H.5 – servohydraulic testing machines 00 series

Axial dynamic servo hydraulic testing machines series H. 5 series 00 in vertical design up to 500kN with servo cylinder in the foundation are designed to perform low and high cycle fatigue tests, fracture toughness, crack propagation, etc. This series of machines is characterized by high frame rigidity and mechanical resistance. The range of a given machine depends on the dynamic stroke and frequency. A specific test set is derived from these parameters, which consists of a test frame, a servo-hydraulic cylinder and a hydraulic unit.

Basic set of a dynamic testing machine

Focus on these 3 basic machine parts…

Machine frame – hydraulic servo cylinders – edge coaxiality corrections

Machine frame

First of all, consider what you want to try. Based on this consideration, select the machine frame – series 00 or series 01.

If you have a high frequency of adjustment of the working space, then complete the machine with an automatic electro-hydraulic transfer and clamping of the crossbar.

Hydraulic servo-cylinder

For the H.5 series 00, a maximum piston rod stroke height of 100 mm is recommended. It also depends on which HA you chose from the previous table and whether you use a classic dynamic sealing ring or a hydrostatic piston rod guide for higher lateral loads on the servo cylinder.

Coaxiality

Do you want to be sure? Use the BENTROD measuring and setting unit designed for evaluation and optimization of concetricity and edge coaxiality correction according to ASTM E1012, GES400 (NADCAP), GE450 and ISOTC 164SC5WG11

Selection of hydraulic unit including diagnostics

Hydraulic Unit (HU) selection 

HU is designed as a compact hydraulic pressure unit designed for fatigue tests with water or air cooling.

HU equipped with HALT 18 – Diagnostic SIEMENS control system with system monitoring of conditions, pressures and service intervals via touch LCD.

Noise

The possibility of covering HU is made by a special anti-noise cover PAC <72 dB. Easy access from all sides using quick couplings allows easy handling around the HU (filter change, oil change, etc.). Thanks to the silent block suspension, the HU can be placed directly on the test room floor.

Hydraulic connection

The connection between the HAD hydraulic unit and the machine frame is made using the VOSSFORM system, including the pressure test. Oil stains and gutters have no chance.

Appropriate selection of control unit and test software, including modules

Measuring and control electronics

EDCi Control electronics with synchronization of all measuring and control channels in real time with a sampling frequency of 10kHz.

Choose the RMCi7 or RMCi8 series remote control with OLED display integrated CENTRAL STOP.

Basic parameters of electronics

Analog signal resolution level ± 250,000 divisions (20 ms). Internal frequency 64 bit, data acquisition 32 bit, AD 24 bit, arithmetic, sampling frequency 10kHz. Integrated RS232 for VIDEO extensometers. PC connection – Ethernet 10/100 Mbit, USB 2.0.

Machine control and testing evaluation

BENTROD System

A solution that can precisely and easily set the coaxiality of a dynamic system

Zkušební zátěžové rámy řady H.5 firmy LABORTECH vykazují vynikající tuhost a souosost, což minimalizuje napětí v ohybu pro zvýšení přesnosti testu a snížení rozptylu dat. Správné vyrovnání zabraňuje mimoosovému namáhání ohybem, které může vzorek znehodnotit (pořízení a výroba vzorku je velmi nákladné) nebo výsledná data budou zkreslená a tudíž nepoužitelná. Měřící a nastavovací jednotka BENTROD určená pro vyhodnocení a optimalizace soustředné i hranové korekce souososti (nesrovnanosti) upínacích čelistí pro statické a dynamické zkušební stroje dle normy ASTM E1012, GES400 (NADCAP), GE450 a ISOTC 164SC5WG11
