Understanding the Different Elements of Gear Modeling

Pawan Soami | October 18, 2016

To accurately simulate a gear and obtain useful results, it is important to consider a number of elements behind the device’s design and how they are modeled. New features and functionality in the COMSOL Multiphysics® software provide you with the tools to address such properties and thus advance the reliability of your simulation studies. Today, we’ll review the various elements of gear modeling and explain how to account for them in our modeling processes.

Realistic gear geometries are useful for multibody dynamics simulations when coupled with other physical phenomena. Rather than manually building these geometries, we can use built-in parts available in the Part Library. With these highly parameterized gear parts, we can build a wide range of parallel and planetary gear trains and learn how to use different aspects of the built-in parts to create a realistic gear model in the Multibody Dynamics Module.

Gears are devices that are widely used for the transmission of rotary motion from one shaft to another. Automobiles, electric motors, wind turbines, and other machines all require a gearbox in order to change their speed or torque. With the latest version of COMSOL Multiphysics® — version 5.2a — we bring you new gear modeling features and functionality, from components in the Parts Library to an array of tutorial models that illustrate potential applications.

Shouldn’t the way you design a device be just as efficient as the device itself? When designing a centrifugal governor, the main goal is to increase the overall operation efficiency of an engine. With our Centrifugal Governor Simulator demo app, you can easily and quickly test a wide spectrum of parameters and physical studies to optimize the performance of the device. Today’s blog post offers insight.

Pole vaulting is one of the most difficult events to master in track and field. Athletes must be able to run fast, be strong enough to elevate their body by holding the pole, and have excellent body control in order to change position while airborne. Analyzing the science behind this sport offers greater insight into the mechanisms that ensure success.

Say you’re riding a bicycle and someone gives you a push from the side. To quickly stabilize yourself, you turn the handlebar of the bicycle in the same direction to counteract the fall. While riders do this instinctively, what’s fascinating is that our bicycles can do the same thing. Modern bicycles are designed to be self stable; they’re good at keeping balance while moving uncontrolled. Let’s take a look at how we can simulate this effect in COMSOL Multiphysics.

After recently encountering the equations of motion for rotating bodies for the first time, one of my sons came home with a number of interesting questions. His questions brought about a flashback, as I remembered sharing this sense of confusion when studying mechanics many years ago. In today’s blog post, I will present two COMSOL Multiphysics models — one of a gyroscope and one of a spinning top — that illustrate the remarkable properties of rotating bodies.

Truck-mounted cranes are designed to handle heavy loads. With this in mind, manufacturers and engineers look to optimize the machine’s payload, or carrying, capacity. Simulation apps can help expedite the optimization process by extending simulation capabilities into the hands of those who are not experts in simulation through a customized and intuitive interface. Our Truck Mounted Crane Analyzer demo app shows the benefits of this approach.

Lightweight and portable washing machines are great to use in situations where you do not have access to traditional washing machines. Yet problems may occur when a varied distribution of clothing causes walking instability in these machines. We tested for walking instability during the spin cycle of a portable washing machine and used an active balancing method in an attempt to remove this instability.

Truck-mounted cranes are often used for load handling. In many cases, this involves carrying heavy materials, which can exert large forces on various parts of the crane. See how simulation can help identify the impact of these forces and enhance the crane’s operation.
