Embodiment Construction

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] see figure 1 , The compression mechanism of the spring at the bottom of the driver's cab is composed of a top wire 5, a support seat 4 and a U-shaped socket gasket 3. The top wire 5 is threaded, and the spring support seat 4 integrates the support and the top wire adjustment seat. By adjusting the top wire 5, the compression amount of...

Abstract

The invention provides an adjusting method for reducing vibration of a locomotive cab. A compressing mechanism is arranged for each elastic component, the bottom and a rear wall of a cab are connected with a base support and a partition wall of adjacent function chambers through the elastic components respectively, the compressing mechanisms of all the elastic components are adjusted respectively, and the rigidity of the elastic components is changed till a vibration level of the cab meets a requirement. By means of the method, vibration adjusting of a passive vibration isolation internal combustion locomotive can be conducted conveniently and effectively, the cab is not required to be hoisted, a large amount of dismounting and recovery work are not required, various tools, hoisting devices and devices are not required, and effective adjusting can be conducted only through a simple pneumatic impact wrench. A large amount of labor, materials and time are saved, collecting of vibration data can be conducted after adjusting, optimization adjusting is conducted, and the adjusting method is used for solving a vibration problem of an assembled locomotive and can be applied to an experimental study process of the vibration problem.

Description

technical field [0001] The invention relates to a vibration reduction adjustment method for a cab of a railway locomotive, belonging to the technical field of railway locomotives. Background technique [0002] Railway locomotives, especially high-speed and heavy-duty high-power diesel locomotives, transmit huge energy and frequently have vibration problems. Locomotive vibration is very harmful. It not only affects the life of components on the locomotive, but also causes serious discomfort to the drivers and passengers, which is very unfavorable to the safe running of the train. There are two main forms of vibration isolation for diesel locomotives: one is active vibration isolation, that is, the driver's cab is rigidly installed on the chassis, and elastic supports are installed between the diesel generator set and the car body chassis to reduce vibration transmission; the other is active vibration isolation. It is passive vibration isolation, that is, the diesel generator...
