An integrated computational environment for computer-aided mechanical design will be developed and tested. The environment will support the key design tasks of function validation, dynamical simulation, parametric design, and functional tolerancing for a broad range of mechanical assemblies, such as camera shutter mechanisms, part feeders, robotic arms, and computer housings. The research will address the fundamental task of computing the effects of part contacts on function. Contact analysis is difficult and time-consuming even for experienced designers due to the quantity and complexity of the contact constraints in modern assemblies. The difficulty is greatest in assemblies with multiple contacts, meaning that different parts interact at various stages of the work cycle. There is no general purpose software for contact analysis. Contact analysis will be studied within the configuration space representation of mechanical function. Configuration space computation algorithms will be extended to the full range of planar assemblies and to selected spatial assemblies. Algorithmic support will be developed for the design tasks via configuration space manipulation. The software will emphasize breadth of coverage, depth of analysis, and robustness.

将开发和测试用于计算机辅助机械设计的综合计算环境。该环境将支持各种机械组件的功能验证、动态模拟、参数设计和功能公差等关键设计任务，例如相机快门机构、零件供给器、机械臂和计算机机箱。这项研究将解决计算部件接触对功能的影响的基本任务。由于现代装配中接触约束的数量和复杂性，即使对于有经验的设计人员来说，接触分析也是困难和耗时的。在具有多个触点的部件中难度最大，这意味着不同部件在工作周期的不同阶段相互作用。目前还没有用于接触分析的通用软件。接触分析将在机械功能的位形空间表示中进行研究。配置空间计算算法将扩展到所有平面组件和选定的空间组件。将通过配置空间操作为设计任务开发算法支持。该软件将强调覆盖面的广度、分析的深度和健壮性。
