运用高速輕型客車能产生显著的經济效果,但是减輕自重不应影响車辆的强度和运行的安全。在最新的車辆結构中,基本上是依靠减輕承載的金属車体来减輕自重。因此,在設計新車时,設計师应注意保证旅客的安全,較合理的分布金属,建立等强度的車体結构,采用預应力的杆件和弯形断面等以减輕自重。 The use of high-speed light buses can have significant economic benefits, but reducing weight should not affect the strength and operational safety of the vehicle. In the latest vehicle construction, weight reduction is basically achieved by reducing the load carrying metal bodywork. Therefore, when designing a new car, designers should pay attention to ensuring the safety of passengers, distributing metal rationally, building a car body structure of equal strength, using prestressed rods and curved sections to reduce the dead weight.
