The restaurant decorated in a modern style, a wide range of soft bag chairs have become an integral whole restaurant-style embellishment. As consumers, because of its small, comfortable, independent and much loved. For restaurant owners, free-standing and space is an important factor in their choice.

2 The inverse function calculation method sets the cam contour curve equation to h=, generation, = edge.
Among them, 7 is the period, and its inverse function is household 9 because the stepping motor is a pulse motor, and each pulse is equivalent to a pulse equivalent, so the discrete curve equation is ti=9 1.2.3, 2hm.lxVz is the stepper motor. Pulse equivalent, then take 123, can be divided, and find the stepping motor of this stepper motor every time interval can be found. This method has a large amount of computation, and it needs to be calculated in advance according to the motion law and stored in the single-chip microcomputer, if it is to be changed. Simply, the rate of singular throws, smashes, and strokes makes it easy to change the cam profile and become a programmable CNC cam to improve its adaptability.
4 The composition and application prospects of the virtual cam mechanism 4.1 The form of the stepper motor drives the precision screw. This form has a small transmission power and high precision. It is suitable for small work, 1 ferry, and also Into the motor, 1 moving rack and pinion transmission. This form can transmit a large amount of power, but the wheel is easy to wear to produce excessive flank clearance, so it is necessary to design an adjustment device to eliminate the gap, which is suitable for high power and low precision applications.
4.2 Application prospects With the continuous development and improvement of mechanical equipment and the extensive use of programmable controllers, the degree of automation of mechanical equipment is definitely higher and higher, and the movement laws and accuracy requirements of the follower will continue. It is increasingly difficult for traditional cam mechanisms to meet control requirements. Because this method is implemented by numerical control method, and can be modified at any time to adapt to different needs, it has broad application prospects. For example, the tool feeding mechanism in various cam mechanism automatic machine tools in food packaging machinery can replace the traditional degree of production efficiency and product quality.

Fan-type variable-pole asynchronous motor, the introduction of the introduction of the multi-phase asynchronous motor for the fan in Southeast University. The project is based on the provincial basic project and the torch juice project, based on the analysis of the mechanism of the fan-type variable pole motor. The digital model of the pole-changing motor was established, and the optimization design of the winding was carried out. The function, complete and data package, parts and database were compiled. It can be used for multi-speed motor flow fan and water pump load, with high technical content and low noise. Control simple operation and maintenance to save raw materials and other characteristics. Compared with the single-speed motor, the material saving 30, 0 into 0 system has reached the domestic leading level, and won the provincial science and technology achievements 3rd prize.
Soft bag chair is a sponge, cloth or soft leather bag named. There are two common all soft bag chairs and semi-soft bag chairs on the market. The so-called package is a totally flexible backrest and cushion are sponges, then Gapi material or soft bag made of cloth. The semi-soft bag chairs generally only cushion soft case. From the fabric, the leather chairs and fabric soft pack soft bag chairs face the choice of different, with skin, Busha choice is the same, in the end is good or better choose leather sofa fabric sofa, in fact, each has its own characteristics, The most important thing according to their own style of decoration and customer preferences.
Soft bag chairs are made of high quality wood frame inside the building, solid structure, angle in accordance with ergonomic design, better use of improved function and quality of the chair. Soft pack part made of high quality sponge, cotton high density multi-layer structure, ride comfort, spring rate, and durability.
