章节摘录

　　The term ergonomics is synonymous with human factors engineering.We often see referenceto the good or bad ergonomics of an automobile interior or a household appliance.A machine de.signed with poor ergonomics will be uncomfortable and tiring to use and may even be dangerous.（Have you programmed your VCR lately，or set its clock？）　　There is a wealth of human factors data available in the literature.The type of information thatmight be needed for a machine design problem ranges from dimensions of the human body and theirdistribution among the population by age and gender，to the ability of the human body to withstandaccelerations in various directions，to typical strengths and force generating ability in various posi.tions.Obviously，if you are designing a device that will be controlled by a human（a grass shortener，perhaps），you need to know how much force the user can exert with hands held in various positions，what the user’S reach is，and how much noise the ears can stand without damage.If your device willcarry the user on it,you need data on the lildts of acceleration that the body Can tolerate.Data on allthese topics exist.Much of it was developed by the government which regularly tests the ability ofmilitary personnel to withstand extreme environmental conditions.Part of the background research ofany machine design problem should include some investigation of human factors.
