Embodiment

[0016] Taking Langxing 2017 manual comfort version as the research object, its front suspension is McPherson independent suspension, and an electromagnetic linear actuation-energy feeding device (ELA-ERD) is installed on the basis of it. According to the spring inner diameter of 98mm, it is determined The outer dimension of the feeder motor is 90mm, and then the internal structure is designed, and the preliminary design parameters are shown in the table.

[0017] Table 1 ELA-ERD Outline Dimensions

[0018]

[0019] The internal structure size is designed under the constraints of the external size. In order to maximize the efficiency of the feeder motor, the structural parameters are determined for the original design of the motor. The height of each part is determined according to the profile height and the suspension stroke, and they are all fixed values. Therefore, the radial dimensions of each internal structure are optimized to obtain higher motor feed power and motor ...

Abstract

The invention discloses an optimization method of an energy feedback device of an energy feedback suspension, mainly aims at a cylindrical linear motor for the energy feedback suspension, solves the problems of complex structure parameter optimization, large calculation amount and difficult optimization of a traditional linear motor, and provides an optimization design method combining finite element and parameter combination optimization. The invention discloses a design optimization method of an electromagnetic linear energy feedback suspension, which can quickly approach to the optimal structural size through one-time parameter combination on the basis of a finite element method, simplifies the optimization process to a great extent, saves the calculated amount and can achieve a betteroptimization effect.

Description

technical field [0001] The invention relates to the technical field of automobile design, in particular to an optimization method for an energy-feeding device of an energy-feeding suspension. Background technique [0002] Cars are an important means of transportation for people to travel. According to data, as of the end of 2019, the number of cars in the country reached 260 million, of which the number of new energy vehicles in the country reached 3.44 million as of June, accounting for 1.37% of the total number of cars. Compared with the end of last year, there was an increase of 830,000 vehicles, an increase of 31.87%. Although new energy vehicles have been put on the market, bringing convenience and comfort to people, with the continuous development of industrialization, the problems of energy cleanliness and energy saving have become increasingly serious. Many scholars at home and abroad are still researching on the cleanliness and energy recovery of automobile energy....
