Optimization design of tower crane steel structure is very important for design technique development of tower crane. This paper proposes a kind of parametric optimization model based on Ansys OPT, combined with finite element analysis (FEA) and overall stability theory. The tower body is taken as an example to introduce the building process and the program structure of the parametric optimization...
In this paper, by using the finite element analysis software-ANSYS and the direct coupling method, the stress of platinum-carbon (Pt-C) high temperature fixed-point crucible during phase transition process was analyzed. The stress profile of the crucible was identified through the stress diagram analysis. From analyzing the stress diagram, we recommend a novel optimal hybrid crucible structure. Again...
Base on actual project and consider geometric nonlinearity and material nonlinearity of structure, the numeric model of long-span continuous rigid frame bridge with high piers is built by using the current FEM software ANSYS. On the basis of the study of sensors optimization placement for bridge, real-time monitoring to different construction stages and work environment of long-span continuous rigid...
The leaf spring is the flexible component of dependent suspension, which has advantages of simple structure, convenient maintenance, low cost, and can be used to locate the axle. The traditional multi-leaf spring has various defects. The few-leaf-spring has been one of main development trend of leaf springs because of its excellent characteristics. In this paper, a few-leaf-spring with variable thickness...
In this paper the principle of magnetic fluid seals is discussed. Based on the finite element software ANSYS, the magnetic field of magnetic fluid sealing device with three slots and four pole teeth is analyzed, and the size parameters of magnetic fluid sealing pole are optimized. The results show that the difference between the maximum and minimum intensity of magnetic field in the area near the...
In this paper, we report the design, simulation and optimization of a novel polymeric out-of-plane electro-thermal micro-actuator. The electro-thermal micro-actuator consists of tri-layers: the passive Ni layer, an expanding SU-8 layer and a curling S-shaped Ni heater. The tri-layer actuator is accompanied with a suspended structure to produce an out-of-plane movement perpendicular to the substrate,...

Proceed from analysis results of finite element, has formed the mathematics model of optimization design, put forward the comparatively rational light design plan of quantization of pairs of...
Sensitivity analysis and optimization based on the combination of Pro/MECHANICA and ANSYS are applied to designing of the connecting rod of LJ276M electronic gasoline engine. The maximum stress of connecting rod on the largest compression condition is reduced by 4.9% after the optimization is applied, static intension safety coefficient is increased by 5.4% and mass of connecting rod is also reduced.
A parametric platform for the drum brake automatic modelling and nonlinear analysis is established with the parametric programming language (APDL) and user interface design language (UIDL) in ANSYS. The platform is easy to use and flexible, requiring user only to input different parameters in the dialog boxes, then geometric model can be created automatically by assigning values to parameters, and...
An array of accelerated temperature cycling (ATC) finite element (FE) simulations using ANSYStrade, and drop-impact finite element simulations using LS DYNAtrade, are used to find the optimum elastic modulus and coefficient of thermal expansion (CTE) for a stacked chip scale package. For the ATC simulations, Anand's constitutive model with properties for Sn96.5Ag3.0Cu0.5 (SAC305) and tin-lead eutectic...
This paper realized structural analysis of rotating hook-lift garbage truck based on ADAMS/ANSYS. Firstly, software ADAMS was used to realize dynamic simulation of working process. In order to get curves of dynamic parameters of each component simultaneously, it took external loads and equilibrium of reaction forces of each part as checking conditions. Secondly, this research took the information...
A cross-shaped torsion mirror, fabricated by a micro-machining process, was analyzed by finite element analysis with ANSYS and COMSOL software packages. The micro-structure's resonance frequencies and mode shapes were also measured by using the Electronic Speckle Pattern Interferometry and Stroboscopic Interferometry techniques, which both are full-field and non-contact experimental procedures. Four...
A method for obtaining the array manifold in sensor array beampattern optimization is proposed in this paper. The proposed method is based on sound field prediction, using software packages ANSYS and SYSNOISE to simulate the process of measuring the array manifold in practical systems. For a given array supporting structure, the numerical boundary element method is used to calculate the array outputs...
