This proposal is a continuation of the previous successful collaboration with CMLabs Simulations. It builds on the results achieved in the previous projects of this collaboration. We will continue and expand the work to investigate some of the important, challenging problems in dynamics modelling and simulation of large-scale mechanical systems such as construction machinery, cranes and port equipment, robotic workcells and operations. In our work we will specifically focus on the further development and implementation of a general formulation of mechanical system models. In this framework the system elements can be connected to each other through bilateral and unilateral interactions that are representable by constraints or constitutive relations. We will develop and implement mathematical models, techniques, and algorithms that are made possible by this formulation. We will also investigate the feasibility and performance of numerical solution algorithms asthey pertain to the different model forms. In the project we plan to train a group of 16 HQP trainees. The proposed work will be structured into three groups of activities that have several interconnection points.\ We expect that the results of the work will produce important research findings that will strongly contribute to the Canadian economy. The simulations and virtual environments industry has strong roots in Quebec. The expected results will further strengthen this industrial sector, and will generate the basis for new business opportunities and contribute to the creation of new jobs. This will be of significant benefit to our partner, CMLabs Simulations Inc., and the Canadian society at large.

该提案是之前与CMLabs Simulations成功合作的延续。它建立在这一合作的前几个项目所取得的成果的基础上。我们将继续并扩大工作，以研究大型机械系统（如建筑机械，起重机和港口设备，机器人工作单元和操作）的动力学建模和仿真中的一些重要的，具有挑战性的问题。在我们的工作中，我们将特别关注进一步开发和实施机械系统模型的一般公式。在这个框架中，系统元素可以通过双边和单边的相互作用相互连接，这些相互作用可以通过约束或构成关系来表示。我们将开发和实施数学模型，技术和算法，这是可能的制定。我们也将探讨数值解算法的可行性和性能，因为它们属于不同的模型形式。在该项目中，我们计划培训一组16名HQP学员。拟议的工作将分为三组活动，它们有几个相互联系的点。我们希望这项工作的结果将产生重要的研究成果，这将大大有助于加拿大经济。模拟和虚拟环境行业在魁北克有着深厚的根基。预期成果将进一步加强这一工业部门，并将为新的商业机会奠定基础，有助于创造新的就业机会。这将对我们的合作伙伴CMLabs Simulations Inc.产生重大影响，以及整个加拿大社会。
