Fatigue Testers Ensure The Reliability Of Your Springs
|
|
Your springs are highly stressed, critical components. Your customers demand a long working life and high performance. To be completely certain that your springs achieve the highest standards of reliability and performance, the experts at IST - the unique centre for research and development of spring technology - recommend fatigue testing of sample spring batches.
IST is a long-standing supplier of high quality fatigue testing machines which have a proven track record both in industry and in our own extensively used test laboratories.
|
Our standard range of machines are designed to be easy to set up and use, and are built to give many years of excellent service. All of the machines have variable speed facilities, from 10% to full-scale to enable accurate simulation of service conditions.

Fatigue Testers - Standard Features Include:
- Infinitely variable stroke for accurate testing of all spring designs.
- Automatic cycle counting for continuous display of cycles achieved.
- Test station fully guarded.
- Pre-set test duration to allow weekend and holiday period testing.
- Failure detection and automatic shut-down to allow 24 hour unattended running.
|
- Force feed oil lubrication to all critical moving parts for reliable, continuous operation.
- Variable test speed with speed read-out for reliable simulation of service operation.

Standard Options
When you invest in an IST fatigue tester you are not just limited to standard models. If you have a special need we can incorporate your specifications into any of our standard machines. The following are examples of the types of work we can carry out:
- Special jigging for spring types / assemblies.
- Environmental test chamber, e.g. temperature or corrosion.
- Load cell failure detection to trip failure on loss of spring load.
- Increased testing envelope (spring length / diameter).
|
- Increased test stations on single station machines.
- Special machine for spring types, e.g. anti-roll bar machine.
- Other supply voltages available.

VALVE SPRING FATIGUE TESTING MACHINE TYPE FT6 HO
12 Station Valve Spring Fatigue Tester

Twin Test Head & Oil Sprays
|
The machine is a radial type, twelve station, machine with a removable twin head system to enable single larger springs to be tested. The actuating mechanism enables the machine stroke to be infinitely adjusted from 0.5 to 30mm.
The fixed spring ends are supported on a double crosshead using a single preload screw mechanism. The springs are preloaded by means of a hand wheel and locked into place using a locking wheel.
All bearings are force lubricated by a separate motorised oil pump. The lubrication system incorporates filter, cooler and low oil pressure cut-off.
The machine drive is via a variable speed drive enabling test speeds at up to 40Hz (2400 r.p.m.).
The machines control system is enclosed in a freestanding console. The HMI displays individual cycle counters (24 in total) for each testing station and monitors the cycles to failure. A master pre-setable counter is fitted to enable the number of test cycles to be pre-programmed.
The failure detection system monitors each spring, on spring failure the cycle counter for that spring is stopped and shuts the machine down.
To enable testing at elevated temperatures, the machine is fitted with a system which floods the springs with preheated oil. The hot oil is pumped to the machine via flexible pipes, and spray heads to the side of the test springs are used to flood the springs. The maximum operating temperature is 125deg C.
This machine is also available as a Hot Air version if required (max air temperature 125deg C).
Valve Spring Fatigue Tester - Standard Features Include:
- Stroke 0.5 to 30mm.
- Maximum load 3000N - single spring.
- Maximum load 2000N - double spring.
- Maximum speed 2400 rpm (40Hz).
|
- 12 / 24 stations dependent on load.
- Spring failure monitors.
- Programmable test duration.
- Hot oil system for elevated temperature testing up to 125°C.
