afinite element model is developed for simulation of the curing process of a thick axisymmetric rubber article reinforced by metal plates during the molding and cooling stages. the model consists of the heat transfer equation and a newly developed kinetics model for the determination of the state of cure in the rubber. the latter is based on the modification of the well-known kamal-sourour mode...

The need for simulation of human foot mechanism has made researchers and engineers move towards different patterns to describe this movement. In this regard, optimal solutions such as energy consumption, accuracy, etc. are of utmost importance. In this paper, efforts have been made to present a new solution by designing a fully two-dimensional six-bar mechanism with one degree of freedom so tha...

Introduction:  Pressure  sores  refer  to  lesions  that  are  produced  while  a  constant  pressure  causes  necrotic  tissue to grow. The need for a better comprehension of the process has led researchers to artificial generation  of  pressure  sores.  Modeling  the  mechanical  behavior  of tissue  will  provide  a better understanding  of this  process as well as a more suitable selection ...

In this paper, the experimental vibration analysis of a single cylinder air compressor based on a hypocycloid straight line mechanism (HSM) is investigated. The HSM mechanism uses planetary gears to convert rotational motion to purely linear motion. In the conventional air compressor, the slider- crank mechanism is replaced by the HSM mechanism with appropriate counterweights. The constructed s...

Protective Reinforced Concrete (RC) barrier walls of nuclear or industrial facilities are required to withstand accidental intentional missile impact. The missiles (projectiles) can be classified as hard, semi-hard soft. In particular, an airplane crash on a reinforced concrete structure causes local and global damage the structure. Local mechanisms usually associated with impact hard aircraft ...

In this paper, the dam of Baihetan Hydropower Station was taken as an example to establish a refined three-dimensional finite element model (FEM) dam-dam foundation based on comprehensive analysis safety monitoring data during whole life cycle and simulation for process dam, so accurately understand working behavior impounding process, do feedback influence mechanism overall deformation arch in...

It is well known that sliding mode control algorithm can give good transient performance and system robustness. However, due to the sensitivity of the sliding mode controller before reaching the sliding surface and the presence of chattering may introduce problems to motion tracking control of robot manipulators. In this paper, a proposed technique to adaptively tune the sliding mode controller...

Affected by electric field generated in power transmission line, live worker on the high-voltage line is dangerous working environment. In this paper, posture perception, numerical simulation, and risk assessment are adopted to realize deep fusion of physical trajectory spatial virtual distribution worker, digital twin bodies different scenarios constructed. Firstly, trajectories 3D model livin...
