Today in Zhihu brushed to a hot topic: what is the outlet of 2022?
One of the answers in the hot list mentioned new energy vehicles, and this gust of wind made Tesla rise 10 times and Weilai Automobile rise 20 times. There is no doubt that with the support of the 14th Five-Year Plan strategy, it will still be full of opportunities for a long time to come. In this industry track, individuals can also take advantage of the trend.
How do we catch this? The new energy vehicle market has doubled, and the sales and profits of automobile-related parts have naturally increased several times. As an indispensable part of automotive product research and development, simulation is bound to burst with greater vitality with the expansion of new energy forces.
The hint can be seen from the current market demand for jobs.
For mechanical engineers, if you want to take advantage of the situation, the motor gearbox as the core component of the car is the best entry point, and many related positions have been opened to 30w+ annual salary.
In view of the hard skills required for the above positions, Lefang prepared a two-day training camp for "Simulation Evaluation of Motor Transmission System for New Energy Vehicles". In addition to the Operation of the Ansys Workbench software, it also provides interview guidance and free Q&A.
