Active influence of joints in mechanical construction elements and structures e.g. for motor vehicle technology

摘要

The method involves targetted active influencing of joints by using the energy dissipation of contact surfaces in contact with each other under compression. One or more joint compression values are varied in a dynamically targetted manner using one or more physical effects. One or more joint compression values can be varied using one or more piezoelectric actuators (3). Alternatively, the magnetostrictive effect can be used. One or more construction elements of a shape memory alloy can be used to change one or more joint compression values by being subjected to predetermined temp. changes.
