The simulation of mechanical devices using multibody system dynamics (MBS) algorithms frequently requires the consideration of their interaction with components of a different physical nature, such as electronics, hydraulics, or thermodynamics. An increasingly popular way to perform this task is through co-simulation, that is, assigning a tailored formulation and solver to each subsystem in the application under study and then coupling their integration processes via the discrete-time exchange of coupling variables during runtime. Co-simulation makes it possible to deal with complex engineering applications in a modular and effective way. On the other hand, subsystem coupling can be carried out in a wide variety of ways, which brings about the need to select appropriate coupling schemes and simulation options to ensure that the numerical integration remains stable and accurate. In this work, the co-simulation of hydraulically actuated mechanical systems via noniterative, Jacobi-scheme co-simulation is addressed. The effect of selecting different co-simulation configuration options and parameters on the accuracy and stability of the numerical integration was assessed by means of representative numerical examples.

使用多体系统动力学（MBS）算法对机械设备进行仿真经常需要考虑它们与具有不同物理性质的组件（例如电子，液压或热力学）的相互作用。执行此任务的一种越来越流行的方式是通过协同仿真，即为正在研究的应用程序中的每个子系统分配量身定制的公式和求解器，然后通过运行时耦合变量的离散时间交换来耦合它们的集成过程。协同仿真使以模块化和有效的方式处理复杂的工程应用成为可能。另一方面，子系统耦合可以多种方式进行，这就需要选择合适的耦合方案和仿真选项，以确保数值积分保持稳定和准确。在这项工作中，解决了通过非迭代的Jacobi方案协同仿真对液压致动机械系统进行的协同仿真。通过代表性的数值示例，评估了选择不同的协同仿真配置选项和参数对数值积分的准确性和稳定性的影响。
