如何提高梁的弯曲强度,增大梁的承载能力,在机械工程中可以采用的方法有合理布置载荷、合理布置梁的支座、合理选择梁的截面形状、采用等强度梁等。文章介绍了这些方法的应用,以便为机械结构中梁的合理设计提供理论依据。 How to improve the bending strength of the beam and increase the carrying capacity of the beam can be reasonably arranged in the mechanical engineering. The bearing of the beam is reasonably arranged, the cross-sectional shape of the beam is selected reasonably, and the beam of equal strength is adopted. The article introduces the application of these methods in order to provide a theoretical basis for the rational design of beams in mechanical structures.
