Embodiment Construction

[0048] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0049] The idler fatigue reliability calculation system of the present invention takes the tracked vehicle idler as an object, such as figure 1 As shown, the tracked vehicle idler structure includes an idler assembly 1, an idler cantilever 2, an idler bracket 3, a car body side deck 4 and a weld between the idler bracket 3 and the car body side deck 4. Sew 5.

[0050] A tracked vehicle idler fatigue reliability calculation system, based on the dispersion of working conditions, is applied to a tracked vehicle idler control device. The tracked vehicle includes the idler and the tracked vehicle idler fatigue reliability calculation system. This embodiment also provides a computer program product, including computer program codes for executing the system for calculating fatigue reliability of tracked vehicle pulleys.

[0051] Specifically, such as figure ...

Abstract

The invention discloses a system and a method for calculating fatigue reliability of a track roller, a tracked vehicle and a program product, which are applied to the technical field of tracked vehicles, and are used for calculating the fatigue reliability of the track roller of the tracked vehicle through a multi-body dynamics simulation model, a damage response surface model and an MATLAB program on the basis of working condition dispersibility; thereby solving the problem that a traditional vehicle structure fatigue reliability prediction method cannot be based on strong randomness of working conditions and strong nonlinearity of loads, and the method is easy and convenient to calculate, easy to understand, small in calculation amount, low in cost and high in engineering applicability.

Description

technical field [0001] The invention relates to the technical field of tracked vehicles, in particular to a system and method for calculating fatigue reliability of tracked pulleys, tracked vehicles and program products. Background technique [0002] The tracked vehicle idler belongs to the tracked vehicle action system, and its function is to be installed on the side deck of the vehicle body through the idler bracket to lift the upper branch of the track to maintain the overall shape of the track when the vehicle is running. During the running of tracked vehicles, the track is excited by the unevenness of the road surface, and an alternating load perpendicular to the ground is applied to the idler pulley. Under the action of alternating loads, due to the surface roughness, the defects of the supporting pulley itself and the design mechanism, etc., the parts where the stress concentration exists at the connection position between the supporting pulley bracket and the side de...
