What is a compression only support Ansys?
What is a compression only support Ansys?
A Compression only support creates a frictionless contact with a rigid surface. That is like putting a pin in the hole. Bearing load creates a force on the nodes where the maximum force is at 0 degrees and zero force is at 90 degrees on either side and the distribution of force is sinusoidal.
What is compression only support in Ansys Workbench?
A “Compression Only” Support can be used to model flexible body to rigid ground contact. It uses frictionless contact and target regions. Because the “Compression Only” support uses Target & Contacts, Large Deflection behavior should be ON.
What is frictionless support in Ansys?
In ANSYS, Frictionless Support provide Support in normal direction to the selected face or edge. The body can not move or rotate or deform in normal direction. But free to move or rotate or rotate in tangential direction.
How are joints defined in Ansys?
Defining Joints in Ansys Mechanical. When using Ansys Mechanical most Joints are created between Remote Points. The underlying Joint element is a 2-noded (coincident) element and typically you want to connect 2 portions of the model that may have many nodes, eg the surface of a hole or edge.
What is cylindrical support in Ansys?
Cylindrical support is defined in cylindrical coordinates. In the below picture z is axial, y is tangential and x is radial direction. You can plot the undeformed and deformed shape to better understand how the object is constrained.
What is fixed support in Ansys?
July 2019 edited July 2019. All the descriptions below apply to solid elements, not shell elements. Fixed Support means X, Y and Z are all set to 0. If you have a plane of symmetry, that sets the displacement normal to that plane to 0.
What is elastic support in Ansys?
In case of ANSYS workbench, elastic support is used to act in a direction normal to selected faces on a body. It does not provide any stiffness that acts in a direction that is tangent to faces. Elastic support is modelled just selecting required face of the body and defining the respective foundation stiffness value.
What is bonded contact in Ansys?
Bonded. This is the default configuration and applies to all contact regions (surfaces, solids, lines, faces, edges). If contact regions are bonded, then no sliding or separation between faces or edges is allowed. Think of the region as glued.
What is remote point in Ansys Workbench?
Remote points are a way of abstracting a connection to a solid model, be it a vertex, edge, face, body, or node, to a point in space (specified by Location). Remote points allow you applying boundary conditions by defining points in the selected coordinate systems.
What is rough contact in Ansys?
Rough. Similar to the frictionless setting, these setting models perfectly rough frictional contact where there is no sliding. It only applies to regions of faces (for 3D solids) or edges (for 2D plates). By default, no automatic closing of gaps is performed.
What is roller support in Ansys?
It can be a roller or a hinge depending on which DOF you leave free. If all displacements are set to zero and two of the three rotations are set to zero, that will be a hinge around the one axis that had the rotation left Free. If one displacement is left Free, that is a roller.
What is elastic support?
An Elastic Support defines an elastic foundation between the selected faces of a part or assembly and the ground. This connector resists tension and compression.
How to do statistical structure analysis of helical compression spring?
The project work is based on design and 3D modeling of helical compression spring used in suspension system of vehicle. The statistical structure analysis would be done by Finite Element Analysis method in Ansys for different spring material and varying wire diameter of spring.
How to use a compression only support on a hole?
Is so, pick the cylindrical face of the hole and apply a compression only support. Don’t apply the force F on the right, that will be taken care of by the compression only support. Do apply the force on the left.
How can i compress the node numbers of a spring?
You can compress the node numbers by NUMCMP,NODE and element numbers NUMCMP,ELEM. Then, select the node of your body which should be connected to a spring.
How to analyze the statistical structure of a spring?
The statistical structure analysis would be done by Finite Element Analysis method in Ansys for different spring material and varying wire diameter of spring. Spring is to be design in Creo. The result would be compared and discussed to conclude the better one.
