Major Differences Between the Electrodynamic and Servohydraulic Test Machines

Servohydraulic Test Machines

There are different kinds of tests that the manufacturing units have to perform on the products on a daily to get the analysis of the product and its suitable requirement. There are some standards that every material needs to follow to get the desired form of product that will be at the end of the process. These testing machines are built for different purposes like testing the compression, tensile strength, fatigue, hydraulic pressure etc., and they are necessary for all manufacturing plants after they are tested. The machines like electrodynamic test machines and servohydraulic testing machines have been in use for decades, and they are still functioning for different purposes and research carried out by the plants to get accurate information on the compatibility of the raw materials in use.

The machines are used in major factories, and they check the performance capacity. The fatigue tests are done with the help of these machines, and there has been modernization, and a few changes in the machines by the base use remains the same.

Understanding the Key Differentiations between the Two Test Machines

Let us now look at some of the major differences of the electrodynamic and servohydraulic test machines:

Load displacement:

A significant distinction between the two kinds of machines is that the heap and dislodging execution of a servohydraulic actuator (contingent upon power pack size) can be arranged to convey higher powers at higher paces. Servohydraulic actuators can convey stacks up to 3 mN (670 kips). Low power actuators can perform tests at rates to 200 Hz.

Test speed

The machines are used for different kinds of purposes; when there is a need to perform slow-speed, high-speed dynamic, and fatigue tests up to 15 Hz, the electrodynamic machine is utilized, and when there is a need for higher test speeds and higher forces, the servohydraulic test system is a better option in that case.

Noise Levels

The electrodynamic creates lower noise than the servohydraulic machine, and this is a great advantage as the machine is used on a daily and when the right one is utilized, there will be a lesser amount of noise pollution in the factory unit or the testing area which does make a major difference in the long run. Electrodynamic test machines all utilize noise-free high goal computerized position encoders, which convey further developed control quality and long-haul security over servohydraulic test machines that utilization Lvdt’s. Late improvements have made it conceivable to arrange encoders on servo hydraulic-driven actuators.

Oil Leakage

The servohydraulic machine leaks more oil and is noisy than the electrodynamic machine, and this can be a major reason to choose the electrodynamic machine. Since the machine leaks lesser oil, it is also quiet and reliable. Therefore, it is better to use the electrodynamic option.

Which one to Buy?

It is better to get the electrodynamic testing machine due to its reliability and ease of working with properties. It is now easy to get these machines as they are also available online and are just one click away.
