Function
1. Structure Strength of. 2. Loosening of the conjugate. 3. Protect material from wear and tear. 4. Damage to parts. 5. Poor contact of electronic components. 6. Circuit short circuit and intermittent instability. 7. The standard value deviation of each part. 8. Screen out defective parts in advance. 9. Find the resonance relationship between parts, structure, packaging and transportation process.
Advantages of using a vibration testing machine
. During design, damage points and defective points can be analyzed
b. During quality control, differences and defective points produced in each batch of products can be analyzed< br/> . During production, it can be completely vibrated and measured at the same time, so that the defective rate of products can be detected early.
d. Durability measurement allows products to last longer and non-durable components to be improved early, and the company's brand reputation will be better.
Product Usage
The vibration testing machine is used to detect whether the product will produce collisions and vibrations during transportation, use, and storage, causing the product to become defective in a certain period of time, seriously affecting the use of the product and causing unnecessary economic losses. , in order to avoid this situation from happening, we must know the vibration resistance life of the product or components in the product in advance.

&Test load (~HZ) (~HZ).
&.Frequency modulation function (~HZ, ~HZ customized by customer) Any frequency within the frequency range must be within (acceleration amplitude &)
&. Frequency sweep function (~HZ, ~HZ customer-defined): upper limit frequency/lower limit frequency/time range) can arbitrarily set the true standard to sweep back and forth Frequency
&. Programmable function (~HZ, ~HZ customized by customers): each segment can be set arbitrarily (frequency/time) and can be cycled.
&. Frequency multiplier function (~HZ): The segments increase in multiples, ①. Low frequency to high frequency ②. High frequency to low frequency ③. Low frequency to high frequency and then to low frequency/cyclable
&. Logarithmic function (~HZ, ~HZ customer-defined): ① .Lower frequency to upper frequency ②.Up frequency to lower frequency ③.Down frequency to upper frequency and then to lower frequency mode logarithmic/recyclable

.Full-function computer control (purchased separately): If you want to connect the communication interface to a computer for control, storage, recording, and printing functions, you need to purchase an interface card program computer.< br/> .Precision: frequency can be displayed to .Hz, precision to .Hz
.Display amplitude acceleration (purchased separately): If you need to see the amplitude, acceleration, acceleration, and accurate numbers, you need to purchase a measuring instrument separately.< br/> .Acceleration (unit:)
Acceleration =. (frequency HZ) D (amplitude)
Example: HZ acceleration =.=
The maximum acceleration at any frequency cannot be greater than

Amplitude=/(.)
Example: Hz amplitude=/(.)=
The amplitude cannot be greater than
at any frequency. Acceleration and amplitude conversion=./
.The higher the frequency, the smaller the amplitude
