Surfaces dynamically contact each other in many mechanical systems such as: meshing gears, ball bearings, loosely supported pipes and tubes (such as nuclear steam generators and fuel assemblies), and automotive brakes and belts/pulleys, where local intermittent contact can lead to fatigue and surface wear. A few other important applications of contact dynamics include: collision detection for remote teleoperation control and training software for robotic systems and remotely-operated vehicles, the dynamics of sports equipment, such as for golf and baseball, tires and even running shoes.

在许多机械系统中，表面动态地彼此接触，例如：啮合齿轮、滚珠轴承、松散支撑的管道和管子（例如核蒸汽发生器和燃料组件）以及汽车制动器和皮带/滑轮，其中局部间歇性接触可导致疲劳和表面磨损。接触动力学的其他一些重要应用包括：远程遥控操作控制的碰撞检测和机器人系统和远程操作车辆的培训软件，运动设备的动力学，如高尔夫和棒球，轮胎甚至跑鞋。
