Random vibration test bed, mainly used for electronic parts of the vibration resistance, through the dynamic simulation analysis of electronic parts to determine the vibration characteristics of electronic parts, so as to test its performance for product stability and reliability.
Random vibration test is to test the ability of the product to work reliably in the random vibration environment by simulating the vibration environment of the equipment platform and using the random vibration test platform to input specific random vibration excitation spectrum to the product.
Random shaking table test generally has the following functions:
1. function test:Through the function test, the maximum vibration stress under the operating environment is applied to the product to check whether the product can work normally.
2. durability test:The ability of a product to work reliably over a given life is verified by durability testing.The durability test examines the structural strength and fatigue life of the product, and tests whether the product under a certain random vibration test bed environment produces fatigue damage, mechanical wear and other causes of life shortening or failure.As this kind of test is related to the service life, both the test strength and the test time must consider the service requirements.
3. vibration frequency response test:Through the vibration frequency response characteristic test, grasps the product dynamics characteristic, facilitates to carry on the anti-vibration design to the product.This paper only focuses on the vibration frequency response test, that is, to determine the product frequency response characteristics through the simulation of random vibration test.

Ultra mute work; The machine base uses the high quality material, installs conveniently, the operation is smooth, does not need to install the The, the control circuit digitization control and the display frequency, the PID adjusts the function, causes the equipment work to be more stable, reliable, sweeps the frequency and the fixed frequency operation way, adapts to the different profession test request To solve the interference of the strong electromagnetic field to the control circuit, and to increase the working time set, so that the test product reaches the accurate test time.
How to use:
1, the control manual to complete the procedure
2, such as Operation error so that can not work, you can use the recovery method of the steps of the input, and then set a single group or other running steps.
3, before use to press the external start switch, appears COO namely lets go, opens the key.
4, Taiwan Body:
1 The table body foot sleeve as far as possible fixed
2 power supply on/work in the output line can not be unplugged
3 Place the level as far as possible
4 components can be changed, the line should not be changed or from the connection.
5 The Taiwan body must not be all or part of the reorganization, only according to specifications for a single component and with the original confirmation password.
5, the amplitude inside the code
1. Do not adjust too large before or after the boot
2) low-key amplitude of high amplitude modulation
3 Control Panel Amplitude Knob placed in the middle position test items: placed to focus on the main point, reduce the left flat right.
4 control Box: Can not be placed on the top or underground operation
6, Inside Code:
1) reset when running or operating incorrectly
2) Control The Reset method step, each inside code only set one time to save can
3 usually must use the internal code can not be set randomly
7, Control Box:
1) The connecting line of the body must be locked tightly after hanging
2 the vibration direction switch and the output connection line are correspondence, can not connect the wrong
8, testing: Non-special test should use full wave test
9, the Taiwan body: can not produce the collision sound, the upper and lower center axis mutual touch will cause the spring steel piece rupture to be immediately shut down, amplitude modulation is adjusted small then turns on.
10, other unknown:
Do not arbitrarily change internal components and lines
11, the reason is bad:
1 The use of computer models can not be used for shaking table control
2 can not reload the driver
2, for the Ista-ia test, the operator to protect the sample, to prevent the test pieces slide out of the table;
3, gear gearbox replacement regularly;
4. Cut off all power when not working, keep clean; 5, non-staff can not operate at will
