rigid-body

基本解释

Bullet includes rigid-body simulation with both discrete and continuous collision detection, including support for soft bodies (such as cloth or other deformable objects).
Bullet 包括了具有离散和连续碰撞检测的刚体仿真，同时也支持软体（比如衣服或其他可变形物体）。
The model is comprised of the general rigid-body equations considering apparent mass and the modeling method of suspension system based on the assumption of "equilibrium points".
建立了这类系统的动力学模型，包括考虑附加质量的一般刚体动力学方程和基于“平衡点”假设的吊挂系统建模方法。
Gazebo models not only standard robot sensors (such as inertial measurement units, GPS receivers, and monocular cameras) but also real-world rigid-body physics for robotic environments.
Gazebo 不但可以对标准的机器人传感器（例如惯性度量单元、GPS 接收器和单筒相机）进行建模，而且还可以对机器人环境中使用的真实固形体物理部件进行建模。

The body design includes a rigid-mounted battery frame, which helps provide greater body rigidity compared to a conventional compact car.

刚体
The finite segment method is used for computing the elasticdeformation of an antiaircraft gun barrel. The dynamic model of the gun with 7-rigid-body and 18 degrees of freedom is established by means of Huston's method based on Kane's equations.
用有限段法计算高炮身管的弹性变形，用基于Kane方程的Huston方法建立了某高炮7刚体18自由度的多体系统动力学模型，对高炮发射过程进行了数值仿真，计算得出的炮口角位移明显大于不计身管变形的5刚体10自由度模型的计算结果。
