Inventor of the Month - March 2013

Autodesk has named CNR Changchun Railway Vehicles Co., Ltd. (Changchun) as the Inventor of the Month for March 2013. Changchun Railway Vehicles main focus has become the design of railway vehicle passenger seats that are more attractive, comfortable and stable.

The problem with most train seats on subways, high speed trains and other urban railways is that passengers can easily slide forward when the train accelerates or decelerates, making the seating experience less than optimal. Changchun Railway Vehicles has improved on this uncomfortable situation by creating a curved, stainless steel railway seat designed with Autodesk Inventor software.

Using Inventor software as part of Autodesk Product Design Suite, Changchun was able to calculate the release of pressure in various curves and bends and design a seat with a fully ergonomic curve that comfortably fits the human shape. This shape provides greater control, which prevents passengers from sliding forward when the train starts or stops.

In addition to the design of the seats, Changchun also used Inventor software to determine the best way to soundly affix the seats to the floors, performing strength and stress checks on the various screws, joints and welded components. Autodesk Inventor, which includes features and functionality around tooling and tolerances, not only increases the speed of these calculations, but also generates extremely accurate calculations that help reduce the occurrence of design errors.

The Changchun team also leverages Autodesk Vault data management software to help increase the business’ product development capacity and market competitiveness. This combination of Autodesk Digital Prototyping solutions has streamlined the company’s overall design process and won a growing number of customers, particularly as European companies turn toward China to purchase spare parts, including passenger seats, for their own railway networks.

  1. This design has been around for at least 15 years. The version shown has not improved it
