| Abstract (English): | Multi-body dynamic simulation involving rigid bodies and constraints plays a critical role in physical simulation and has widespread applications in engineering analysis, virtual reality, and game animation. Traditional rigid-body physics engines primarily rely on CPUs for computation. However, in modern computer graphics and real-time physics simulation, the parallel computing power of GPUs has been demonstrated to significantly enhance performance. This study explored the implementation of five Jacobian-based constraint solvers on the GPU and analyzed their performance and stability. These solvers included the projected Jacobi (PJ) solver, the combined projected Jacobi and nonlinear Jacobi (PJNJ) solver, the projected Jacobi with soft constraints (PJSoft) solver, the substep-based Jacobi (TJ) solver, and the substep-based Jacobi with soft constraints (TJSoft) solver. Benchmark tests revealed that the soft-constraint method provided smoother constraint impulse responses, while employing a substep strategy results in more stable solutions, particularly for high mass ratios and complex scenarios. Overall, this work offered a fresh perspective on evaluating GPU-based constraint solver strategies in multi-body simulations and served as an important reference for real-time physics simulation and interactive computer graphics.

| Abstract (Chinese): | 包含刚体和约束的多体动力学模拟在物理仿真中占有重要地位, 广泛应用于工程分析、虚 拟现实以及游戏动画等领域。传统的刚体物理引擎主要依赖于 CPU 进行计算, 而在现代计算机图形学和 实时物理模拟中, GPU 的并行计算能力被证明能够显著提高计算性能。为此, 研究探索了 5 种基于雅可比 方法的约束求解器在 GPU 上的实现并对其进行了性能与稳定性分析。具体包括：投影雅可比求解器 (PJ) 、 结合投影雅可比与非线性雅可比的求解器 (PJNJ) 、投影雅可比与软约束求解器 (PJSoft) 、基于子步骤策略的雅 可比求解器 (TJ) 和结合子步骤策略的雅可比与软约束求解器 (TJSoft) 。在基准测试中, 软约束方法展现出平滑 的约束冲量响应, 且子步骤策略在处理高质量比和复杂场景时提供了更为稳定的解决方案。本研究为评估多 体模拟中基于 GPU 的约束求解方案提供了新的视角, 对实时物理模拟和交互式计算机图形学具有重要参考 价值。 [ABSTRACT FROM AUTHOR] |
