多体动力学用于交互式和实时应用，从电脑游戏到虚拟原型和工程。所有这些领域都在努力实现更快、更大规模的模拟。特别具有挑战性的是具有高度组织和结构化堆叠的大规模模拟。我们提出了一种稳定的、鲁棒的、通用的多体动力学仿真方法。新颖的贡献包括一个新的、明确的、固定的时间步进方案，用于基于速度的互补公式，使用激波传播和一个简单可靠的实现策略，用于专门针对多体动力学优化的迭代互补问题求解器。
Multibody dynamics are used in interactive and real-time applications, ranging from computer games to virtual prototyping, and engineering. All these areas strive towards faster and larger scale simulations. Particularly challenging are large-scale simulations with highly organized and structured stacking. We present a stable, robust, and versatile method for multibody dynamics simulation. Novel contributions include a new, explicit, fixed time-stepping scheme for velocity-based complementarity formulations using shock propagation with a simple reliable implementation strategy for an iterative complementarity problem solver specifically optimized for multibody dynamics.
