IntroductionDesigning of industrial detonation (explosion) chambers with a long service time meets certain difficulties Presently there is no comprehensive engineering method for reliable calculation of dynamic stresses in different points of chamber body with arbitrary shape Different numerical methods concerning the dynamic loading of structures need to be verified experimentallyIf to analyze the published works next conclusions can be made In [1] only ideal shapes like sphere and cylinder are considered and derived formulas are suitable for the preliminary estimations only Some investigations show that stresses can differ substantially (in 2 ndash 25 times) in different points of a chamber body [2 3] The other works also have shown the existence of stress concentration in a chamber shell during the explosive loading [4-6]

With the help of the sensor 7 the greatest stress in a cylindrical shell was measured
With the help of other sensors 234568 the stresses were measured at the specific points of chamber body

In KIP-02 chamber stress concentration was decreased substantially
Determination of equivalent stresses
In compliance with measured deformations εr(t) и εf(t) with main directions r и f stress-strained state was determined by formulas σr = E(εr + μ εf)(1- μ) σf = E(εf + μ εr)(1- μ)Equivalent stress σэ=( σrsup2 + σfsup2 - σrmiddotσf)sup1primesup2 Sperical air-blast impulse J=2ρ0middotr(2Q)3Rsup2 ρ0 - charge density r - sperical charge radius m ndash charge mass Q - specific heat energyPeak stress at point 9(r) according to (Мещеряков ЮП Стояновский ОИ Расчет максимальных напряжений в металлических дисках возникающих в результате воздействия импульсных нагрузок Известия ВолгГТУ 3 (41) Волгоград 2008 144с) (σru)мах =124middotJmiddota0middotr2hsup2 r - disk radius a0 - sound speed in metal h ndash disk thickness J - specific impulse

Dependence of stress in the cover of the chamber on the mass of explosive charge
If the charge mass is m = 02 kg than calculated stress in the center of the cover is (σru)мах=115 MPa Measured value is σэ=101 MPa
The difference between the measured values was 14 that under the made assumptions and measurement errors can be considered to be satisfactory
717
Dependence of stress in the chamber bottom on the mass of explosive charge
Calculated value э in the point 1(r) obtained by finite element method exceed the measured value by 10 In spite of the fact that there was made the increasing of the bottom thickness (175 times more comparing with ellipsoid thickness) stresses are still maximum for shell
817
Dependence of stress in the chamber bottom on the mass of explosive charge(edge of the
thickness change point 2)
The purpose of measuring stress in point 2(rf) was to made sure that the thickness
decrease on the edge of the disc didnrsquot lead to stress increase above the legitimate value
Values of the hoop stresses σf are less by 10-25 MPa against to largest in this point
radial stresses σr and equivalent stresses σэ are between of them what indicates that the maximum stress values σr and σf take place when the corresponding waves of the shell
oscillation does not in antiphase

Equivalent stresses in point 7(rf)
One can see the typical oscillation of
amplitudes - the superposition of oscillations leads to a periodic increase in the amplitudes on the background of the waves attenuation Distinctly seen 5 such amplitudes with period T=1710-4 s Between them we can see about 10 oscillations with lesser amplitude and
period is about T=1710-4 s which correspond to wave-length L= T a= 085 m (here a= 5103 ms ndash sound speed) ie chamberrsquos body length in longitudinal
section between flange and disc One can suppose that there is the oscillation superposition at laquorraquo and laquofraquo dimensions with close frequencies

ConclusionAnalysis of the stress-strained state of the detonation chamber ldquoKIP-02rdquo shows
1 Maximum stresses arise on the poles of the cylindrical (short cylinder) detonation chamber and in the central section of the cylindrical shell Despite the fact that there is the thickening in the center of the elliptic bottom which thickness at 175 times more than thickness of the cylinder stress in the center reaches 150 MPa that 15 times more than stress in the lockrsquos cover and in the middle part of the cylinder
2 The results of numerical calculations of the stresses were obtained ( without product pipeline) for the points of elliptical bottom and poles of cylindrical chamber The calculated data is reasonably well approved by the results of measurements
3 Investigations of the stress condition of the shell near the orifice thickened bottom disc and in the place where the cylinder runs into the ellipsoidal head showed that these particularities led to rising of stress values not more than 25 Maximum stress near the product pipeline is in the point located more closer to chamber pole

Dependence of stress in the chamber bottom on the mass of explosive charge
Calculated value э in the point 1(r) obtained by finite element method exceed the measured value by 10 In spite of the fact that there was made the increasing of the bottom thickness (175 times more comparing with ellipsoid thickness) stresses are still maximum for shell
817
Dependence of stress in the chamber bottom on the mass of explosive charge(edge of the
thickness change point 2)
The purpose of measuring stress in point 2(rf) was to made sure that the thickness
decrease on the edge of the disc didnrsquot lead to stress increase above the legitimate value
Values of the hoop stresses σf are less by 10-25 MPa against to largest in this point
radial stresses σr and equivalent stresses σэ are between of them what indicates that the maximum stress values σr and σf take place when the corresponding waves of the shell
oscillation does not in antiphase

Superimposition of the sensors data 7(r) 7(f) Stress dependence on charge mass (point 7)

Equivalent stresses in point 7(rf)
One can see the typical oscillation of
amplitudes - the superposition of oscillations leads to a periodic increase in the amplitudes on the background of the waves attenuation Distinctly seen 5 such amplitudes with period T=1710-4 s Between them we can see about 10 oscillations with lesser amplitude and
period is about T=1710-4 s which correspond to wave-length L= T a= 085 m (here a= 5103 ms ndash sound speed) ie chamberrsquos body length in longitudinal
section between flange and disc One can suppose that there is the oscillation superposition at laquorraquo and laquofraquo dimensions with close frequencies

ConclusionAnalysis of the stress-strained state of the detonation chamber ldquoKIP-02rdquo shows
1 Maximum stresses arise on the poles of the cylindrical (short cylinder) detonation chamber and in the central section of the cylindrical shell Despite the fact that there is the thickening in the center of the elliptic bottom which thickness at 175 times more than thickness of the cylinder stress in the center reaches 150 MPa that 15 times more than stress in the lockrsquos cover and in the middle part of the cylinder
2 The results of numerical calculations of the stresses were obtained ( without product pipeline) for the points of elliptical bottom and poles of cylindrical chamber The calculated data is reasonably well approved by the results of measurements
3 Investigations of the stress condition of the shell near the orifice thickened bottom disc and in the place where the cylinder runs into the ellipsoidal head showed that these particularities led to rising of stress values not more than 25 Maximum stress near the product pipeline is in the point located more closer to chamber pole
