Truck Mounted Crane Analyzer
Application ID: 22291
This app demonstrates the following:
- Using the knob form object
- Updating the geometry by rotating a knob
- Provides info if the results are above or below certain critical values
Many trucks are equipped with cranes for handling loads and 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 app, a rigid-body analysis of a crane is performed in order to find the payload capacity for the specified orientation and extension of the crane.
Inputs include the angle between the booms, the total extension length, the capacity of the inner and outer boom cylinders, and the capacity extension cylinders. Results from the app include the payload capacity and hydraulic cylinder usage.
This application example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
