Program for Analyzing Static Transmission Error of Helical Gears

The computer program HeliStat performs finite-element analysis to simulate meshing of helical gears. This program is a logical extension of the program DANST, which applies to spur gears. [DANST was described in "Computing Stresses in Spur Gears (LEW-15420), NASA Tech Briefs, Vol. 19, No. 12 (December 1995), page 73 and "Updated Program for Computing Stresses in Spur Gears (LEW-16575) NASA Tech Briefs, Vol. 22, No. 8 (August 1998), page 59.]
