随机过程理论的发展虽仅20年的厉史,但在各工程领域已广泛地应用。近年来拖拉机行业在这方面的研究还仅仅是个开端。本文结合拖拉机的工作条件,特点,探讨了运用这一理论研究拖拉机振动和强度的原則和方法。所提出的问題及研究方法较为新颖,对本行业的研究、设计和试验工作有一定的启发和参考价值。 Although the development of stochastic process theory is only 20 years of history, it has been widely used in various engineering fields. In recent years, tractor industry research in this area is only the beginning. Based on the working conditions and characteristics of tractors, this paper discusses the principles and methods of using this theory to study the vibration and strength of tractors. The proposed problems and research methods are relatively new, the research, design and testing of the industry have some inspiration and reference value.
