SLS尼龍3D打印賽車穩(wěn)壓腔的設(shè)計生產(chǎn)及應(yīng)用

盈普的老粉們應(yīng)該早在去年就關(guān)注過《盈普助力2019大學(xué)生方程式》的相關(guān)報道。是的，早在去年6月初盈普小編就參與到交大賽車隊進(jìn)氣喉管及穩(wěn)壓腔體的初代設(shè)計打印工作中，今年盈普將這一過程視頻化（為小編不太成熟的原創(chuàng)點個贊吧,更加直觀的為大家展現(xiàn)SLS 3D打印穩(wěn)壓腔的設(shè)計生產(chǎn)過程。

點擊視頻前，先帶大家介紹一下這款賽車穩(wěn)壓腔的前情回顧：

賽車隊組委會出于對安全的考量，對所有參賽車輛的發(fā)動機(jī)進(jìn)氣流量做出了嚴(yán)格的限制，因此如何合理的設(shè)計制造車輛進(jìn)氣系統(tǒng)成為所有參賽隊伍都不得不面對的難題。對于結(jié)構(gòu)相對復(fù)雜的穩(wěn)壓腔體及其組件的制造而言，賽車隊在有限的條件下是無法采用傳統(tǒng)機(jī)加工手段來實現(xiàn)多次優(yōu)化迭代升級，因而上屆車隊隊長湯隊果斷在吸取2018年度參賽經(jīng)驗的基礎(chǔ)上，結(jié)合今年優(yōu)化升級的動力輸出系統(tǒng)方案，在組員共同努力及流場仿真分析軟件Ansys Fluent的指導(dǎo)下完成了進(jìn)氣系統(tǒng)組件的初代設(shè)計并及時的尋求TPM3D盈普為其提供SLS尼龍激光燒結(jié)工藝的生產(chǎn)支持。

正如所有的初代設(shè)計都不會近乎完美，小編有幸代表TPM3D盈普的技術(shù)支持走進(jìn)賽車隊學(xué)生創(chuàng)新中心實驗室，經(jīng)過交流得知打印的初代穩(wěn)壓腔在發(fā)動機(jī)提速后會出現(xiàn)輕微形變，經(jīng)過進(jìn)一步探討分析得知部件在設(shè)計之初過分考慮了減重因素，忽略了發(fā)動機(jī)性能及穩(wěn)壓腔結(jié)構(gòu)的變化因素，整體部件壁厚減少為2018年參賽車輛穩(wěn)壓腔體零件的1/2，進(jìn)而導(dǎo)致零件剛性不足的情況。明確原因后雙方現(xiàn)場敲定方案，賽車隊動力組從設(shè)計端著手提高零件剛性，TPM3D盈普則從材料及工藝端適配合適的方案。在雙方共同努力下進(jìn)氣穩(wěn)壓腔二代設(shè)計很快就誕生了，動力組通過外置加強(qiáng)筋等方式改善了初代設(shè)計零件剛性，TPM3D盈普適配了高剛性的玻纖尼龍Precimid1172Pro GF30 BLK材料打印搭配盈普獨有的零件強(qiáng)化處理工藝，在多重保證下二代進(jìn)氣穩(wěn)壓腔組件成功的通過了發(fā)動機(jī)臺架測試以及整車道路測試。2018年新車發(fā)布會車輛配備的就是二代穩(wěn)壓腔組件。
