selection considerations of DAMPTAC Shock Absorbers

BACK

Jun 30, 2018

DAMPTAC can provide customers with professional solutions for energy absorption and damping control.
Selecting the most suitable buffer model requires five basic parameters:
1. Weight of moving load: m (kg)
2. Impact speed: v (m/s)
3. Impetus: F (N)
4. Number of buffers installed in parallel: n (pcs)
5. Impact frequency: c (1/h)
 
Here are some practical examples:
1. Horizontally moving objects with no additional thrust
m= 100 kg
v =1.5 m/s
c = 500 /h
n =1
 
Impact kinetic energy: w1 = 0.5*m*v*v = 112.5 Nm
Thrust work: w2 = 0
Total impact energy : w3 = w1 + w2 = 112.5 Nm
Effective weight : we = 2 * w3 / (v * v) = 100 kg
 
After the calculation, the comparison in the product specification table, DTK2525-B is most suitable for this application.
 
2. Horizontally moving objects with cylinder thrust
m= 100 kg
F = 2000 N
v = 1.5 m/s
c = 500 /h
n =1
 
Impact kinetic energy: w1 = 0.5*m*v*v = 112.5 Nm
Thrust work: w2 = F*s = 70 Nm
Total impact energy : w3 = w1 + w2 = 182.5 Nm
Effective weight : we = 2 * w3 / (v * v) = 171 kg
 
After the calculation, the comparison in the product specification table, DTK3035-B is most suitable for this application.
 
3. Free fall movement
m= 60 kg
h = 1 m
c = 500 /h
n =1
 
Impact speed: v = sqrt(2*g*h)= 4.4 m/s
Impact kinetic energy: w1 = 0.5*m*v*v = 588 Nm
Thrust work: w2 = F*s = 44 Nm
Total impact energy: w3 = w1 + w2 = 632 Nm
Effective weight: we = 2 * w3 / (v * v) = 65.3 kg
 
After the calculation, the comparison in the product specification table, DTK3035-B is most suitable for this application.
