The analytical work involves the optimization on mass flow and inlet noise based on CFD simulations, along with the bench test
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.
The bench test
is conducted on a two lane straight road in which two vehicles are parking temporarily in the lanes.
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 two-factor experiment using sample oils based on DGO3 but having different treat ratio combinations of EP agent and AW agent was conducted by bench test
and DGO4 providing better anti-wear performance was formulated as indicated in the "Formulation study" section.
A compiled method of the programmed load spectrum, which can simplify and accelerate the fatigue bench test
of a car body, is proposed and its effectiveness is checked by the fatigue simulation.
Finally, the presented method is applied on the modelling of a squealing disc brake, which shows good correlation between model prediction results and those from bench test
. Besides, because there are less indeterminate model parameters, the time for parameters tuning process is greatly reduced.
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.
