Precision vibration testing machines are widely used in reliability testing of electronic products. Here are some specific cases:
Performance testing of mobile phone vibration motors: The vibration test bench developed by Huachen Heyi has been applied to the performance testing of mobile phone vibration motors. This test bench has a wide frequency range and precise acceleration control, which can truly reproduce the complex vibration state of mobile phones in various usage scenarios such as falling, button operation, and game feedback. By accurately simulating the vibration environment under these actual working conditions, engineers can comprehensively test key indicators such as motor start-up response time, vibration intensity linearity, and stop residual vibration, thereby identifying optimization space for motor structure or drive circuit, and improving the timeliness, consistency, and delicacy of vibration feedback.
Fatigue life testing of electronic component solder joints: As an important implantable medical device, the solder joints of the internal electronic components of cochlear implants may be subjected to vibration pressure in daily use or accident scenarios such as head impact, leading to fatigue failure. The vibration test bench of Huachen Heyi has the ability to simulate the 200-1000Hz shock spectrum, which covers the typical vibration characteristics in head impact events. Through the cyclic loading mechanism, the test bench can evaluate the fatigue life of solder joints, quantify the failure cycle of solder joints under repeated stress, reveal potential risk points, optimize welding processes and material selection, and reduce the failure probability of cochlear implants under extreme conditions.
Reliability testing of new energy battery modules: When a certain new energy battery module resonates in the low frequency band of 5-18Hz, the bracket fracture rate skyrockets from 0.3% to 19%. By using a precision vibration testing machine for testing, it is possible to simulate the vibration environment that battery modules may encounter during transportation and use, helping engineers discover resonance problems of battery modules at specific frequencies, thereby optimizing the structural design of battery modules and improving their reliability.
Aerospace electronic component testing: A domestic aerospace technology enterprise used Huachen Heyi's vibration test bench to conduct a new aircraft engine ignition vibration impact simulation test. This test bench breaks through the limitations of traditional equipment single axis simulation by using multi axis synchronous vibration technology and high-frequency impact waveform reproduction algorithm. The maximum acceleration peak reaches over 1000g, and the frequency covers the range of 0.1Hz to 3000Hz. It accurately reproduces the extreme vibration impact environment of rocket engine ignition at high altitude, providing high standard verification for the safety and reliability of aircraft power systems.
