In a gearbox, vibrations due to gear rattling and bearing misalignment are well known sources of noise. In this example, two shafts connected through a pair of gears are considered. The shafts are supported on roller bearings at their ends. Initially, the driven shaft is unloaded and the ... 詳細を見る

This model calculates the eigenfrequencies and mode shapes of an unconstrained cylinder in axisymmetry. The model is taken from NAFEMS Free Vibration Benchmarks. The eigenfrequencies are compared with the values given in the benchmark report. Three different physics interfaces are ... 詳細を見る

Bearings are used in machines to reduce the friction between moving parts and thereby smooth their relative motion. Rolling element bearings are one of the most widely used bearings, where rolling elements or rollers are used to support the load. These rollers can be of different shapes; ... 詳細を見る

In this tutorial the acoustic behavior of a duct or waveguide with a right angled bend is analyzed. The model uses port boundary conditions at the inlet and outlet. The ports can capture and treat non-plane propagating modes in waveguides, extending the analysis above the first cutoff ... 詳細を見る

This model shows how to use the scattered field formulation to compute the transmission coefficient for impinging P and S plane elastic waves onto a finite size phononic crystal. The transmission tends to zero in the frequency range corresponding to P- and S-wave band gaps, as ... 詳細を見る

In offshore applications, it is sometimes necessary to quickly seal a pipe as part of the prevention of a blowout. This example shows a simulation, in which a circular pipe is squeezed between two flat stiff indenters until it is almost flat. The model serves as an example of an analysis ... 詳細を見る

This example illustrates how to model a barrel hinge connecting two solid objects in an assembly. In this model, the details of the connection are not the focus of the analysis, therefore, the hinge joint is modeled using a Joint feature in the Multibody Dynamics Module. The connected ... 詳細を見る

In this example, the structural integrity of a cylinder made by a fiber composite is assessed both at the macroscale and at the microscale level. Along with macroscale analyses, structural composites need microscale stress and failure analyses to identify the critical constituents in ... 詳細を見る

Perforates are plates with a distribution of small perforations or holes. They are used in muffler systems, sound absorbing panels, and in many other places as liners, where it is important to control attenuation precisely. As the perforations become smaller and smaller, viscous and ... 詳細を見る

This example studies the deflection of a cantilever beam undergoing very large deflections. The beam is modeled using both the Solid Mechanics interface and the Beam interface. The results are compared with each other and with a benchmark solution from NAFEMS. In addition, a linear ... 詳細を見る
