✦ Synopsis

The problem of determining the limiting performance of vibrating systems under shock loading is solved by replacing portions of the system by control forces which can represent any design. For the class of problems treated here, the performance index and the constraints are linear combinations of system response variables such as displacements, velocities and accelerations. Furthermore, the equations of motion are linear, so that it is possible to formulate the optimization procedure as a linear programming problem. In expressing the performance index and the constraints as linear functions of the unknown control forces, a modal approach is used to simplify and improve previous treatments of this problem. In spite of these linearity requirements, the control forces are not required to be linear functions of the response variab!es.

A pressure-limited hydraulic damper is proposed to achieve variable damping within a vibration isolation system. The variation in damping parameters is achieved passively by limiting the pressure differential across the damper piston, using pressure relief valves. The pressure-limited hydraulic damp

Quality assurance in design: Quality Ass

Quality assurance in design: Quality Assurance has been defined by the B.S.I. as ‘all those planned and systematic actions necessary to provide adequate confidence that a structure, system or component will perform satisfactorily in service’. This important topic will be of particular interest to those engaged in the chemical, process, petroleum, nuclear, power production and civil engineering industries. Quality Assurance in Design take the form of a collection of papers given by leading experts at the Joint IMechE/IChemE Symposium.
