In this series of studies, so far, transient response solutions have been investigated for various line systems. These analysis, however, were always made under one of the extreme conditions of the pipe-end such as closed-end or open-end. Under an extreme condition like this, the value of the wave reflection coefficient which is estimated for the pipe-end usually takes a real number 1 or -1, for example. On the other hand, the corresponding value for an actual line system, which is connected with a hydraulic-cylinder or motor, takes a complex number. Load systems of this kind, basically, can be modeled by a mass-spring system. In this paper, therefore, an analysis is made for a line system with a mass-spring load, and a transient response solution is derived by practicing inverse Laplace transformation in terms of Laplace transformation pairs. To show the validity of the solution, calculated results are compared with the ones obtained with a digital simulation method.
