Noise control heavy truck cab. Vehicle cab sound field is more complex, not only an external incoming noise, but also the noise generated by the internal sound source and reflected by the wall surface generated reverberation, and the cab is equivalent to a sound insulation cover, but some of the wall surface itself which is a strong noise source. The main noise sources cab noise transfer and solid gas transmission noise. Noise in which the gas is passed mainly radiated noise of the engine surface, intake and exhaust noise, fan noise and the sound of gas, the gas flow of high frequency noise; noise and solid passing mainly through the frame driveline vibration transmitted to the cab internal low-IF noise and vibration. So for the occupants in terms of safe and comfortable driving environment must have a good seal can do to ensure the heavy truck cab cab Prince, good sealing performance can effectively reduce the external noise passing cab, reduce driving ear decibels index personnel Prince heavy truck cab assembly, the safe operation of the vehicle. Heavy dump truck driving in harsh off-road environment, in the cab overturned the impact load is great, its cab strength directly affect the safety of the driver. In recent years, the dump truck cab design process began to consider the strength of the problem, but often neglected to optimize its structure. Prince cab cab in ensuring the strength and deformation meet certain requirements under the premise of reducing the quality of the cab in order to achieve both security and economic purposes. Through targeted optimization to select different combinations to achieve the balance between safety and economic purposes. Through analysis and optimization of the cab before the comparison, to meet the strength requirements of the premise, the cab obvious weight loss, improve the economic efficiency of enterprises.
