What does automotive NVH mean?

1 Answers

Automotive NVH refers to Noise, Vibration, and Harshness, which is an English abbreviation for Noise, Vibration, and Harshness. This is a comprehensive issue that measures the manufacturing quality of automobiles. Here is some relevant information: 1. The generation of automotive vibration and noise is not independent but closely related. Noise originates from vibration, and these three factors—vibration, noise, and comfort—are closely interconnected. It is essential to reduce vibration and noise while improving ride comfort, ensuring product safety, environmental friendliness, and performance. 2. An experiment on NVH standards showed that when using a car preferred by customers for testing, driving on a relatively smooth cement-paved road at a speed of 40 km/h, if the NVH of European cars is taken as 100% standard, Japanese cars are 75%, and Korean cars are 50%.

Factors affecting a vehicle's 0-100 km/h acceleration time are as follows: Torque: Torque, in simple terms, represents how much force is available. The greater the torque, the more force is applied to propel the vehicle, resulting in naturally faster acceleration. The 508L's 0-100 km/h acceleration is 7.23 seconds with a maximum torque of 300 Nm, while the hybrid version of the Accord has a 0-100 km/h acceleration time of 7.5 seconds with a maximum torque of 175 Nm. Transmission efficiency: The transmission serves as the medium for power delivery and inevitably involves power loss. The higher the transmission efficiency, the better the acceleration performance. Generally, transmission efficiency ranks as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The Peugeot 508L is equipped with an 8-speed automatic transmission. Power-to-weight ratio: The relationship between horsepower and vehicle weight is referred to as the power-to-weight ratio (unit is Hp/T). The higher the power-to-weight ratio, the faster the acceleration. The 508L's 0-100 km/h acceleration is 7.23 seconds with a power-to-weight ratio of 127 Hp/T, while the hybrid version of the Accord has a 0-100 km/h acceleration time of 7.5 seconds with a power-to-weight ratio of 140 Hp/T.
