2012 season: built the first pure electric formula car in South China, won the fourth place in the CAE simulation analysis, the second place in the marketing report, and won the ANSYS video communication award and the news communication award.
2013 season: the tram group won the first place in the national marketing report, the second place in the endurance race, and the fourth place in the country in general; the diesel group won the fourth place in the national marketing report.
2014 season: The tram group won the first place in the national marketing report, the second place in the country in the horoscope, and the third place in the national efficiency test; the three dynamic items of the diesel group entered the top ten.
2015 season: won the third prize of ANSYS design report, the fifth national high-speed obstacle avoidance, the sixth national design report, the eighth national marketing report.
2016 season: won the sixth place in overall performance (fifth in the country), fifth place in the country for high-speed obstacle avoidance, sixth place in the country for design reports, third prize for the best vehicle inspection award, second prize for the ANSYS design report, MathWorks vehicles The second prize of dynamic simulation, the third prize of MathWorks control strategy development and software implementation.
2017 season: won the second place in the national total score, third place in cost and manufacturing analysis, fifth place in design report, fourth place in high-speed obstacle avoidance, third prize in MathWorks vehicle dynamics simulation, third place in lightweight design, Weilai Third place for the best electric powertrain and the most influential team award.
2018 season: ranked seventh in overall results and won the second prize. The design report is fifth in the country, the eight-character surrounds the third in the country, the endurance test is the eighth in the country, the efficiency test is the seventh in the country, and the ANSYS simulation analysis first prize.
2. Product usage and suggestions
First of all, thank your company for providing us with high-quality titanium alloy Gr5 bars for the processing of semi-shafts. The titanium alloy provided by your company has high strength, corrosion resistance and high gloss, which is very suitable for making semi-shafts. Compared with the previous year With the increased torsional strength of the high-carbon steel half shafts, the diameter of this year’s titanium alloy half shafts has been reduced, thereby reducing the size of the triple ball pin, reducing the size of the bearing, reducing the size of the knuckle, etc. The weight of the vehicle is reduced a lot, thereby improving the handling. And due to the corrosion resistance of titanium alloys, this year's titanium alloy half-shaft saves the maintenance work, which greatly improves the maintenance efficiency of the car.
The yield strength of your company’s titanium alloy Gr5 is nearly 200Mpa higher than our previous material 40Cr, and the density is only half of 40Cr. This allows us to ensure safety when designing the semi-shaft, and at the same time achieve a very significant lightweight.
Calculate the diameter of the semi-shaft according to the actual working conditions-determine the length by the layout of the whole vehicle-purchase three ball pins, set the spline parameters-output drawing processing-positioning assembly
The 2018 Weilai Cup China University Student Formula E Contest has come to an end. The Guangzhougonggongyiche Formula Team won the seventh prize in the race and won the second prize. The design report is fifth in the country, the eight-character surrounds the third in the country, the endurance test is the eighth in the country, the efficiency test is the seventh in the country, and the ANSYS simulation analysis first prize.
4. To Jinan Taida Titanium Products Co., Ltd.
With the strong support of your company, this season's E02 half-shaft has minimized the diameter of the half-shaft while ensuring a reasonable safety factor, realizing the lightweight design of the car. This is completely inseparable from your company's support. I would like to extend my sincerest greetings and deep gratitude to you. Because of your support, we were able to successfully make our own formula car, and then we were able to come to the scene of the Formula Student race, compete with the college teams from all over the country, and jointly create our racing dream. .
Finally, thank you again for your generous support to our team this season. We will never forget our original aspirations, our gratitude, and our struggles, and we will take firm steps towards greater glory.
