Spatial 3-rod structure is one of the bus basic structures.Effects of the topological locations of angle brackets on the rigidity and strength of spatial 3-rod structure of bus body were discussed.The calculation by finite element calculation and experimental analysis showed that:1The structural rigidity and strength…
Stress triaxiality is a key factor in controlling the fracture of materials. Based on new method of finite element aided testing（ FAT）,the full-range constitutive relationship of ductile materials could be obtained. Thus,the distribution and evolution of stress triaxiality at the root of a funnel specimen is able to b…
Lightweight design on bridge crane exist the following problems by ANSYS: Mostly using static indicators as a design criterion,ignoring the dynamic performance; the whole process takes a long time; and the parameters optimized often should be rounded,weaken the effect. In this paper,taking the bridge crane with 20t- 2…
In order to study the influence of different metal materials on the strength of adhesively-bonded single lap joints（ SLJ）,The adhesive bonding of SLJs whose adherends were aluminum alloy,titanium alloy,copper alloy and cold rolled steel were separately tested under tension-shear loading in ANSYS software based on sing…
The kinematics of parallel structures in machine tool play an important role in the machining precision,and this paper focused on the kinematics and modeling of gantry parallel structure to analyze the dynamic response performance of the structure. It took a gantry parallel structure with plane motion for example,deco…
Maintain a high level of integrity and reliability of pipelines for oil and gas pipeline industry is essential. Due to various reasons,there will lead to the pipeline failure. Among them,pipeline defect is the main reason to the failure of itself.And dent defect is one of the general defect types. Therefore,it is nece…
The honeycomb core model was built by finite element method（ FEM）. And based on Hooke ’s law,the equivalent elastic modulus of honeycomb core influenced by the change of cell number was studied. The result indicates that the horizontal equivalent elastic modulus is affected slightly while the vertical equivalent elast…
The accidents of truck crane happen frequently during working because of the structure failure of hoist boom,which result in severe economic loss and casualties. So,the method combining probabilistic and non-probabilistic hybrid reliability theory with Bayesian Network is put forward to analyze the reliability of hois…
The damage of the aeronautical PMMA is mainly due to the fatigue cracking leaded by the residual stress.Residual stress will produce the orientated segment or group in the aeronautical PMMA which produce the birefringence effect. In this paper,based on the birefringence effect,the digital phase-shift photoelasticity i…
