Numerical Simulation and Experimental Validation of the Vibration Modes for a Processing Reciprocating Compressor

Figure 19

Different contact statuses of different distribution densities of the bolted joints. The purple key represents that the contact surfaces are overconstrained and some contact constraints need to be removed. The yellow key indicates that there is a very small gap between the contact surfaces.
