Abstract The mass participation is one of the approaches for notching analysis, in which the modal effective mass and apparent mass in conjunction with Miles’ equation are the basic elements to determine notched random acceleration input comparing reaction loads with the reaction loads caused by the quasi-static design loads (QSL). The quasi-static design limit load applied for the design of equipment and instruments is mostly based on experience from previous spacecraft projects and is defined, in general, using the mass acceleration curve (MAC). Procedures to calculate random load factors and the estimation of the depth of the notch (modification of input spectrum) using the mass participation are discussed. Examples and problems with answers are given.
