NVH really so mysterious? T99 with the strength to speak — visit Pentium laboratory
on the car issue, domestic consumers are always more stringent, not only to look for a model, interior, space, power careful study of this type of vehicle, such as details of silence is also of great concern, no doubt is closely related to NVH. According to JD Power’s IQS survey, the main users of the product have complained that the car is about 30 percentage NVH-related. 27 honor to be invited to participate in a series of forums say the Pentium II Pentium said static activity [middot; Yue middot; talk] NVH interview activities, Zero visited the “Integrated State Key Laboratory of Automotive Safety and Noise and Vibration Control”, by sophisticated technology and intuitive display interesting experiments are combined with NVH experts together Secret “car sector metaphysics” — NVH.
NVH, N refers to Noise noise, V refers Vibration Vibration, H refers Harshness harshness. NVH performance directly affects user comfort and feel of a car a sense of quality, but also best reflect the level of integrated technology OEMs, so the major automobile manufacturers attach great importance to this performance. T99 Pentium Pentium family as the new T-series the third in the new model, the new Pentium brand’s flagship model, the government declared it a collection of the most stunning design style, work most conscientious use of materials, cutting-edge technology. That it can carry the banner of the brand, the brand up to shoulder the heavy responsibility? We find out.
NVH laboratory test set-vehicle semi-anechoic chamber, by the acoustic apparatus, environmental control system, the exhaust gas discharge system or the like. Mainly for passenger noise transfer path testing, sound absorption performance vehicle compartment, the vehicle vibration noise inside and outside the objective and subjective evaluation. During the experiment the art to directly open a Mercedes GLC comparison site, better sound insulation door to see who, through rigorous professional data acquisition, the results show, the Pentium in tire noise and road noise and T99 can be substantially phase GLCComparable, in terms of wind noise and mechanical noise T99 GLC even better than we have.
NVH Pentium T99 of the subject is not the same the level of competing products, but luxury brands Mercedes-Benz, Volvo and other front-line. All data is displayed T99 vehicle NVH performance is superior to all Mercedes-Benz GLC, Volvo XC60 and other luxury car brands in the noise, wind noise, road noise, T99 is no doubt the consumer to create a quiet interior space, it has a top comfort, bring to the owners of the most distinguished driving experience.
Laboratory abnormal noise is mainly used for vehicle analog vehicle road excitation abnormal sound test and evaluation at different temperature, humidity and light conditions, extreme heat in extremely cold, sitting on the T99 comfortable seating experience nearly 16 kinds of continuous analog bumpy road, in addition to the normal driving period outside voice, almost inaudible other abnormal sound. This is also due to focus on the T99 uses the NVH performance of the US Cooper Tire low noise tires, front and rear suspension were also adopted McPherson independent suspension and multi-link independent suspension. Wherein generating the multi-link suspension vehicle stability control, reduce friction with the road surface of the tire aspect has incomparable advantages, is a combination of ride comfort and handling stability of the suspension system, which effectively reduces the passage manic .
T99 uses the same red flag 20T engine and hydraulic HS5 will be used only high-end car mount, this engine design early conducted noise and vibration of the engine bench test for a single product, and effectively reduce the noise and vibration reducing engine body. In the transmission path of the semi-anechoic chamber, we also experience a T99 steering wheel jitter suppression results, speed from 700 rpm soared all the way to 4,000 rpm, while the pile of stones on the steering wheel remains motionless three irregular, so a stunning performance enough to show the T99 Pentium did not lose the luxury cars in terms of NVH.
In addition, noise in the cabin, the use of a EVA + PET combined suction insulation material, the surface density of the EVA reached 4800, far more than 3500 of its class, the driver is further reduced into the passenger compartment of the engine noise. In T99 goal setting process engineering acoustics package for 44 kinds of acoustic ceiling package parts, carpet, insulation pads, etc., FAW Car Pentium Development Institute is defined by the material, acoustic insulation curve setting, and suppliers of process monitoring and the sample re-inspection, to ensure that the acoustic loading packages with high standards. T99 vehicle acoustics package timber and performance to the level of Audi models, fully optimized for the user to create a super-quiet interior space.
Pentium T99 Comparative Pentium [ 123] T77 of the “light off learning” upgrading to design quot; light charm school ‘, creating a clear water chestnut stereoscopic body, more stretch lines, firmness and flexibility, burly Founder, which perfectly fit positioning the brand’s flagship model. either interior or exterior configuration, Pentium T99 has been given enough sincerity, especially its NVH levels, will allow more car owners on the future of the market to have a higher confidence, domestic brands for the second rise Pentium, T99 just want to prove with the attitude, the pursuit of perfection, happiness will further ……
