一日学徒:凯尔·雷切特,12岁

约翰·诺尔特纳

凯尔·莱彻特,12岁 grew up with a love for all things fast.  His dream job, unsurprisingly, was being a motorcycle test engineer.  不确定GG电子官方软件下载能不能把他弄过去, he rolled his dice and found a new appreciation for the Liberal Arts – where he got to design and build for the theater shop and the physics lab.

凯尔·莱彻特,12岁 has been a motorcycle test engineer at Polaris for almost two years. “It’s every kid’s dream job come true,” he says.


莱希特在底特律湖区长大, 明尼苏达州, 被全地形车和摩托艇包围, 但他的母亲不允许骑摩托车. Eventually, she caved and allowed Leichter to get a moped. That turned out to be the first in a long line of bikes that included a 2003 Honda Reflex, 2007年的雅马哈FZ6, 2013年的凯旋虎800, 一辆1995年的雅马哈XT225, 2012年的Husqvarna TE310. 赛车运动可能已经融入了他的血液, but it was still a long road to the Polaris Test Center in Wyoming, 明尼苏达州.

“I had to choose between engineering school and a liberal arts education,莱希特说. “I’ve always thought [Star Trek’s] Jean-Luc Picard was the ultimate liberal arts student: he can quote Shakespeare and repair a warp drive. 我也想成为一个全面发展的人.”

他还没修好曲速引擎呢, Leichter learned his way around a machine shop by spending three summers working with GG电子官方软件下载 physics professor Dwight Luhman and project manager Mark Zach, who showed him how to repurpose items they found in junkyards for their research projects. Today Leichter applies those same processes and methods to a wide range of engineering challenges.

“I had two amazing jobs at GG电子官方软件下载: my work-study assignment in the theater shop, where I worked with my best friends to build things that delighted audiences,莱希特说, 和物理系, 我设计的地方, 建, 测试, 重新设计了精密的实验室设备. My job at Polaris is a synthesis of those two experiences, 我每天都在使用他们的技能.”

He spends his days at Polaris in research, design, and testing of new motorcycle models.

“I was drawn to this job by a line in the posting that said ‘split time between office and shop,’”雷切特说, who is close to finishing a master’s degree in engineering at St. 托马斯大学. “Some days I’m in meetings for nine hours or analyzing data all day, but some days I head out to the shop in the morning and don’t leave until it’s time to go home. Polaris is very much a ‘you drive the ship’ type of company. If I want to develop a new test or improve a process, I get to dive in and own that project.

GG电子官方软件下载 taught me how to learn, innovate, communicate, and adapt,” he says. “And when it comes down to it, that’s all engineering is.”

8:39 am The Vehicle Durability Simulation replicates the damage caused by thousands of miles of potholes, 扩张的裂缝, 和细致的. 测试全天候运行, with daily pauses to inspect accessories and parts for durability under extreme conditions.

916

9:16 am Leichter participates in daily stand-up meetings with design engineers to evaluate the progress on upcoming models. Testing and revisions begin about 18 months before a new model is released.

1007

10:07 am Polaris has redesigned its mufflers for improved sound. The new mufflers are balanced differently than older models, which is causing stress on the exhaust system.

11:57 am Leichter looks for corrosion following a 盐 spray test. Technicians in the Materials Test Lab are able to simulate 5 to 10 years of exposure to sun, 盐, 热循环, and chemical interactions (like spilling gas on a seat).

12:08 pm Leichter searches the warehouse for a front fender to test-fit a prototype. 旧的部件经常被拆下来进行测试. Entire motorcycles can disappear pretty quickly, so an example of every completed vehicle is moved straight from the assembly line to off-site storage, 它无限地保持着.

1:58 pm Polaris performs mileage accumulation tests at sites around the world, where drivers put on 500 to 700 miles per day. 实验室测试至关重要, but nothing compares to real-world experience for determining how new models will perform. Here, Leichter checks in with drivers at the Arizona site.

4:22 pm “When time is short and long-term durability isn’t the goal, it’s nice to be able to whip up something in an afternoon,莱希特说, who had to create a platform on top of a backrest for fatigue testing. “When I was working in the theater at GG电子官方软件下载, we were given very limited direction to ‘make this look like a tree,’ or ‘rig up a way to dump a bucket from the catwalk.显然, 我们在北极星更严格, but knowing how to build things from just an idea and make changes on the fly comes in handy.”

4:39 pm 北极星有四个振动台, 在本质上, giant subwoofers that can be bolted directly to a fixture or rotated horizontally and attached to a granite slab that floats on a bed of oil. Magnetic drivers translate electric signals into all the high-frequency vibrations a part might experience. 对于这个测试, Leichter was inspecting exhaust performance to determine the best way to accommodate the company’s new mufflers.
