| Description |
The problem of providing the required work resource of hydraulic membrane mechanisms, which are used for precise small displacements under load in mechatronic systems of rolling mills and oscillation mechanisms are considered. The most loaded and deformed element of the hydraulic membrane mechanism, which determines its work resource is steel membrane. The analysis of the numerical simulation results of the steel membrane`s stress-strain state at various values of its geometric parameters was carried out. On the basis of the obtained results analysis the engineering technic of rational geometrical parameters choice of the hydraulic membrane mechanism`s steel membrane is proposed. According to the proposed engineering technic, the conditions of the hydraulic membrane mechanism`s work and its characteristics (load, operating speed, oscillation frequency and etc.) must be determined primary; the desired resource must be given. At the next stage, taking into consideration the operational experience, the geometric parameters of the membrane, which significantly affect its stress-strain state, material of the membrane and its work resource have to be chosen. At the stage of mathematical modeling preparation, boundary and initial conditions, numerical method and software for calculation should be selected. After simulation, an analysis of the obtained results according to the maximum stress and relative deformation should be performed. For combinations of geometric parameters values which satisfy the requirements of the work resource, an approximation must be carried out by the chosen method to obtain the dependence of the membranes maximum stress and its geometric parameters. At the final stage of calculation, during the choice of the membrane`s rational geometric parameters it is also necessary to consider the design and technological constraints (the presence of the required membrane material sheet metal gauge, the connecting and overall dimensions of the hydraulic membrane mechanism).The proposed engineering technic of rational geometrical parameters choice of the hydraulic membrane mechanism`s steel membrane of mechatronic systems provides high-precision displacement under load and takes into account the stress-strain state of the hydraulic membrane mechanism and its work resource.
