To provide an injection molding machine in which some hoisters having a small lifting load can be used. An injection molding machine includes a first attachment portion (51) to which a first adaptor (61) hoisted by a first hoisting tool (71) is attached, and a second attachment portion (52) to which a second adaptor (62) hoisted by a second hoisting tool (72) is attached. While a direction of the injection molding machine is changed by hoisting the injection molding machine using the first hoisting tool (71) and the second hoisting tool (72) and lifting and lowering the first hoisting tool and the second hoisting tool relative to each other, a horizontal distance (L1) between a connection portion (61a) of the first adaptor (61) to connect the first hoisting tool (71), and the center of gravity (C) of the injection molding machine is larger than a horizontal distance (L2) between a connection portion (62a) of the second adaptor (62) to connect the second hoisting tool (72), and the center of gravity (C) of the injection molding machine.

Disclosed is a granular material simulation method capable of reducing a calculation time of a particular dynamics simulation. A granular material S which is a simulation target, in which a force acting on each grain is expressed by a potential dependent term depending on an interaction potential between grains and a dissipation term depending on dissipation of energy, is defined. Physical quantities included in the potential dependent term of a motion equation of each grain of the granular material S are renormalization-transformed so that the form of a Hamiltonian expressed by a kinetic energy of each grain of the granular material S and a potential energy based on the interaction potential doesnotchange. Physical quantities included in the dissipation term are renormalization-transformed so that a rate of change of the potential dependent term and a rate of change of the dissipation term based on the renormalization transformation become equal to each other. Temporal development of a renormalized granular material S is calculated by performing numerical integration with respect to a motion equation of each grain of the granular material S.
