finite element analysis of self destruction mechanism in a mechanical controller
نویسندگان
چکیده
in this study, dynamic behavior of a controller's self destruction mechanism has been simulated using 3d-fem in adams software and investigated. this paper has been concentrated on high acceleration controller's projectiles. this controller is mechanical and has been placed in top of the projectile. the goal of this study is to investigate the destruction mechanism operation i.e. movement of pin and balls to up and returning back. also, the time and angular velocity for beginning of these movements which are important in this mechanism are studied. finally, the simulated phenomena have been compared with available data qualitatively. this comparison confirms validity of the simulation.

Loading conditions and complex geometry have led the cylinder heads to become the most challenging parts of diesel engines. One of the most important durability problems in diesel engines is due to the cracks valves bridge area. The purpose of this study is a thermo-mechanical analysis of cylinder heads of diesel engines using a two-layer viscoplasticity model. In this article, mechanical prope...
متن کاملA Proposed Modeling Method in Finite Element Slope Stability Analysis
Limit-equilibrium method (LEM) and finite element method (FEM) with strength reduction method (SRM) techniques are the most widely used analysis tools in slope stability assessment. Recently, researchers have reported that both factor of safety (FOS) values and failure surfaces obtained from LEM and FEM are generally in good agreement, except in some particular cases. In this paper, the FOS and...
متن کاملStability Analysis of Salt Cavern Gas Storage Using 2D Thermo-Hydro-Mechanical Finite-Element Software
Ensuring the stability and integrity of underground gas storage salt caverns is a very complicated subject due to the non-linear and time-dependent behavior of rock salts under complicated thermal and mechanical loading conditions. For this reason, pressure and temperature fluctuations in the caverns and their surrounding strata must be integrated into the analysis and the numerical tools that ...
