第2题:

关于单轮式横向力系数SFC测试系统正确的说法有()。


A.测试轮的偏置角为20°
B.测试轮胎的气压与垂直荷载应符合B.ZZ-100的要求
C.未在标准测试速度范围条件下测试的SFC.值必须进行速度修正
D.SFC.值不存在温度修正问题

答案:A,C
解析:
与行车方向成20度偏角并承受一定垂直荷载的测定轮,以一定速度行驶在潮湿路面上,测试轮胎所受到的侧向摩擦阻力与垂直荷载的比值,称为横向力系数。测试轮静态垂直标准荷载:2000N土20N。测试系统的标准测试速度范围规定为50km/h土4km/h,其他速度条件下测试的SFC须转换至标准速度下的等效SFC值,标准现场测试地面温度范围为20℃土5℃,其他温度下测试的SFC值须转换至标准温度下的等效SFC值。系统测试要求地面温度控制在8-60℃范围内。

第6题:

下列有关路面横向力系数评定的说法,正确的是( )。

A.路面横向力系数按SFC的设计或验收标准值进行评定
B.SFC代表值为SFC算数平均值的上置信界限值
C.当SFC代表值不大于设计或验收标准时,以所有单个SFC值统计合格率
D.当SFC代表值小于设计或验收标准时,评定结果为不合格

答案:A,D
解析:
SFC代表值为SFC算数平均值的下置信界限值。当SFC代表值不小于设计或验收标准时,以所有单个SFC值统计合格率。当SFC代表值小于设计或验收标准时,评定结果为不合格。

解析:
横向力系数采用单个合格率和SFC算术平均值的下置信界限。

第8题:

(b) The Superior Fitness Co (SFC), which is well established in Mayland, operates nine centres. Each of SFC’s

centres is similar in size to those of HFG. SFC also provides dietary plans and fitness programmes to its clients.

The directors of HFG have decided that they wish to benchmark the performance of HFG with that of SFC.

Required:

Discuss the problems that the directors of HFG might experience in their wish to benchmark the performance

of HFG with the performance of SFC, and recommend how such problems might be successfully addressed.

(7 marks)


正确答案:
(b) There are a number of potential problems which the directors of HFG need to recognise. These are as follows:
(i) There needs to exist a sufficient incentive for SFO to share their information with HFG as the success of any
benchmarking programme is dependent upon obtaining accurate information about the comparator organisation. This is
not an easy task to accomplish, as many organisations are reluctant to reveal confidential information to competitors.
The directors of HFG must be able to convince the directors of SFO that entering into a benchmarking arrangement is a
potential ‘win-win situation’.
(ii) The value of the exercise must be sufficient to justify the cost involved. Also, it is inevitable that behavioural issues will
need to be addressed in any benchmarking programme. Management should give priority to the need to communicate
the reasons for undertaking a programme of benchmarking in order to gain the full co-operation of its personnel whilst
reducing the potential level of resistance to change.
(iii) Management need to handle the ethical implications relating to the introduction of benchmarking in a sensitive manner
and should endeavour, insofar as possible, to provide reassurance to employees that their status, remuneration and
working conditions will not suffer as a consequence of the introduction of any benchmarking initiatives.

第9题:

路面横向力系数SFC代表值为SFC算术平均值的上置信界限值。()


答案:错
解析:
路面横向力系数SFC代表值为SFC算术平均值的下置信界限值。SFC代表值=SFC平均值-ta/√n×S(标准差)。
