继续上次的课题,我们成功地找到了那辆商用车噪声的问题所在,说来真有些意外,竟然是装配问题。试验车是辆新车,行驶里程不过1 000km,我们起初怀疑过差速器齿轮配合间隙问题,但考虑到上述原因且该车是已大量投放市场的较成功车型,便把这怀疑放到了次要位置上。没想到,最后的问题真的出在这里。严谨,不忽略任何细节,不作想当然的假设,是我在这个项目中的一大心得。当我们发现问题后,我们仍从客户那里订购了一个装配正确的后 Continuing from the previous issue, we successfully found the noise problem in that commercial vehicle.
