摘要

Arrangement introduced in test equipment of mechanical resistance to fatigue of materials used in the construction of the combustu00ecvel tank cars.Understand this patent of utility model an improved test equipment of mechanical resistance to fatigue of materials used in the construction of the fuel tank, through the process of vertical vibration with pulsating pressure positive and negative pressure pulsating Containing a vibrating table (1) formed by a basic structure (LA) with a head (1b).Supported on sliding supports (1c), which is fixed a special structure (1D), supported on rubber dampers (2) which is fixed to the tank (3) in its upper part, to simulate its attachment on the chassis of the vehicle.Containing, rubber feet (vibrates stop) (4), electro hydraulic actuator (5), the hydraulic cylinders are coupled in the lower part of the table top to produce a movement of the vertical cyclic vibration and a control panel (6), the type console is connected to the mobile tanq The EU by a hose of an air supply (7), which controls and monitors the whole test.Being composed of a processing unit (PLC) with source and banks of memory. Also containing an accelerometer (11), which is connected to an interface module (12) and a computer (13), with soft dedicated, which controls a set of hydraulic pumps (14), with the electric panel (15) and (16), the cooler the water feeder of hydraulic cylinders of the electro hydraulic actuator.The control of positive and negative pressure through the processing unit (PLC), man machine interface (MMI), air treatment unit (AWU), pressure sensor (SP), a pressure regulator (PR), precision (VPP) proportional valve, directional valve (RV) generator. V u00e1cuo (GV) and blocking valve (VB)
