class Ifc4x1::IfcVibrationIsolator : public Ifc4x1::IfcElementComponent

A vibration isolator is a device used to minimize the effects of vibration transmissibility in a building.

HISTORY New entity in IFC2x4

Type Use Definition IfcVibrationIsolator defines the occurrence of any vibration isolator; common information about vibration isolator types is handled by IfcVibrationIsolatorType. The IfcVibrationIsolatorType (if present) may establish the common type name, usage (predefined type), properties, materials, composition, assignments, and representations. The IfcVibrationIsolatorType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcVibrationIsolatorType has aggregated elements, such objects are reflected at the IfcVibrationIsolator occurrence using the IfcRelDefinesByObject relationship.

Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcVibrationIsolatorType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcVibrationIsolatorType.HasPropertySets. If both are given, then the properties directly defined at IfcVibrationIsolator override the properties defined at IfcVibrationIsolatorType. Refer to the documentation at the supertype IfcElementComponent and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_VibrationIsolatorTypeCommon (PSET_TYPEDRIVENOVERRIDE)

Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.


Material Use Definition The material of the IfcVibrationIsolator is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcVibrationIsolatorType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:

Body: The primary material from which the object is constructed. Damping: Material from which the damping element of the vibration isolator is constructed.
