Astm Lab Certification Test Environmental Vibration Testing Third-party authentication service

Provide a variety of environmental vibration testing

The purpose of vibrating screen factory test is to check whether the parameters of vibrating screen meet the design requirements. The main test items include amplitude, direction Angle, vibration frequency, resonance amplitude when stopping, noise, power, bearing temperature rise, stress and modal testing, etc. Generally, the test is carried out without load.

Product range:

Steady state vibration: rotating machinery (such as fans, generators, motors, water pumps, etc.) and reciprocating machinery (such as diesel engines, air compressors, textile machines, etc.) caused by environmental vibration.
Impact vibration: Impact vibration is the environmental vibration with sudden change of vibration level. Including forging and pressing machinery (such as forging hammer, punch, etc.) and construction machinery (such as pile driver, etc.) and blasting caused by environmental vibration.
Random vibration: Random vibration is the environmental vibration that cannot be determined in advance at any time in the future. Including road traffic and bridge vibration and residential vibration (such as house decoration, kitchen operation, etc.) caused by environmental vibration.
Mixed vibration: Mixed vibration is the environmental vibration caused by the simultaneous action of two or more kinds of vibration (such as rotating machinery and construction machinery working together) in steady state vibration, impact vibration and random vibration.
In the environmental vibration test, vibration measurement includes two types: one is the vibration measurement of the object that causes noise radiation; The second is the measurement of environmental vibration.

1. Testing standard (part)

The most commonly used vibration mode can be divided into sinusoidal vibration and random vibration. Sine vibration test method is often used in laboratory, to simulate rotation, pulsating, volatility (in ships, aircraft, vehicles,) generated by the vibration and the analysis of the product structure resonance frequency and resonance point resides validation is given priority to, it is divided into frequency sweep vibration and fixed frequency vibration, its tougher depends on the frequency range, amplitude value and test duration. Random vibration is evaluated by simulating the overall structural strength of the product and the transportation environment in the packaging state. The severity of random vibration depends on the frequency range, GRMS, test duration, and axial direction.

2. Certification services

The test report issued by Global Zhongyi has legal effect and can be used in scenarios such as the entry of supermarkets, product appeals, anti-malicious rights protection, and auctions (appeals and auctions must meet Party A's testing requirements).
