What is a Universal Testing Machine?

 

A universal testing machine (UTM) is an electromechanical testing system that applies a tensile force to raw materials or components to test for both tensile and compressive strength. It is widely used for both small and large load testing in quality control or research projects, etc.​ Universal testing machines include electromechanical and hydraulic systems to perform static testing, including tensile, compression, bend, peel, tear, shear, friction, puncture, and other mechanical tests.

Working Principles

Operation of the universal testing machine is achieved by hydraulically transferring the load from the test specimen to a separately mounted load indicator. This system is ideal because it replaces the transmission of loads through levers and blades, which are prone to wear and damage from the impact when the specimen breaks. The load is applied by a hydrostatically lubricated plunger. Master cylinder pressure is transmitted to the cylinder block of the swing-out dynamometer system within the control panel. The cylinder of the dynamometer is also designed to be self-lubricating. The deflection of the pendulum represents the absolute load exerted on the test specimen. The return motion of the pendulum is effectively damped to absorb energy in the event of sudden fracture of the specimen..

 
Components of Universal Testing Machines (UTM)

 

 
Primary components make up a universal testing machine as follow:
 
Load Frame

A universal testing device's load frame can be constructed using a single support or two supports. The upper cross head, lower cross head, and table that the specimen is set on for the compressive strength test make up the load Frame.

Upper Cross Head and Lower Cross Head

The test specimen is clamped at one end using the top cross head. The moveable cross head in the load frame is the lower cross head, and its screws can be loosened and tightened to change the cross head's height. A tapered slit runs through the middle of each cross head. The tensile test specimen is supposed to be held in place by a pair of racking jaws that are located in this slot.

Hydraulic Power Unit

This component consists of an oil pump that feeds steady oil into the load unit's main cylinder. The specimen is loaded more easily thanks to this flow. An electric motor and sump operate the oil pump in a hydraulic power unit.

Load Measuring Unit

The pendulum dynamometer in this device travels with the flow of non-pulsating oil in a tiny cylinder. Through a pivot lever, the pendulum is linked to the piston. Depending on the load placed on the sample, the pivot lever will flex. The load pointer is created from this deflection and shown as the weight on the dial. A knob in the load measuring device allows the user to change the load application range. The measurement unit's precision determines the machine's accuracy rate.

Control Devices

The controls could be hydraulic or electronic. Switches are used by electric control devices to move the cross heads and turn the unit on and off. Two valves - the right control valve and the left control valve or release valve - make up a hydraulic control device. The specimen is subjected to load using a proper control valve.

Functions of Universal Testing Machines

 

 

Tensile Test

Tensile testing is one of the most typical uses of UTM, which involves pulling a material apart until it breaks. This helps determine how strong, stretchable and rigid the material is.

Compression Test

The opposite of tensile testing is compression testing. Universal testing machines can be used to squeeze items until they reach a certain density, move a certain distance, or break.

Peel Test

The average peel force of a material can be determined by performing a test called a "peel test," which is similar to a "tensile test" but involves separating two materials that were previously bonded together.

Bend Test

In a bend test, the ends of a span of material are held in place while a machine applies force in the center of the span until the material breaks or travels a predetermined distance. The flexural strength and flexural modulus of a material are determined through bending tests.

Puncture Test

To determine the level of puncture resistance of a material sample in a puncture test, the sample needs to be pierced until it is punctured.

Single Column Universal Testing Machine

 

Single-column universal testing machines, also often called C-frame testing machines because of their shape, have the smallest footprint and capacity. These systems are typically used on benchtops and have load capacities ranging from a few ounces to approximately 1,000 pounds. Virtually every single-column machine is electromechanical and uses small servo motors to provide power and control. If you have a testing application that requires more than 1,000 pounds, you will need to use a two-column machine or you may cause the machine to buckle.

Two-Column Universal Testing Machine

 

Two-column test benches are also known as H-frames due to their design. The H-frame structure is extremely strong and was the basis for some of the earliest universal testing machines. Capacities of these systems range from 500 pounds to over 100,000 pounds. Two-column UTM can be electromechanical or servo-hydraulic. Generally speaking, hydraulic presses are better suited for extremely repetitive testing of high-strength materials in a production environment. Electromechanical machines are more versatile in terms of speed and stroke length, which makes them more suitable for R&D environments where many different types of testing can be performed.

Precautions for Use and Storage of Electronic Universal Testing Machine

 

 

Double Column Universal Testing Machine

Read the Instructions

Before using the electronic universal testing machine, the operator should read the product manual carefully and be familiar with the technical indicators, usage methods and operating specifications of the equipment. The operation process must be strictly carried out in accordance with the operating specifications. Operators who use the equipment for the first time should be guided by skilled operators before they can operate alone.

Preheating

The electronic universal testing machine needs to be preheated, which takes about 15 minutes, and then the test can be carried out. If the test machine shuts down or the equipment suddenly stops automatically during the test, you need to wait for one minute before restarting.

Moisture-proof

The center beam platform, workbench and other areas of the electronic universal testing machine need to be moisture-proof. In addition, anti-rust oil should be applied to these parts frequently to protect the equipment from rust. In addition, it should be noted that the operator needs to carefully dust and clean the equipment before applying anti-rust oil.

Concentrate

During the entire operation, the operator needs to maintain a high degree of concentration and cannot leave the test site midway. In addition, operators need to closely observe changes in testing machine data, because once an emergency hazard occurs during operation, operators need to turn off the power immediately to ensure safety.

Turn off the Power in Time

If the load sensor needs to be replaced during the operation of the electronic universal testing machine, the power of the equipment must be turned off, and the software system of the control equipment must be disconnected from the equipment before the sensor can be replaced. In addition, it should be noted that the leads of the load cell cannot be directly plugged or unplugged while the power is on, otherwise it will cause damage to the equipment.

Correct Transportation

If the electronic universal testing machine needs to be transported, the transporter needs to maintain the horizontal transport direction as much as possible, and the entire process needs to be as stable as possible without excessive vibration. In addition, the beam part of the electronic universal testing machine cannot be moved during transportation. Excessive force may damage the sensor.

Q: What is the purpose of tensile testing in UTM?

A: A tensile test, or tension test, is done by pulling on a tensile (normalized) specimen, to determine how the material reacts to forces being applied in tension. As the material is pulled, you determine the material's tensile strength and how much it will elongate.

Q: How do you use a universal UTM testing machine?

A: To perform the test with UTM, the sample is placed between the two jaws and clamped firmly to perform either tension or compression test. Once the sample is placed in its right position, the jaws are pulled apart to apply tension on the sample. The tension is applied to the sample until it reaches the fracture point.
