![]() Alter the density and Young's modulus of the concrete and see how this critical frequency changes. Conduct a harmonic analysis and find out what frequency induces resonance in the beam. Homework Example of a beam under lateral excitationĪssume a piece of vibrating equipment sits in the middle of a simply supported concrete beam and is providing a cyclic force. Follow along with the provided How To Video file. Download the zip file and extract the contents. Modal analysis of the washing machine frame will show you these frequencies and mode shapes. The uneven distribution of mass causes the machine to resonate at the rotating frequency. You might notice that your washing machine sometimes vibrates drastically. Take a look at this simulation and find out how a harmonic analysis is done on this suspension assembly. Running a harmonic analysis on the car suspension assembly is the first step in understanding its behavior. Why is this car moving steadily on such a bumpy road? The credit goes to the design of the car's suspension assembly. (3) Harmonic analysis of an automotive suspension assembly rotation speed relationship? Check out this simulation and find out. Assuming there is an uneven distribution of mass, what would be the expected force vs. A small misalignment or uneven mass distribution could result in a high reaction force to the connected equipment. (2) Equipment vibrating due to misalignmentĪccuracy is crucial in high-speed rotating equipment. What could be a dangerous vibration frequency for the electronics in a closed cabinet? You are encouraged to run the simulation and find out. When designing electronic equipment, it is important to consider possible vibration of the nearby environment. Download the student version of Ansys software here. All of the simulations are conducted using Ansys Mechanical. Each of them comes with a description file, video instruction, and Ansys simulation file. Several simulation examples are provided here.
