Lumped Parameter Modeling And Parameter Investigation Of An Electrohydraulic Crimping Hand Tool, Eric Norquist
Master's Theses (2009 -)
A lumped parameter model of a hand-held electrohydraulic tool was developed. The tool modeled was a Milwaukee Tool M18 12 Ton Crimper. First principle approaches were used to develop state-space models for each of the subsystems in the tool. The included subsystems were the tool motor and gear train, pump, return valve, and cylinder. The subsystem models were combined into a comprehensive eleventh-order nonlinear dynamic tool model. The tool model has two inputs and three outputs. The model inputs were the motor voltage and opening the return valve. The outputs were the motor current, application time, and retraction time. Each …
