Truck Mounted Crane Analyzer

Many trucks are equipped with cranes for handling loads. Such cranes have a number of hydraulic cylinders that control the motion of the crane. These cylinders and other components that make up the crane are subjected to large forces when handling heavy loads. In order to determine the load-carrying capacity of the crane, these forces must be computed. In the Truck-Mounted Crane Analyzer app, a ...

Truck Mounted Crane

Many trucks are equipped with cranes for load handling. Such cranes have a number of hydraulic cylinders, controlling the motion, and several mechanisms. The cylinders and mechanisms that make up the crane are subjected to large forces when handling heavy loads. In order to determine the load carrying capacity, these forces must be computed. This model uses the Multibody Dynamics Module, ...

Slider Crank Mechanism

This is a benchmark model to test the numerical algorithms in the area of multibody dynamics. This model simulates the dynamic behavior of the slider crank mechanism. This mechanism goes through singular positions during its operation. The acceleration at a point is compared with the results from the reference.

Spring Loaded Centrifugal Governor

A centrifugal governor is used to control the speed of rotating machinery. One of the most common applications is in controlling the RPM of an engine by regulating the fuel supply. This model illustrates the functioning of a spring loaded centrifugal governor. The dynamics of the governor are analyzed under the influence of a centrifugal force, spring force, and damping force. The sleeve ...

Mechanics of a Golf Swing

How well you can strike a golf ball is not only determined by your muscle strength, but more importantly it is influenced by the mechanics of golf swing. The outcome of golf stroke is basically determined by the movement of the club head just prior to the impact with the ball. In this example, a multibody analysis of a golf swing is performed. Aim of the analysis is to maximize the club head ...

Dynamic Behavior of a Spring Loaded Rotating Slider

This model illustrates the modeling of slider motion caused by a base rotation. The motion of the slider is analyzed under various forces such as inertia force, centrifugal force, spring force and damping force. The prismatic joint, which is used to connect the two components, is spring loaded and also includes damping effects. The motion of the slider is compared with the analytical ...

Assembly with a Hinge Joint

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 parts can be either rigid or flexible or a combination as shown in this model.

Walking Instability in a Washing Machine

Walking instability, due to non-uniform distribution of clothes, is a common problem in lightweight portable washing machines. This problem is more severe in horizontal-axis washing machines, which are more popular because of their high efficiency in spite of high manufacturing cost. This model simulates a simplified model of a horizontal-axis portable washing machine and predicts the verge of ...

Centrifugal Governor Simulator

Centrifugal governors, a specific type of governor, control the speed of an engine by regulating the amount of admitted fuel. In order to maintain a near-constant speed, regardless of the load or fuel supply conditions, centrifugal governors use the principle of proportional control. While the governor is in operation, it is critical that it quickly reaches a new steady-state configuration. ...

Four-Bar Mechanism with Assembly Defect

This is a benchmark model for flexible multibody dynamics. This model simulates the dynamic behavior of a planar four-bar mechanism when one of the joints has a defect. The out-of-plane motion in the mechanism, caused by the defect in the joint, is compared with the results from the reference.
