摘要
拖拉机(Tractor)是设计用于在低速下提供高牵引力(或扭矩)的工程车辆,用于牵引拖车或其他辅助机械器具,广泛用于农业、采矿或建筑的拖车。在我国农业机械现代化背景下,国内拖拉机厂商响应国家号召,加快推进农业机械化、设施化、智能化,为国家迈入农业强国创造基本条件。大马力拖拉机作为农业装备的核心,其技术发展也关系着国家农业机械化程度和农业现代化水平,所以提高自主研发国产大马力拖拉机技术水平是推进加快现代化农业发展的必然需求。我国大马力拖拉机驾驶室技术从原有满足基本产品功能逐步向更舒适、技术更先进发展。降低大马力拖拉机噪声是一个新兴的问题,除了需要满足噪声国家标准外,还有助于提高农民的生产力。噪声也是影响使用者身体健康的一大因素。文章根据某款大马力拖拉机噪音测试情况,讨论了噪音源研究、各种降噪措施,以及先进的降噪技术,以达到国家标准和满足用户对驾驶室舒适性的要求。
Tractor is an engineering vehicle designed to provide high traction(or torque)at low speed,which is used to tow trailers or other auxiliary machinery.Trailer widely used in agriculture,mining or construction.In the context of China's agricultural machinery modernization,domestic tractor manufacturers respond to the call of the country to accelerate the promotion of agricultural mechanization,facilities and intelligence,and create basic conditions for the country to enter the agricultural power.As the core of agricultural equipment,the technical development of high-power tractors is also related to the degree of national agricultural mechanization and the level of agricultural modernization.Therefore,improving the technical level of self-developed domestic high-power tractors is an inevitable demand for promoting the development of modern agriculture.The cab technology of high-power tractors in China has gradually developed from meeting the basic product functions to more comfortable and advanced technology.Reducing the noise of high-power tractors is an emerging problem.In addition to meeting the national noise standards,it also helps to improve the productivity of farmers.Noise is also a major factor affecting the health of users.Based on the noise test of a high-power tractor,this paper discusses the noise source research,various noise reduction measures and advanced noise reduction technology to meet the national standards and meet the user's requirements for cab comfort.
