Part Mating Theory for Compliant Parts, Second Report, September 1, 1980-May 31, 1982

摘要

Theoretical models of compliantly supported rigid pegs entering compliant holes and minimum energy chamfers were used to analyze the mechanics of assembly. Key features of the 'peg-in-hole' model included large angle solutions and rotational hole compliance. The effect of various insertion parameters on the insertion force versus depth plot was determined. An experiment was carried out to verify experimentally the existence of minimum energy chamfers. Three aluminum chamfers were made and their insertion energies determined. One of the chamfers was an optimal slope chamfer and the other two were straight line chamfers. The straight line chamfers in theory had 18 percent more insertion energy than did the optimal slope chamfer. The experimental results supported the theory that chamfers flatter or steeper than the optimal slope chamfer have larger insertion energies.
