Abstract
The synthesis of systems to provide a required load motion is a demanding task. This paper presents a systems design approach to solving this problem. The design process has two distinct phases:(i) synthesis of a mechanism capable of performing the desired motion;(ii) synthesis of a hydraulic drive for the mechanism, compatible with the required motion.
Kinematic synthesis is performed by using the software package CAMFORD which can compare the motions of alterna tive mechanisms capable of performing a specified task. Required force- or torque-time relationships to drive the mechanism is also determined. A fluid power circuit capable of providing the required torque and motion characteristics is then designed using the BATHfp simulation package.
Design of a high-speed cutting machine illustrates integrated use of the two packages. The transient and steady-state response of the resulting system are presented. The advantages of using the systems approach in machine design are outlined.
