Contact is of central importance in mechanics; it is also the key element in many applications of modelling and simulation technologies, and virtual environments. A particularly challenging problem is the simulation of the operation of large articulated mechanical systems that come to physical interaction with their environment. This usually induces contact simultaneously at many different locations in the system; while the bilateral constraints that model the articulations among the system elements also need to be maintained. Examples include the development of virtual environments for operations of large cranes moving cargo in an out of ships, excavators generally employed in the mining industry.

接触在力学中具有核心重要性;它也是建模和仿真技术以及虚拟环境的许多应用中的关键要素。一个特别具有挑战性的问题是模拟大型铰接机械系统的操作，这些系统与其环境进行物理交互。这通常会导致在系统中的许多不同位置同时接触;同时还需要保持对系统元素之间的关节进行建模的双边约束。例如，开发用于大型起重机在船上和船外移动货物的虚拟环境，以及采矿业中通常使用的挖掘机。
