| Abstract: | The earth pressure application mechanism,the calculation formulae diagrams of the lateral pressure of bulk goods in various countries are described.With the earth pressure theory,the application mechanism of bulk goods upon the end walls and side walls of gondola cars is analyzed comprehensively under the working conditions of operation and shunting.The liquid-like mechanism and solid-like mechanism in the jolt stage of operation are mainly analyzed.It is suggested to use the relevant calculation formulae o... |
