Hello all, I have created a basic series and parallel rlc circuit in LTPSICE. According to this http://lpsa.swarthmore.edu/Analogs/ElectricalMechanicalAnalogs.html and https://www.tutorialspoint.com/control_systems/control_systems_electrical_analogies_mechanical.htm we can see that the output must be same if the values are interchanged. In the circuit I did I have used 1H inductor, 0.005F Capacitor, R=0.0002608 for the series rlc. For the parallel RLC we have to interchange L and C values and R=1/R as shown in the links. So R=1/0.0002608, C=1F and L=0.005H. But I am not able to get the proper output. Can somebody help me with it.

Thanks in advance

 

hi 12,
Consider the output impedance of the voltage source, try adding a low internal value, say 0.1R [Rser]

Hi

Add resistance (~100m) to the voltage source V1.
The period of the pulse generators should include Ton, Trise and Tfall times

Thank you @ericgibbs and @eetech00. it helped me a lot.
