Improving the Operational Lifetime of a Reciprocating Engine
Reciprocating engines are used extensively for power generation in a variety of applications, most notably within the automobile industry. In the design process, it is important to ensure that all of the engine’s parts can withstand high stresses and loads in order to maximize the operational lifetime. Here, we analyze fatigue in an engine’s connecting rods.
The Motions and Mechanics of a Truck-Mounted Crane
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.
Simulating Vibration and Noise in a Washing Machine
The nonuniform distribution of clothes within a washing machine can produce notable vibration and noise. Modeling the dynamics behind this movement and sound can be a valuable tool in optimizing the design of these common household devices.
Biomechanical Model Evaluates Human Response to Vibrations
Depending on their magnitude and frequency, vibrations can be a source of discomfort and even pain for the human body. The impact of these vibrations is surely felt, but wouldn’t it be interesting to visualize how different parts of the human body respond when placed in such an environment? We introduce you to a multibody model that enables you to analyze the body’s dynamic response to vibrations.
Improving Your Golf Swing with a Multibody Analysis
How well you can strike a golf ball is not only determined by your muscle strength, but more importantly — it is influenced by several other factors involved in the mechanics of your golf swing. Let’s see how a multibody analysis of a golf swing can be used to improve the outcome of your stroke.
Selecting First Gear: Investigating a Classic Car Gearshift Mechanism
Cars come with either an automatic gearbox or a manually operated one, a stick shift. With a manual gearbox, we use the stick shifter very frequently while driving the car, yet we hardly ever think about the way the mechanism works. Here, we investigate how it works and what forces are acting on it when submitted to a very common load case — selecting first gear — with the help of a COMSOL Multibody Dynamics model of the gearshift mechanism.
Simulating an Engine Governor, the Spring Loaded Centrifugal Governor
We’ve probably all seen centrifugal force in action in one way or another, whether it be riding on a merry-go-round as a child, spinning a bucket of water upside and observing as the contents hug the insides of the bucket, or watching mud spinning off of a turning tire. In addition to making dizzying carnival rides, this force can be used in the design of many mechanical applications, where it is harnessed to control a variety of effects. One such […]
Aircraft Landing Gear Mechanism Analysis
Aircraft rely on landing gear in order to taxi, take off, and land. The landing gear of your average commercial airplane consists of a shock-absorber cylinder and piston, and a pair of tires. Intuitively, the shock-absorber experiences stresses as the landing gear touches the ground — but how much? In order to design a landing gear mechanism that can withstand many landings, and to determine when it’s time to swap out an old one, we can perform a multibody dynamics […]
