Embodiment Construction

[0020] The disclosed embodiments provide systems and methods for analyzing and testing multiple degrees of freedom objects. The system includes an interactive visual analysis and simulation (IVAS) tool for determining and / or validating (eg, validating) an operating envelope (eg, range of motion) of an object, such as a multi-degree-of-freedom object. An IVAS tool is a real-time interactive application that uses kinematic simulations (e.g., a video game engine), utilizing analysis tools (e.g., computer-aided engineering (CAE) data and / or product lifecycle management (PLM) data) to synthesize 3D product data (e.g., computer-aided design (CAD) models) to visualize complex systems and datasets. IVAS tools can model machine kinematics, component dynamics, and show integrated system operating sequences using data from traditional modeling and simulation applications.

[0021] IVAS tools can utilize a full or simplified representation of an object's 3D geometry exported from a CAD p...

Abstract

The application relates to a system and method for analyzing and testing multi-degree of freedom objects. The system includes a processor and a memory coupled to the processor. The memory stores instructions that cause the processor to determine a first motion envelope of an object. The first motion envelope corresponds to a kinematic envelope of positions of the object which are achievable. The instructions also cause the processor to determine an operational envelope of the object based on an intersection of the first motion envelope and a second motion envelope of the object. The second motion envelope corresponds to a range of motion of the object constrained by dynamic motion limits of the object, and the operational envelope is indicative of a range of motion of the object during operation of the object. The instructions further cause the processor to generate a virtual model of the object based on the operational envelope. The virtual model is used to virtually model operation of the object.

Description

technical field [0001] The present disclosure generally relates to systems and methods for analyzing and testing multiple degrees of freedom objects. Background technique [0002] Objects with multiple degrees of freedom are difficult to model virtually / analytically due to the millions or billions of potential positions. Such objects typically include hardware-based motion limiting devices, such as stops, restraints, bumps, sensors, etc., to limit the movement of the object so that the object does not experience a collision. Hardware-based motion restriction devices add weight, bulk, and design complexity. In addition, experiments are often performed on prototypes of the subjects to determine where the hardware-based motion restriction devices should be positioned. This adds time and cost to the design process. Contents of the invention [0003] In a particular implementation, a system includes a processor and a memory coupled to the processor. The memory stores instru...
