Four conditions of shock vibration during chain breaking have been discussed. 1. Breaking test on simple testing machine with main cylinder fixed on a foundation. In this case the only one vibrating mass is the piston, which rigidly connected the moving clamp of chain as a whole body with one degree of freedom. 2. Breaking test on testing machine with leaf spring isolators between machine and foundation. In this case vibrations of two vibrating masses with two degrees of freedom have been discussed. 3. Strength...

Four conditions of shock vibration during chain breaking have been discussed. 1. Breaking test on simple testing machine with main cylinder fixed on a foundation. In this case the only one vibrating mass is the piston, which rigidly connected the moving clamp of chain as a whole body with one degree of freedom. 2. Breaking test on testing machine with leaf spring isolators between machine and foundation. In this case vibrations of two vibrating masses with two degrees of freedom have been discussed. 3. Strength test on testing machine with leaf spring isolators. The effect of machine frame has been taken into consideration, and thus it forms a system of three masses with three degrees of freedom. 4. The effect of accumulator during breaking test. This is a problem of vibration with variable spring constant.In each case formulas for calculating shock pressure wave in main cylinder and displacements of vibrating masses have been derived. In order to clarify the characteristics of vibrations, numerical examples are worked out in each case. The results of these examples clearly show that installing the accumulator and leaf spring isolators are effective measures to minimize the influence of shock vibration.

This gantry type welding machine is an arc welding equipment developed for welding large box type construction of tens meters long. The maximum section of work piece to be welded can be 3m wide by 2.5m high. With a movable horizontal beam, the gantry welding machine can make splicing joint welding. The welding machine has drives on both sides. The fluctuation of travelling speed of machine frame is below 2%. The welding machine has two welding heads used for gas or electric welding and submerged arc welding respectively. For gas protected welding, mixed gas of 80O% Ar+20% CO_2 rich argonium mixture can be used. Non-spray efflux transit welding can be carried out under the presence of 30% Ar+70% CO_2. A tactile 2-D automatic tracing system is equipped at the welding head. The tracing precision is within 0.3mm.
