Synthesis of Constructive-Functional Parameters to Improving the Dynamic Behavior of Automatic Mechanisms

Abstract:

Producing of mechanisms for automatic tool (ATCM), for machining centers requires higher performance, in terms of: the reduction of effective time for tool, simplification of kinematic chain, the increasing of reliability and operational safety, the reduction of weight of the entire subassembly, the increasing of positioning accuracy in handling tools. The paper presents how these desiderate can be achieved by improving the dynamic behavior. The objectives of the paper focused on the development of a methodology which allows judicious choice of functional-constructive parameter values, still from the design phase in order to achieve an optimization of the dynamic behavior of mechanisms for automatic tool change. The inclusion of dynamic model for the actuation (hydraulic) in full dynamic model has the advantage that it takes into account real parameters which are involved in the operation of these mechanisms. This paper develops a methodology that allows judicious choice of functional-constructive parameter values, still from the design stage. To obtain a version that is the closest to optimal functioning, in terms of dynamic analysis of the mechanism, the authors propose to develop a method of multi-criteria evaluation on dynamic characteristic parameters. This method ensures the choosing the closest to optimal functioning, in terms of dynamic analysis of mechanism.
