There is an excellent book for this, Walter J. Karplus, Analog Simulation: Solution of Field Equations, 1958. Almost certainly out of print, but worth looking up.

Anyone know of any good designs for an easy-to-make analogue computer based on springs, masses, and dashpots?
That is, we want a supply of easily-interconnectable components that we can combine in ways that correspond to a prescribed differential equation, so that the behavior of the system will be a solution of the equation.
As I recall, there’s also a way to get hydraulic analogues of LRC networks (though I forget what the three sorts of components are called); is there a good design for a hydraulic computer?
