Combined with finite element complex modal analysis and bench test
, it is of great guiding significance to improving the NVH performance by improving the material properties of the brake pad and optimizing the backplate structure of the brake pad to inhibit the brake squeal noise and to exploring the inhibition mechanism of noise, which provides a theoretical basis for reducing the noise of brake squeal.
Meanwhile, comparison of Figures 7(a) and 9(a) indicates that bench test
results conform to simulation results, which proves that designed PMMVMD suspension based on FOA-LQG control algorithm can enhance the riding performance of vehicles.
A noticeable deviation between bench test
emissions results and actual road use was established solely for this type of engine.

It is designed for VHF and UHF applications and is also suited for receiver amplifiers, RF bench test
, and mobile base station applications.
The crossover SUV is designed for action and has passed the 3,000,000km road test and 10,000 hour bench test
following European and American standards.
