PROJECT TITLE :

The Influence of Motion Paths and Assembly Sequences on the Stability of Assemblies

ABSTRACT:

In this paper, we have a tendency to gift an approach for the soundness analysis of mechanical half disassembly considering half motion in the presence of physical forces like gravity and friction. Our approach uses linear complementarity to investigate stability as components are removed of the assembly. As every part is aloof from the assembly along a specified path during disassembly, we have a tendency to compute the contact forces between elements within the remaining assembly; positive contact forces throughout the disassembly process imply the disassembly sequence is stable (since the parts remain in touch with each other). But, if the part that is being taken out induces motion of other elements within the remaining subassembly, we conclude the disassembly sequence is unstable. So, we tend to can simulate the entire disassembly considering physical forces and part motion, which has not previously been done. We then show the influence of part motion on stable disassembly. In distinction to previous work on disassembly that has centered either on coming up with part motions based mostly on only geometric constraints, or on analyzing the stability of an assembly without considering part motions, we tend to explore the relation between part motion and the choice of stable disassembly sequences in two-D and 3-D. We have a tendency to establish conditions that characterize path-dependent assemblies, where motion methods will play a significant role in stable disassembly. Since we track the motion of all components in an assembly, instability inducing motions can be identified and prevented by introducing appropriate fixtures by choosing various disassembly sequences or by changing the motion methods. We have a tendency to extend the steadiness analysis for single part disassembly to stability analysis of subassembly disassembly. We additionally show that in the presence of friction, assembly and disassembly can be noninvertible
