This paper establishes an axisymmetric model for a levitation device. Therein, the Maxwell equations are combined with balance of linear momentum. Different possible formulations to describe MAXWELL presented and compared discussed in example. A high order finite element discretization using GALERKIN's method space generalized NEWMARK‐α time developed electro‐magneto‐mechanical approach. Severa...

Undoubtedly W. S. Rendra's poem “Nyanyian Dunia” can be brought closer to semantics, worldviews, and humanities values. However, the three things above become a contrast when faced with research that focuses on eroticism Newmark's method of translation. Mainly “Di Antara Kita” by Ajip Rosidi, which has not yet been analyzed. This study aims explain how erotic texts are presented create aestheti...

Hunting is a potentially dangerous phenomenon related to the lateral oscillation of wheels that impacts rails and causes wear infrastructure’s components. Therefore, analysis timely detection hunting can lead application corrective maintenance tasks, reducing damages, costs even derailments as result. In this work, vibration response finite element model rail with hunting-induced loads by singl...

In flexible manipulators, it is important the reduce end-effector vibrations. Suppression of vibrations significantly increases precision performed work. Selection velocity profile for giving motion to a manipulator crucial especially during high-speed motions. this study, effect 3rd order S-curve time parameters which related with natural period on endpoint beam are investigated. The results a...

Abstract The problem that impact dynamics caused by conductor breakage is not considered in the design of crossing frame appear at present. Therefore, system solution algorithm was established based on Absolute Nodal Coordinate Formulation (ANCF). Taking test free swing and drop as an example, correctness verified. results shown beam element used to establish dynamic equations which solved Newm...

This paper provides a finite element analysis of laminated composite plates under the action moving vehicle. The vehicle is modeled as rigid body with four suspension systems, each consisting spring-dashpot. Overall, possesses three degrees freedom: vertical, rolling, and pitching motions. equations motion plate are deduced based on first-order shear deformation theory. Using Euler-Lagrange equ...

In order to investigate the behaviour of worm drives, a new dynamic model, composed two blocks, is established and used extract numerical results. The tooth deflection drive, bearings, wheels inertias are taken into consideration. Newmark solving method applied solve motion equations. state contact teeth what enables these signals manifest themselves. Modal analysis developed different natural ...
