Can damping coefficient be negative
WebSep 29, 2024 · There is no one definitive answer to this question. However, some methods that could be used to calculate the damping ratio include:1. Calculating the natural damping factor (NDF) of the system. This is the ratio of the system’s damping capacity (C) to its natural frequency (F).2. Calculating the effective damping capacity (EDC) of the … WebNov 16, 2024 · In fact, that is the point of critical damping.
