By the combination of product family data model and product family evolvement process,any evolvement process of product master structure,product group and product in product family lifecycle was available.
Mass customization has becoming the main production way of the 21th century. And the product developing is the heart of realizing MC. This paper studies the bicycle combing the technology of product developing,and the product master model,master document,master structure of the product are established on the basis of ABC analyses for parts and parameter of bicycle.
When the mass ratio of primary equipment is 30% of the mass of the floor and the period ratio is between 0.8~1.0, interaction is obviously effective to reduce seismic response for the primary structure. The reduction ratio of displacement and bottom shear force are up to 25% and 15% respectively.
Based on modes of the primary structure, the interaction between MTMD and primary structure is studied, and complex inertia mass is presented which explains clearly and briefly the action mechanism between MTMD and structure.
The analytical formulas for determining optimum parameters of passive control devices used to link two parallel structures based on the principle of minimizing the averaged vibration energy of either the primary structure or the two parallel structures under a white noise ground excitation are firstly derived, and the influence of the structural parameters (damping ratio, mass ratio and natural frequency) of the system on the passive control effectiveness through three diffent numerical examples is also investigated.
The Middle Kunlun fault (F10), which is the main structure of the Kunlun fault zone, is a high angle, super-deep fault.
Under the vitrification conditions (143-138 K) in 11.1 molal solution hydrate-separated ion pairs are the main structure units.
It is revealed that, in the absence of strong hydrogen bonding, the main structure-forming function in crystals is fulfilled by intermolecular contacts of two types, namely, staking contacts of parallel and antiparallel molecules.
The main structure of the membrane is shown to be an fcc lattice with a=14.308 ?.
At inductions up to 1.4 T, the main structure undergoes strong dynamic fragmentation.
The major structure of sensing head using in the test of cable tension is elastic annular.
Taylors Fault, a major structure that formed during D2, hosts the veins which infill dilatational jogs opened during sinistral-normal reactivation of the fault in D4.
The cerebellum is considered to be the major structure involved in classical conditioning of the eyeblink response.
Successive resection of the antero-medial (AM) and postero-lateral (PL) bundles of the ACL demonstrated the AM bundle to be the major structure involved in the limitation of tibial displacement in the anterior drawer test.
When ABO4 type compounds are plotted based on the two variables, k=rA/rB and t=(rA+rB)/2rO, where rA, rB, and rO are the ionic radii of A and B cations and divalent oxygen, they can be classified into the major structure types.
