How much do you know about the functional characteristics of the steel leaf spring test machine - [Information]

The steel leaf spring is a widely cited elastic element in automotive suspension. It is an elastic beam of approximately equal strength composed of several alloy springs of equal width but not equal length (thickness can be equal or not equal). Like other metal components, the leaf springs must undergo product performance and fatigue resistance testing before they are put into use. The steel leaf spring tester is a commonly used detection instrument. Do you know about the leaf spring test machine?

Automobile springs are suspension elastic elements that are widely used in traditional cars. Its advantages are simple structure, reliable work, low cost and easy maintenance. It is both an elastic element of the suspension and a guide device of the suspension. One end of it is articulated with the frame, which can transmit various forces and torques and determine the wheel's jump trajectory. At the same time, it also has a certain frictional shock absorption effect. It is a three-killing victory, so it is widely used on non-independent suspensions.

Its disadvantage is that it can only be used for non-independent suspensions, which are heavier in weight, high stiffness, poor comfort, long longitudinal dimensions, which are not conducive to shortening the front and rear suspension of the car, and the steel plate spring pins at the connection with the frame are prone to wear.

Despite many shortcomings, steel leaf springs are still widely used in various cars. In order to improve the performance of steel leaf springs, reduce weight and improve life, variable cross-section steel leaf springs, single-piece springs, etc. have appeared.

In order to better improve the performance and better market application promotion, each type of leaf spring must be tempered and undergoes repeated pressure on the leaf spring test machine countless times, and the spring is repeatedly loaded until the spring breaks, and the data of each set of tests are recorded. Those that meet national standards can be identified as qualified products.

Functional characteristics of steel leaf spring test machine

The leaf spring test machine adopts a fully digital servo speed regulation system and servo motor with high speed regulation accuracy and stable performance as the driving system. The machines produced by different manufacturers are the factory controller as the core of the control system, and Windows is used as the control and data processing software to realize the screen display of test force, test force peak, beam displacement, test deformation and test curve. All test operations can be automatically completed on the computer through the mouse.

1. The steel leaf spring test machine adopts a high-precision, fully digital speed control system and precision reducer, and drives a precision lead screw pair for testing to achieve large-scale adjustment of the test speed, and the test process is low noise and stable operation.

2. Touch key operation mode, LCD display in real time. The display interface can display the test method selection interface, test parameter selection interface, test operation and result display interface and curve display interface, which is convenient and fast.

3. The steel leaf spring test machine has functions such as digital display of test force, continuous adjustment of test speed, automatic shutdown of sample pull-off, and peak maintenance.

4. The steel leaf spring tester can adjust the speed and slow lifting of the beam during sample clamping, and has protection devices such as overcurrent, overvoltage, and overload.

The functional characteristics of the steel leaf spring test machine include detecting deformation under vertical load of the vehicle steel leaf spring assembly, steel leaf spring stiffness test, steel leaf spring elastic deformation test, steel leaf spring stiffness test, elastic deformation amount and load deformation amount under specified load test. It is a way to check whether the automotive steel sheet spring can be used in vehicle configuration.

The above is about the functional characteristics of the steel leaf spring test machine. What do you know about? I hope you can provide you with some reference suggestions. We will publish the latest information about this type of product on our website as soon as possible to share with you.
