Problems solved by technology

However, this existing design method for spoked wheels can only provide specific shape parameters and ranges of spoked wheels. When the number of spokes, rim and hub diameters change, the shape parameters and ranges of the designed spoked wheels will no longer be applicable.

Embodiment 1

[0053] A method for designing a spoked wheel, comprising the steps of:

[0054] (1) The diameter of the rolling circle of the designed railway wheel is 840mm, and the inner radius of the rim is R w 361mm, hub outer radius R g The height of the hub hole is 100mm, the height of the hub hole is 175mm, and the axle load of the wheel set is 14 tons. Using DesinModeler of ANSYS Workbench, an internal and external closed cavity wheel model is established according to the size of the wheel rim and hub. figure 1 shown.

[0055] (2) if figure 2 As shown, the primary spoke hole 2 is drawn on the cavity wheel model 1. The primary spoke hole 2 consists of a central arc 21, an upper arc 22 positioned at the upper end of the central arc 21, a lower arc 23 positioned at the lower end of the central arc 21, and The left arc 24 and the right arc 25 respectively located on the left and right sides of the central arc 21 are formed; p on the arc line of 600.5mm; the center arc 21, the upper e...

Abstract

The invention relates to a spoke wheel design method, which belongs to the technical field of wheels, and comprises the following steps: establishing a cavity wheel model; drawing primary spoke holes in the cavity wheel model, wherein each primary spoke hole is composed of a central arc, an upper end arc, a lower end arc, a left side arc and a right side arc; arranging the primary spoke holes in a circumferential array according to the number of spokes, and performing stretching and cutting operation on the primary spoke holes to obtain a primary spoke wheel model; using finite element software for conducting wheel finite element structure stress analysis on the primary spoke wheel model, and optimizing the shape parameters of primary spoke holes; connecting the upper end arc, the left side arc and the lower end arc of the optimized spoke hole through a first smooth arc line, and connecting the upper end arc, the right side arc and the lower end arc through a second smooth arc line so as to obtain a complete spoke hole, and then obtain the designed spoke wheel. The method can be suitable for changes of various wheel design parameters, and the optimal performance design of the wheel can be achieved.

Description

technical field [0001] The invention belongs to the technical field of wheels, in particular to a method for designing spoked wheels. Background technique [0002] The wheel set is a very critical part of the railway vehicle, which is directly related to the safety and reliability of the train operation, and has an important impact on the running quality and ride comfort. The vibration and impact between the wheel and rail is an important source of fatigue failure and wear of the vehicle and the track. The vibration and noise of the wheel and rail have a serious impact on the comfort of the train interior and surrounding environment. Reducing the weight of the wheel and improving the design of the wheel structure are effective measures to solve these problems. The austempered nodular cast iron spoke wheel can not only reduce the weight of the wheel, but also reduce the vibration and radiation noise of the wheel, and due to the self-lubricating effect of the austempered nodul...
