System ME3015 Dynamics (Woodruff School of Mechanical Engineering, Georgia Tech) ME3015 ASSIGNMENT #5 Read Chapter 7, Chapter 8, and Section 10-5 (I.1) The schematic given below shows a system for supplying fuel to automative engines using an electric fuel pump. An "accumulator", which consists of a piston (area A) moving with velocity v(t) under pressure p(t) against a spring (stiffness k) in the cylinder, is to smooth fluctuations in supply (volumetric) flow rate qs(t). You may assume that pressure drops are negligible except across the discharge orifice and that the linearized resistance to flow through the orifice is R. Answer the following questions: a) Show that the transfer function is given by Spring, k Pressure p Mass, m x(t) Pump qA(t) qs(t) Short pipe Orifice Flow to engine, q L (t ) . Fuel P( s) R(ms 2 + k ) = 2 . Qs ( s ) ms + A2 Rs + k b) Given m =1kg and A = 10cm2, determine k and R such that the system will have a damping ratio of 1 and a frequency natural of 10 rad/s. c) If the system experiences a step change in supply flow rate of 1cm3/s from its original steady-state operating condition, sketch the time response p(t) using the parameters determined in part (2). 2 2 n n P( s) = a 2 + bs 2 2 2 2 Qs ( s ) s + 2n s + n s + 2n s + n Hints: express the transfer function in the form. (I.2) The flapper-nozzle valve that consists of an orifice R and a variable flow resistance Rv (orifice with area A) shown below is used to position the mass m against a spring k. The volumetric flow rate through an orifice is pro...
