Suspension & Vibration Test of China Youth Passenger Car
Project name: Suspension shock absorption performance test& structural vibration test of China Youth Car New Passenger Car
Brief introduction：Passenger comfort and vehicle durability remain two of the most important factors in modern automotive design and engineering. Excessive vibration not only significantly reduces ride quality for passengers but can also cause long-term wear and damage to critical structural and mechanical components of the vehicle. To ensure consistently high performance, improved safety, and maximum passenger satisfaction, China Youth Automotive Company recently conducted a comprehensive suspension shock absorption performance test along with rigorous structural vibration testing on their newly developed passenger car model.
The test focused on evaluating how well the vehicle’s suspension system absorbed shocks and minimized vibrations transmitted to the body. To achieve this, engineers employed Dynatronic’s DE-944 dynamic signal test system in combination with high-precision accelerometers. These instruments were used to measure the vibration values at both the upper and lower measuring points of the engine mount, which are critical locations for assessing how vibrations travel through the vehicle structure.
By carefully analyzing the extensive data collected from the DE-944 system, engineers were able to accurately determine the overall effectiveness of the suspension in significantly reducing vibrations. Special attention was specifically given to the rear section of the vehicle, particularly near the engine, as this area is especially prone to vibration-related issues and concerns. The comprehensive test results provided valuable insights into how the suspension system could be further optimized to minimize excessive vibration and thereby improve the overall ride stability and comfort.
The outcomes of this test were significant for both performance validation and design improvement:
Validation of suspension efficiency in controlling vibration transfer.
Improvement recommendations for structural reinforcement near the engine.
Enhanced passenger comfort through reduced vibration exposure.
Support for product development, ensuring the new model meets quality and safety expectations.
This case study highlights how Dynatronic’s advanced testing solutions help automotive manufacturers like China Youth Automotive improve their vehicles’ structural reliability, passenger experience, and long-term durability.
