Linear spring-dashpot model

NettetA dashpot, also known as a damper, is a mechanical device that resists motion via viscous friction. The resulting force is proportional to the velocity, but acts in the … NettetIn an ABAQUS/Standard analysis you can also model springs and dashpots that connect two points, acting in a fixed direction, or that connect points to ground. You define springs and dashpots using the Specialmenu in the Propertymodule or the Interactionmodule. Springs and dashpots created on a part are instanced along with the part.
