Abstract : calculation of the module of a 45 pressure angle involute profile for a tapered splined shaft substituting for a delta profile is studied in this article . the formula of calculation is deduced and the influence of unsuitable module on contact zone is also analysed 文摘:讨论了锥三角齿花键轴用45压力角渐开线齿花键轴代替时，如何计算模数的问题，并推导出相应的计算公式，分析了模数选择不当对接触区的影响
This article takes the lagrange equation as the principle , establishes mathematics modeling to the inertia brake vibration when it brakes , then simulates it with matlab . this paper educed the relation equations between , which are the inertia brake ' s friction coefficient of the brake ring and the friction disk , the mean radius , the braking force , rotation inertia of the driving top and the spline shaft , spiral climbing angle of the brake ' s concave - convex helicoid , the mean effort radius of the concave - convex helicoid , elasticity coefficient of the spring , quality of the driving top and the spline shaft , rotations inertia of the brake ' s rotation part besides the driving top and the spline shaft , suppresses sleeve . provides the theory basis for the inertia brake structure optimization 本文以拉格朗日方程为理论基础,对惯性制动器在制动时的振动进行数学建模,然后用matlab对其进行仿真,得出了惯性制动器在制动时振动角频率分别与制动环和摩擦片之间的摩擦系数、制动力的平均半径、主动顶和花键轴的转动惯量、惯性制动器的凹凸螺旋面的螺旋升角、凹凸螺旋面平均作用力的半径、弹簧的弹性系数、主动顶和花键轴的质量、惯性制动器除主动顶和花键轴外其他部分的转动惯量和、顶压套的质量等惯性制动器各零部件的物理参数之间的关系,为惯性制动器的结构优化提供了理论依据。
A general analysis of mc method and technology in project management ( pm ) is proposed in chapter two . firstly , the problems are described in the practice of pm in juhua and wanxiang after the frame of pm implementation is introduced . then the problems are also described in building pm systems , based on the analysis of function and structure of pm systems at present the rationality and modularization of pm tasks are studied in chapter three 首先提出了企业项目管理的实施框架结构，并结合衢州巨化集团6万吨年离子膜技改工程等项目和杭州万向集团福特花键轴( f81w - 4780 - aa )的案例分析，指出企业项目管理方法存在的问题；然后分析了企业项目管理系统的功能结构，指出在实际企业项目管理中，企业项目管理系统遇到的困难。
Enterprises have recently encountered many problems in the project implementation process such as scheduling multi - project tasks , too much resource wasting , and the trouble that project management ( pm ) systems ca n ' t dynamically and timely agree with practical project management requirement . therefore , work breakdown , scheduling and project management building systems based on mass customization ( mc ) are analyzed and studied , combined with the case of practical difficulty encountered in the project management processes of juhua group in quzhou and wanxiang group in hangzhou . the content of the paper is as follows : in chapter one , pm history and current study status , relevant concepts , management tools and technology are introduced 本文在对目前企业多项目管理中出现的任务协调困难、资源浪费严重，企业项目管理系统不能及时、动态的满足项目管理需要等问题分析的基础上，结合衢州巨化集团6万吨年离子膜技改工程等项目和杭州万向集团福特花键轴( f81w - 4780 - aa )等项目管理实际，运用大批量定制( mc )思想对企业项目的任务分解与规划、企业项目管理系统的构建等进行了全面的分析和研究，主要内容如下：第一章绪论。
