PT400mini mechanical fault simulator delivered to Chang'an University Portable Vibration Simulator

The T400 mini mechanical fault simulator adopts a modular design, with a cantilever rotor installation and a single rotor disk structure. It is equipped with vibration acceleration sensors and has corresponding standard installation screw holes and brackets, which facilitate the installation and debugging of various sensors. This simulator has powerful fault simulation capabilities and can accurately simulate various common machine faults:

1. Gear faults: covering different types of faults such as gear wear, tooth breakage, cracks, and missing teeth, providing the possibility to study the vibration characteristics of gears under different damage states. By simulating these faults, researchers and students can deeply analyze the causes, development process, and impact on the entire transmission system of gear failures.

2. Rotor unbalance and misalignment: It can simulate static and dynamic unbalance, as well as unbalance, misalignment, and looseness of the county arm rotor. These faults are quite common in actual rotating machinery equipment. By conducting experiments on simulators, users can better understand the impact of unbalance and misalignment faults on equipment vibration, and thus master effective fault diagnosis methods.

3. Bearing faults: It can simulate various situations such as bearing outer ring, inner ring, rolling element, cage, and comprehensive faults. As a key component of rotating machinery equipment, bearings have a high failure rate. The PT400 mechanical fault simulator provides a good experimental environment for studying bearing fault characteristic frequency recognition and fault characteristics at different speeds,

4. Other functions: In addition to simulating common faults mentioned above, this simulator can also perform single-sided dynamic balancing experiments, enemy impact experiments, start stop testing methods, and support practical machine vibration testing such as gear eccentricity, belt faults, and resonance, with rich functions

Enable it to meet the needs of different research directions and teaching scenarios. 3、 Delivery process

During the delivery process, the equipment supplier works closely with relevant departments of Chang'an University to ensure the smooth progress of the entire delivery process. The supplier shall first safely transport the PT400 mechanical fault simulator to the designated laboratory of Chang'an University at the time and location specified in the contract. After arrival, professional technicians quickly carried out the installation and debugging of the equipment. During the installation process, technicians strictly follow the requirements of the equipment installation manual, assemble each module of the simulator accurately, and monitor the sensors

Thoroughly connect and inspect electrical circuits to ensure the correct installation of equipment hardware. After installation, enter the debugging phase. Technicians use professional testing instruments and software to comprehensively test the various functions of the simulator. For the fault simulation function, different types and degrees of faults are set one by one, and vibration data of the equipment under fault conditions is collected and compared with theoretical values for analysis. The parameters of the simulator are fine tuned to ensure the accuracy of fault simulation. After intensive debugging, all performance indicators of the PT400 mechanical fault simulator have reached or exceeded the contract requirements and passed the acceptance smoothly.
