Torque converter fill dynamics with droop and primary influence - #20
Merged
Conversation
Add converter absorption slope λ(ν), separate drain/fill times, and speed governor droop to model realistic hydraulic transmission behavior: - Engine governor droop: set speed sags under load, follows converter demand - Circuit absorption λ(ν) = λ·(1 + slope·ν) models pump load variation with slip - Separate fill_time and drain_time: outgoing converter empties faster, creates the hole in tractive effort at the change point - Primary influence: shift point moves with notch (full power vs zero throttle) - steady_force() computes actual tractive effort curve from engine map and converter geometry — change point and all - suggest() derives starting parameters from five data sheet figures - Updated vehicle specs (BR 218, railcar) and comprehensive tests
