In MacPherson strut applications for automotive suspension systems, the desired coil spring reaction force vector that minimizes damper friction and king pin moment is typically determined by Statics/Kinematics calculations. There is not a single device available on the open market today which can simulate the coil spring reaction force vector within the suspension system. Such a programmable coil spring reaction force generator was developed in 2003, and was then improved in 2013 from the standpoint of accuracy, durability and reliability. Using this modified device, the relationship between the spring reaction force vector and damper friction, as well as spring reaction force vector and king pin moment, can be experimentally studied to confirm vehicle characteristics without actually making any prototype coil springs. The validity of this device was proven by comparing to actual coil spring based testing data. Depending upon the desired characteristics of a particular vehicle, the requirement for the coil spring reaction force vector can be experimentally determined with this device. To aid in this effort the device was designed in a universal manner for any strut application by mere replacement of strut-dependent seat adapters. This paper describes how beneficial this device is to determine the ideal requirement for coil spring reaction force vector via actual measured data.

Structural analysis of some molten materials by X-ray diffraction. Part 2.—Li2SO4, Na2SO4 and the mixed system

The structures of molten Li2SO4, Na2SO4 and their mixtures have been examined by consideration of the radial distribution function and the molar volume. The existence of tetrahedral sulphate ions in these molten salts has been demonstrated. S—O and O—O distances for the sulphate ion in the molten state are 1.500 and 2.450Å, respectively. A close packed arrangement of sulphate ions appears to be the configuration realized in molten Li2SO4; the calculated correlation function based on this structural model is qualitatively in good agreement with the observed one. In molten Na2SO4, sodium ions probably occupy a position intermediate between the edge and face sites of the sulphate ion; the nearest-neighbour distances of Na—S and Na—O pairs are 2.8 and 2.33 Å, respectively.

溶融NaBeF3塩中のナトリウム,フッ索の日己拡散係数,およびその温度依存性が24Na.18Fをトレーサーとする毛細管浸濃法により,Arreheniusの式を用いつぎのように求められた。これらの結果とすでに求められた溶融Li2BeF4とLiBeF3塩中のリチウム,フッ素の自己拡散係数を比較し,また他の溶融塩および溶融ケイ酸塩中の陽イオン,陰イオンの自己拡敬係数を比較することにより,溶融フルオロベリリウム酸アルカリ中のアルカリイオンとフッ化物イオンの自己拡散の機構を検討した.その結果,アルカリイオンは典型的なイオン性液体中でのそれらとほぼ同じ拡散機構を示すが,フッ化物イオンは大きなフルオロベリリウム酸錯イオンの回転と,近接した錯イオン間のフッ化物イオンの交換をともなった拡散をするであろうと推定された。

Structural analysis of some molten materials by X-ray diffraction. Part 5.—LiCl, PbCl2 and their mixtures

Journal of the Chemical Society Faraday Transactions 1 Physical Chemistry in Condensed Phases (1978)

Hideo Ohno Mitsugu Yoroki Kazuo Furukawa Yoshiki Takagi Tetsurō Nakamura

The molten structure of PbCl2, LiCl and their mixtures were examined by X-ray diffraction analysis. In molten Pbcl2, each Pb atom is surrounded by about eight Cl atoms at a distance of 2.92 Å, which is near to the sum of the ionic radii of Pb2+ and Cl–. It is expected that only very few rigid complex anions will be present in molten PbCl2. The results of X-ray diffraction analysis in molten PbCl2 are consistent with those of Raman spectroscopy. The average Pb–Pb interaction in the molten state should be intermediate between a b.c.c. and an s.c. arrangement and the s.c. arrangement takes precedence with increasing LiCl concentration.
