社会生活水平的提升,带动了人们对出行方式的需求,汽车逐渐普及到生活的方方面面,但人们对汽车车身设计的要求也得到了极大的提升。在汽车制造的过程中,汽车车身设计作为汽车生产的重要环节,必须要给予充分的重视,促使设计人员提出符合社会大众需求的汽车车身设计,对汽车车身设计质量的控制带来帮助。汽车车身设计质量控制对于汽车车身的质量控制有着重要的作用,如果汽车车身设计质量控制工作不到位的话,会导致汽车在之后的生产过程中难以有效地完成既定的目标,造成汽车在最终的使用过程中具有严重的问题,因而汽车设计人员及生产者必须要对汽车车身质量控制方法进行深入的研究,确保汽车车身质量控制工作的有效完成。文章通过对汽车车身设计的质量要求进行阐述,说明相关的汽车车身设计结构方式,提出切实的汽车车身设计质量控制方法,有效地对我国汽车质量的提升做出保障,为我国汽车更好地满足人们的生活需求带来帮助。 相似文献

鉴于新老桥梁设计汽车荷载模型的不同和对桥梁限载取值的研究,系统对比了不同时期、不同荷载等级桥梁设计汽车荷载效应的差异程度。根据不同的设计汽车荷载模型,以跨径为6~30m的简支梁桥为计算对象,分别计算汽车-10级、汽车-15级、汽车-20级、汽车-超20级以及公路-I级和公路-Ⅱ级汽车荷载作用下的跨中弯矩和支点剪力。研究结果表明:对于跨径L在6~30m内的简支梁桥,新老规范设计汽车荷载作用下的跨中弯矩随跨径的变化趋势是相同的,然而两者支点剪力的变化趋势差异很大。计算跨径越小,新老规范设计汽车荷载作用下的内力效应差值越小,利用新规范对老规范设计的桥梁进行升级加固越有利。 相似文献

1 21世纪汽车用户与需求将如何变化
从对汽车的社会需求来讲,21世纪的汽车必须兼顾人的需求和人类赖以生存的地球环境(包括安全与能源)的需求.对地球环境方面的考虑,不仅要求汽车制造商在汽车的设计阶段就要考虑到其回收利用,而且追求低能耗的技术和设计将是21世纪汽车制造的重要条件.因此为了达到轻量化,技术人员必将进行各种新材料的研究开发,混合动力汽车和燃料电池汽车的普及也将加快.这些技术和设计不能只满足少数几个不同的市场,而是要作为全球汽车市场的统一标准,将在日、美、欧三大地区占有相当重要的地位. 相似文献

This paper presents a robust optimization design method based on Six Sigma quality control criteria to improve the design
of a powertrain mounting system (PMS). The powertrain is modeled as a rigid body having six degrees of freedom (DOF) connected
to a rigid base by four rubber mounts, and each mount is simplified as a three-dimensional spring-damper element in its local
coordinate system (LCS). The calculation method based on energy decoupling is used to estimate the decoupling ratios of a
PMS. The location and static stiffness of each mount and the orientations of the two anti-torsion mounts are selected as uncertain
design variables, and the nominal values of these design variables are optimized to obtain a robust Six Sigma design for a
PMS. The uncertain design variables are characterized by a perturbation or percent variation around their nominal values.
The generalized reduced gradient (LSGRG2) optimization method is employed to solve the robust optimization problem, and a
second-order Taylor series expansion is used to estimate the statistical properties of the performance constraints and objectives.
The optimization results show that the robust design ensures good robustness or high reliability for the natural frequencies,
decoupling ratios, and frequency separation constraints of a PMS. 相似文献

In the globalization era, lean initiatives and environmental management systems are increasingly implemented in the automotive industry. The aim of this report is to investigate and perform structural analysis of Lean Six Sigma (LSS) and Organizational Performance (OP). Data were obtained from 252 top management leaders in the Malaysian automotive industry. This report presents the results of the Exploratory Factor Analyses (EFA), Confirmatory Factor Analysis (CFA), and reliability analysis, which are empirically verified and validated. A set of assessment measurements of LSS and OP is expected to be suitable for their characteristics and improve their competitiveness. Thus, the main objective of the analysis was to provide additional insight into the relationship between LSS and OP by examining the effects of ISO 14001 certification as a moderator. The results indicate that ISO 14001 certification does not significantly moderate the relationship between LSS and OP in the Malaysian automotive industry. However, the OP values for ISO 14001 certified companies are higher than those without ISO 14001 certification. 相似文献

This article deals with the optimal design of ground vehicles and their subsystems, with particular reference to 'active' safety and comfort. A review of state-of-the-art optimization methods for solving vehicle system design problems, including the integration of electronic controls, is given, thus further encouraging the use of such methods as standard tools for automotive engineers. Particular attention is devoted to the class of methods pertaining to complex system design optimization, as well as approaches for the optimal design of complex systems under uncertainty. Some examples of design optimizations are given in the fields of vehicle system dynamics, powertrain/internal combustion engine design, active safety and ride comfort, vehicle system design and lightweight structures, advanced automotive electronics, and smart vehicles. 相似文献

In this paper, a simple design method for improving the performance of an interior permanent magnet synchronous motor (IPMSM),
for driving the air-conditioning compressor used in hybrid electric vehicles, is presented. There are many design methods
that optimize the IPMSM. Each method deals with a variety of design factors, such as slot opening, pole arc, and rotor shape.
However, as the number of design variables increases, a lot of modeling and analysis time is needed in order to improve the
characteristics of an IPMSM. This paper demonstrates that the optimization of a double-layer IPMSM, satisfying the given design
conditions, is possible with only a flux barrier shape design. Then, response surface methodology is applied as the optimization
method, and the validity of the design approach is verified by comparison with test results. 相似文献
