Six Airbags, Rear Suspension Assembly Work Practices And Operations Improvement

Based on the method of combination of theory and practice ,this article utilize the theories about work study in Industrial Engineering method ,such as method study ,motion study,exercise measurement and set time standards,and some other producing work system design methods.Referring to the application achievement of IE, it makes a systematic analysis on the big bus six-air-spring rear suspension assembly in Suzhou Kinglong chassis assembly line,and point out how to modify the work process problems.First ,this article introduce the work process and work flow in SZKL chassis assembly line,but the big bus six-air-spring rear suspension assembly is the key bottleneck of the whole line.To reduce the cost and improve the efficiency,shoren the produce period and eliminate the factor of causing waste,working on the big bus six-air-spring rear suspension assembly is the most important and representative task.After investigating deeply,making the record of process of it,working on process analysis and exercise analysis ,this article indicate that there are some imperfection in the work ground collocation,work sequence and process etc. and then constitute a project that include improving the facility equipment ,rearranging the collection of work ground .Through Therblig motion analysis,it optimize the work sequence and rhythm ,shorten or reduce the 2nd and 3rd motions such as searching and waiting .After modifying the work regulation ,use the stopwatch method and measure the time of the produe,set down the standard time and write into the process regulation.The time unit is reduced and capability of the sector is raised, by process elimination,combination ,rearrangement and simplification applied with rules for motion economy and efficiency.The line can produce only 2 big air suspension vehicles, but 10 now.The 6-air-spring big bus have become the normal product and this work has got a good profit and benefit for the Corp.
