后,水套根部交接位置应力降低11%~46%。
The most commonly used and cost effective method of transmission pipeline non destructive testing (NDT) utilizes the magnetic flux leakage (MFL) technique. The corrosion pits occur in many and comple...
根据生物质可压缩性以及成型物具有一定硬度等特点,将生物质成型过程看成非线性有限元问题。建立力学模型,利用ANSYS软件分析成型过程中的静水压应力、等效应变以及载荷与形变的关系,提出分段填料压缩可提高成型物的耐久性,采用缓慢压缩和提高物料的软化程度等方法可以防止成型物出现裂纹。
