Embodiment Construction

[0035] The following is attached with the manual Figure 1-17 , the battery pack support structure of a certain pure electric truck type is taken as an example to illustrate the main process of the present invention:

[0036] (1) Acceleration signal acquisition of battery pack support structure test site

[0037] Acceleration signal collection is performed on the key areas of the vehicle frame and battery pack support structure on the bad roads of the test site. The bad roads mainly include: washboard road, Belgium, twisted road and long wave road, etc. The layout of the acceleration sensor is as follows: figure 2 As shown, four three-dimensional acceleration sensors are arranged on the left and right sides to measure the three-dimensional acceleration of the battery pack support structure, and provide target response signals for the virtual iteration of step 4. image 3 It is the time-domain signal of acceleration in three directions at position 1 on the left side when the ...

Abstract

The invention belongs to the field of new energy automobiles, and particularly relates to a method for road load spectrum of a battery pack support structure of a pure electric truck. The method is based on a multi-body dynamics principle. A rigid-flexible coupling multi-body dynamic model consisting of a seven-channel virtual test bed, a battery pack bracket and a whole frame is established. Themethod comprises the following steps: by taking battery pack bracket acceleration collected by a test field as a target response signal, reversely obtaining force boundaries of a virtual test bed andactuators of a frame by adopting a virtual iteration method, namely, a road load spectrum for fatigue analysis of a battery pack bracket; and based on the obtained load spectrum, analyzing the fatiguelife of the battery pack support structure. According to the method, the correlation between the fatigue analysis of the battery pack bracket structure of the pure electric truck and the road durability test of a real vehicle test site is ensured. The problem that the fatigue life of the battery pack bracket structure cannot be quantified by a traditional method is solved. The development periodis effectively shortened and development cost is reduced.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and in particular relates to a method for road load spectrum of a battery pack support structure of a pure electric truck. Background technique [0002] With the rapid development of my country's economic level and automobile industry, the number of automobiles has also increased rapidly. The increasingly popular automobiles bring convenience to life and promote social progress, but also bring serious environmental pollution and energy shortages. The research and development of high-efficiency, energy-saving and low-emission pure electric vehicles is the only way to solve the above problems. Therefore, domestic and foreign car companies are increasing investment in the research and development of pure electric vehicles. Pure electric vehicles have become the future development trend of the automotive industry. [0003] The battery pack is the most massive part of a pure electric truck, and the ...
