Abstract: At present, the research on shell deformation of new energy reducer is mostly focused on the field of theory and simulation calculation, and there is a lack of effective test means, so it is necessary to design a set of shell deformation testing system and matching test method system, so as to calibrate the simulation results of shell deformation and check the actual strength of the shell. In this paper, based on the principle of shell deformation measurement, the overall design scheme of the test system is put forward, and the matching shell deformation testing software is designed and developed. Finally, the shell deformation test system is used to verify the shell deformation test on a certain type of new energy reducer, and the functionality of the test system is verified successfully.
Keywords: new energy vehicle reducer; shell deformation; test system; test verification; simulation calculation
減速器作為傳動系統(tǒng)中的關(guān)鍵零部件,對保證動力順利傳輸起到關(guān)鍵作用,其殼體起到支撐、保護(hù)內(nèi)部零件等作用。一旦殼體強度不足,將嚴(yán)重影響減速器的正常工作,甚至導(dǎo)致車輛的基本行駛功能喪失。而由于新能源汽車減速器“輕量化”發(fā)展策略,新能源減速器殼體厚度、質(zhì)量不斷降低,強度也受到影響,減速器殼體變形量是評價新能源減速器殼體強度的重要指標(biāo),同時殼體變形也與減速器NVH性能等指標(biāo)息息相關(guān)[1]。為探究新能源減速器殼體強度變化規(guī)律,大量學(xué)者對此進(jìn)行了深入研究。于蓬等[2]考慮軸承受力等因素建立了減速器振動特性仿真分析模型,利用該模型探究了殼體表面振動情況。袁勃等[3]基于CAE仿真分析結(jié)合殼體拉、壓應(yīng)力分析,建立了新能源減速器殼體仿真模型,探究殼體模態(tài)振動頻率。……
